 Welcome back. I would have thought that we are facing some technical problems. Hopefully the audio will remain stable. And at this point I'd like to welcome Coco, who supports chaos at school in parts and who clearly is interested in singing birds. As you will be able to find out how these birds can be seen and watched and mapped live. And she will explain to us how that works. And there will be some interactivity, which means that I will use the chaos pad that we have in the wiki and the pre-talks wiki that we've linked to. I will be watching that wiki. And if you have any questions, you can put them in there and I will pass them on. And then we will try to work on these questions immediately and turn it into a real interactive experience and a spontaneous workshop. I'm looking forward to that. So Coco, you go ahead. Yes, thank you for the intro. Thanks for being here. I would like to tell you why you map singing birds. That's all why that is important and how that is organized. And with you, I will then use the QGIS software to look at data sets, current data set to see what the population is and where they are. And if you want to join in, it would be good if you could install the QGIS desktop now. That is a tool to create maps. And if you get lost, if you want to ask questions, try something else, then use the usual channels as has been explained just now. Right. I have four or six slides here. I hope you can see them. And the first one asks, why do you actually record birds? You know they are tweeting about and your balcony, but why is that interesting? Who is interested in that? But in environmental politics and decision making, to have a good foundation for these decisions or to make the right demands from politics, you have to have reliable data. You cannot just say protect the birds. You have to be able to say, well, look, the population of this or that species has been declining by 80% in the last few years. We have to save them. That's why the Federal Republic of Germany, but the EU also is recording some indicators. And these indicators are supposed to reflect how habitats, agrarian areas and others are changing. And these indicators are then used when you have to argue for certain legal changes or whatever. Germany actually has an indicator called biodiversity and landscape quality, which sounds very comprehensive. But in practice, the whole of this indicator is only related to birch species. The whole landscape type is connected to the species that you would expect there and then it's checked whether they are still there. And that then gives you a percentage saying what the quality is like. And the EU has a number of other indicators, again, related to landscape types and species that are supposed to reflect how intact the nature is. And our German index on biodiversity and landscape quality is divided into landscape type, which is agrarian areas, which is normally where the issues are worst. Forests which are supposed not to have changed and populations are supposed not to have changed. We have separate areas, inland waters and seas. Of course, you have very different birds in each of these. And each landscape type has been assigned a number of species and the map has then go out every year and see how many of the birds are still there in certain designated areas. And on that basis, there is an evaluation how intact that landscape is. And in a way you can say that Germany makes political decisions depending on birds, certain species and depending on how many of these are flying about. But these data have to come from somewhere. And Germany does not employ tens of thousands of mappers, but these in fact are volunteers. And the German Office for Environmental Protection I think is the name, has outsourced the whole thing to an association of volunteers that has 1,650 volunteers in place and these are onisologists. They have been roped in. Each of them has a certain area that they let go and map what kinds of birds they saw where and we will now deal with this small spot near Hanover which I have been mapping for the last two years. So I have been out there for eight times altogether starting in March and ending in June every year and there are four times preset where you are supposed to be there from sunrise for about two hours. You walk along a certain line and count and you can see those red spots. These are the actually assigned areas which are actually getting mapped and the green spots almost the same number. These are the areas that should be mapped for a representative sample but for which no volunteer bird has been found yet which tells you that our German indicator has huge gaps for certain landscape types because it doesn't register the areas that it's supposed to register. So if you know about birds, you are very welcome to show up. This really is fun. Right. And then you get to what actually caused me to hold this workshop and this is a systematic approach. There has been one since 1989 and until the last year, this was very traditional on pen and paper. So we have, we were given some printouts of our maps. We went out with those into the landscape or into the settled area in my case and whenever you heard a bird, you wrote, you've made a note in the map what species that was and maybe what the bird did at the time. So this bird was singing. This bird was feeding and so on. And after the third time around, you sat down on the computer at home and you then take a blank map for each species and all the birds that you've registered, you copy into that map and you then take another map and you take the next species and take that from the old fold of the field maps that you had and put them in there. So you had four field maps that created one species map with different colors for each watching period and you could then circle in. If in a certain period of time you'd seen the species, then that was regarded as a relatively safe breeding area. Some species of course migrate. Some do that early, some later in the year and depending on when they migrate, that changes where they settle and if I find a certain bird in April, a tit perhaps, I will then assume that it will be breeding there. And for swifts in April, you can be quite certain that they'll be still migrating. Only when you see them, if you see them around June, can you assume that this is where the bird is actually breeding. So you can then find out the dots you have in what colors and you can then circle in certain spots. Now since this year, this has been digitized. Digitalized. There is the naturalist. Yeah, that is a pun. And that has existed for a few years and everyone that counts birds as a hobby uses this and that is where you enter your random observations. There is a portal there that I think is only there to collect bird observations and then there are more or less scientific evaluations to run on that basis and that includes the indicators that the state has set up and the EU and the way they relate to the markings in your area and you then refer to this platform called Ornito. So anyone that is very serious in bird watching will enter their data there and the line you have to walk along as a systematic mapper can be included on the map, can be faded in and you actually store the exact coordinates. As you can see in this example you can choose species, you've seen how many of these birds I've seen and what they do. Is it tweeting? Is it just there? There are birds where you can actually determine the sex. So if you have a black bird that is quite important and you can distinguish them by color and if you see that you find two males you can assume two different territories. If you see a couple then it's more likely that they belong into one of the same territory and that is what you've seen. So you can see if you've seen a bird that is carrying nesting material then you can assume that this bird is not migrating through but it's actually building a nest in this area although it can actually find that nests are given up and the birds move on. If you see a bird carrying food then you can be quite certain that the bird is actually breeding and has offspring that the bird is feeding or maybe you've found a nest then you can also be quite certain that you are in a breeding area and that all you can register. I can't of course take you out into the field right now sadly and that's why I will now see what happens after the field work at home. If you want to join me in clicking you can now take this address use this address and import the point cloud from there import it into QGIS if you've started QGIS to desktop. Now these are data from people that have actually walked outside and entered the data and after the fourth walk after a few days of processing you are then sent this export and then it's up to you what you do with the data ultimately the territories that you've deduced from that you're supposed to enter into an excel sheet and send over and okay you've seen the link for a while and I'll share my screen and we will now look at and process this geotation together. Alright I hope you have installed QGIS and now we're going to open up a new project so now we're going to look at the point cloud and to do so we're going to pull it into the layer window so now we have to choose the layer we want to view. This is a polygon which is actually irrelevant because it's just the outer border of my data and now you have a white line which is a line that I walked and then you have points and each points represents one bird I registered so what we see are many points that look the same so the first question is where are we and in order to see where we are we have a very useful extension which is called quick maps services you should all install this because it's very handy I'll just leave it here for everyone to see and to remember the name and you see the quick map services up here in the tool button and we also we can blend in an OSM and map so it's an open street map map which we can see so now we see where we are and unfortunately the contrast is very strong so it's difficult to see to spot the points and we can change that in the settings if we adjust the brightness set it up a little bit and if you click apply you see what it looks like so now the background map is a little bit paler so we can see the points very well our goal is still to make maps so let's see what kind of data we have now we're going to select the layer and look at the attributes so I've named the points after the bird so let's start with the blackbirds we have points which have characteristics all of those are observation types and then we have a date which is important because we can see the month I saw the bird in while the species ID isn't so interesting atlas code that is the code for the European breeding bird atlas which is also collected from these data and this is what I entered on what the bird is doing at the moment and we have a reference list here with the codes A1 that means that I've seen the bird A2 means that the bird was singing when birds are singing loudly you assume that it's female worldwide 70% of all bird species is where the females sing more often here in northern Europe we also have a phenomenon which is that males are mostly singing especially when breeding so they're singing to their eggs in order to make their hatchlings known with their voice so here in northern European bird singing you can assume that it's male and once other male birds to go away and leave its territory and then you have the B codes which are about breeding you have different types of behavior that indicate breeding for example building a nest and then you have the C types which is about secure breeding so when a bird is actually sitting in the nest and breeding or if you see hatchlings those are behaviors which we have as atlas codes ID form I actually have no idea what this is but species name is their species of course and direction is relevant if you're in an open field and you see a bird disappear or appear you can track the direction it's moving in but because we're in a populated area and you can't look far into the field only registered sitting birds so it makes sense to filter by species so now we just have one species in the map are there any questions is everyone getting along well ok so I'll just continue in order to split the map we're going to go to the editing tool we want to split the map so we're looking for the splitter function let's see split vector layer that looks good so let's do that now we can select the field we want to split by so we say species name and now we're creating a shape layer for each kind of bird and we have to tell the computer where it's supposed to go so I'm opening a repository so we're going to make a separate folder because we're going to have many folders in the end so now we can see changes and we don't want all the species at once so I've got auxiliary files and the shape file is very important let's see what's in it so let's just drag a file into the viewing window let's just hide the other layers so these are just the blackbirds so we still don't see in the map what kind of activity we saw so let's continue with the settings and the characteristics so we have markers here colored markers and we're going to opt for rule based now you can refine the rule so you can give it a sense we want to categorize so actually we would need to sort by date but unfortunately the dates are in text as we just saw the month is written in text but you can split the text so let's go into an editor and let's make numbers from the words so the first text after a space is our month because in May 2020 for example May would be the first word after a space and now we found those classes I don't know what the one without the date means but now we split it the names of the months and now we sorted them with this now let's apply that now we have colored points color is one walk sometimes I did walks but I didn't find securely breeding birds so sometimes events are atypical so we need to label them in a way that makes sense later so let's go to label and we also want to establish a rule here a rule based labeling so now we're adding a rule we're going to walk and now we want to paste the date and we also want to know what did the bird do so we also need the atlas code so it's very handy that we have a contact function here so we have a raggitz and that strips the month from the date string and we're going to concat it with the atlas code so this should be it let's see if it works yeah now we have the name of the month and the atlas code so let's close that and now we can add the open street map layer again we've got a problem here because it's very difficult to distinguish between the labels and the street names so we have to try and find a better way of making it visible so let's go back into the characteristics so we have still the labeling selected and we're going to open it again so we want a text buffer which is the small space between the letters that we see on the map so let's see now we see that it looks better we have a little white space behind the letters so nice you can actually read the labelings we could also add some shadows if we want that's a matter of taste personally I don't like the shadows so I'm going to remove it so buffer yes shadow no apply so that's enough for styling now let's look at the reading territories so we're going to zoom using our mouse wheel and now we would have to look into the table which tells us what kind of event we're dealing with and we have a list of species and we have walk numbers so the number of walks you've seen the birds you can consider the bird to be for example definitely breeding so in March, no March, April and June so we are going to look for black birds during these walks let's go back to QDIS where is it I'm sorry so June black birds are already irrelevant because they're back to migrating so in order to map the birds we need a vector layer of the directory type no not this button was it this one layer of the poly type so now we have the borders of the territories they're called paper territories because they're not real territories because you can't exactly define the territory of a bird because you would have to watch them all day and you would have to watch the birds behavior and for example how they behave with neighboring birds so now we're going to find rough territories so called paper territories so we have to save the polygon layer somewhere I'm going to put it into the species folder and select the species black bird and it's going to the editing mode and start adding objects to the layer in QGIS you have three types of layers you have interface only contains points line layers which only contain lines and polygon layers which only contain polygons so you can't really make a next layer but you do three separate layers which you put on top of each other so now we're going to add a polygon layer to the point layer which we already have so we saw a black bird at the church in May and April so we saw two separate birds well there was one in June that may have been the same than in May so what I am going to do now is that I'm going to assume that those birds are the same so I'm assigning them one ID and maybe those two could also be the same so I've got two territories here and then we've got this March and April sighting in A1 we only saw it and in A2 it was actually singing so when the boat was singing I'm assuming that it's male maybe I even saw that it's black and directly we had a black bird that was singing in June and in March and in May it's interesting that we have different black birds in March so those two black birds are definitely not the same bird so we can mark two territories let's continue up here we have three black bird sightings in March there are three different birds because we saw them on one walk normally birds choose landmarks as territory marks so for example they might choose a path or a garden or a tree as their territory markers and roads are sometimes dividers between territories actually two birds one in the front garden and one in the back garden so we've got one bird in May here but only in May but birds can fly so maybe it was just looking for something to eat here so this is one territory because we saw the same bird in March and April May and June because this bird has been here in May and here in April this one in April must be a different bird continue up here at the cemetery we have the most birds at the cemetery actually we've seen one in May here and now it's getting tricky we have our first buck the gender of the bird was saved but it wasn't recognised by cuges I would say two birds in May but my memory says otherwise because I remember that this one was a female and that this one up here was male so probably we have a couple here the same up here I saw two birds in May closely together and I had to look back into my records to see one of them was brown in many species of birds the females are green or brown because they sit in the nest most of the time so it's advantages if they're not recognised so easily by cats or other predators so the nice and beautiful colourful females just died out or were eaten and males however actually distract from the female so they often have one spot that is very colourful and if they show and flash their colours you can assume that they are trying to distract from a nest so I remember that these were two black birds so two males this one is lonely but so we have one territory here at the mayor's office so it might be one of those who just switched for looking for something to eat so in order to not disturb the statistics I'm getting to just mark it as an uncertain territory and confirm it later so now I would just enter it into my excel sheet like that so we've got 15 15 black bird territories in total so let's go on with the next bird we're going to hide the black birds for now let's see who will choose let's use the black red starts I'm sure you've seen them this is a bird that likes to sit on rooftops and I haven't seen that one as much as the black birds it would be nice if we could all use the settings we made on the black bird layer and use that for this one as well that is possible because you can copy the style so copy style is a command in QS I'm going to go to the black red start layer I chose the wrong one there and copy and then say paste style and immediately we have these labels separated which include the month and the id and you can save doing this click 100,000 times you can see taking all the maps that you have we've had the one with black birds already so drag them all into the window which takes a while here they are and you can then select all of them and paste style again all the species maps that we had split earlier are there and have the same kinds of labels of course this is now a huge mess of dots so we will now hide them away with all these layers finally some quiet let's get OpenStreetMap back in and where are the black starts and you can do the same with all the other layers you can do the same thing we did earlier now create those polygons now set the layer to edit and happily start marking territories for the black red start I don't think I have to run through the whole process again it works just as it did earlier with the black birds and once we've finished mapping now take use the spreadsheet that is the document will send to the German association of ornithologists it looks a bit chaotic but it isn't because it has all the bird species that are in the catalogue of species to be monitored and of these 99 species only 20 or so will occur in settled areas and at the top I'll enter what kind of landscape we were doing our mapping in and this was village, garden city small holdings part of the sample area was industry that was the railway tracks now we'll enter the species and how many territories in which kind of landscape and we don't have so many species here for the ones we want we would then enter our black bird territories and the habitats the habitat of village or garden city and you guess where are you here you are and then see whether in the industrial areas we found any black birds no we didn't if we did we would enter these birds under industry and this would occur in forests we didn't have any agrarian areas you could debate with a cemetery as a landscape type occurred we had a cemetery but to not make things too chaotic sometimes you only really process a landscape type if they are as large as 300 meters and because this cemetery was so small we included it in the garden city landscape type because it doesn't really differ that much from the other landscape and in the excel sheet we have 23 different species and that's what you send in together with the shapefiles which are the polygons and you then leave it to the central office to calculate those indicators and that is your job and that's what you get done for the year right now that was the very first year in which we worked this way using naturalist and QGIS and I think it was a real success because you still finished earlier you don't need as much paper and you can hand your data in via email and not send in a huge envelope and therefore I hope that you will have a few questions now because I am now basically done with the demonstration so let's I have a few more links for you if you've only seen QGIS now this is where you can find the software if you want to learn more about bird monitoring use the German link for the German office for nature protection they have a fairly good German info page and if you want to join in either monitoring common breeding birds or if you haven't got that much experience then monitoring of rare birds might be more interesting because there's only one species for you to recognise there and that is the one you have to search for and for that you go to the DDA the umbrella organisation of German AV fornists and join the forum and say that you're new and would like to monitor and I and if you are more into it you can say I would like to map common birds and you have to be able to recognise these birds reliably either by shape by appearance or voice but you have to be reliable in recognising them and if you want to join in at the lower level if you sit outside often and would like to count birds then have a look at only though the German portal to report earth sightings and if you only can think of questions tomorrow you can reach me via twitter or mastodon or you can write to me via my NABU, my ornithologist association's address now I'm through and I'm interested in your questions thank you Coco that was very interesting and particularly because in these corona times there is a certain side effect nature of course is more active but at least I felt that I've actually seen a couple of birds on my shelf, robins they use the shelf for breeding if food is so close I'll have a look at the questions one has been there for a long time did you consider creating a bird did you consider a plug-in for the lookup tables that you've used in your talk a bird plug-in for these tables well, since I've only started with QQIS now I've only really saw what you can do and writing a plug-in would have been a task for the winter for it to be used next year and I would of course then offer that to all mappers it would have to look good that way all that perfectionism but on the other hand of course one or other will now have caught on and maybe someone is interested to join in that kind of work I would be happy if someone wanted to do that because chaos of course depends on people coming together and doing interesting things together so let's have a look at the next question if the QQIS setup will be kept if the setup will be kept for the coming years are there plans to extend QQIS for your work count the areas put them directly into Excel that would be a task for the plug-in again that would do the counting in the polygon layer and transfer the data and in the next few years that will gradually perhaps come about I'm very happy that I was able to use GeoJSON for the time being so even if things are not quite complete yet but surely by next year it will be more complete and everyone is just a volunteer so let's just program that on the fly and most mappers tend to be somewhat older people, retired people and all this digitalization is kind of putting them into a very new situation and they are now busy creating PowerPoint exports which is an alternative to GeoJSON and put images into a PowerPoint presentation and all that now for people that aren't really familiar with digital things these are not nerds these are hobby birders or maybe professional biologists who do this in their spare time or people that do something completely different and have an interest in birds I cannot expect them to be familiar with coordinates OSM and all that and it has to be easily usable right and you don't want to have to learn kinds of weird things all the time it has to be simple and you shouldn't have to be an IT expert and if I write a plug-in which is a very nice idea by the way then it really should simplify working with cure guests for complete novices to use that that's the task and it should correctly export the characteristics of any observed bird yes I cannot say what would have come out of that because I didn't do the registering this is kind of experimental now your move direction of movement or the birds you can actually record bird movement directions in naturalist so you can say this bird isn't stationary on the street and can then the direction of gaze can be read from the phone of course and entered and bird's direction of course will be more difficult another question which seems quite naive but actually is probably quite relevant at which kind of weather it should be sunny, dry weather and it should be at sunrise because birds there's a real bird clock where you can find which birds to expect at which time of day and they start before sunrise and exactly at sunrise you have the most activity and we think that this is because there are few insects about in the morning because it's moist and cold so that is the time when they are awake but the food is not and all other activities that have to be made are then carried out at that time that's why when birds wake up you have this amazing concert where all of them are singing everyone basically screaming this is my territory I claim this territory for myself and my partner so you try to go out in sunny weather because in dry weather this is when most birds are active if it's raining they tend to hide and tend to not want to sing so you can expect to not see many of them you should therefore check the weather forecast so if you have a one hour trip to your area and start in dry weather you should check whether it will stay dry is it dry or dry and cloudy and if there are no clouds then it's worth making the trip and you can expect then for the weather to stay dry and not to actually drive into a rain and that of course is an issue most of these areas are quite far outside I was lucky but the other areas I'm assigned require one hour trip and others have even further to travel so these people might be starting out in the night and arrive in dry weather so you are actually assigned a place where to watch boats, no you choose it you have the wet side I'll just share my screen you have a list of maps and you can choose an area which is convenient to you from the areas that are still free we also have a water bird counting event now here you can filter by state and then you can choose a district and you have red territories which are already given to someone and you can't switch because data only become illegal when a person has watched for two years because the statistics purpose is to monitor trends so it's important that you have a consistent way of monitoring because the same purpose is to have the same error rate and having someone else watch would lead to inconsistencies so you're trying to exclude systematic errors so yeah no data isn't good enough yet so we're working with you so here the green areas are still free so if you want to participate just choose a green area look at the details so for example if we want this area here we would write an email to the coordinator and say state our experience in bird watching to make yourself credible and this area is assigned to you and you're going to dedicate several years to watching the birds and normally people do that as long as they live so you're like the male black bird claiming the territory and saying that's my territory now one question on how to spot birds websites whereologists share their sightings could you use those we do that for example we have ornito.de which is an ornithologist's platform where ornithologists upload photos of their sightings and we can actually use the location data from the photos and incorporate them in our research so those are chance sightings that help us get a picture of how many species we have we have other platforms an international platform for example from an English university that collect sightings with photos and those are available worldwide we also have data from Germany but all Germans ornithologists I know use ornito but it's a matter of taste because websites have a lexicon where beginners can look up bird species and ornito is a little bit old-fashioned maybe and there's another platform which I haven't mentioned here where you can upload photos of breeding birds and you can actually record your observations like for example what the bird would do and they also help scientists identify birds and what they're doing and if you don't know the species you can upload it as a mystery and then ornithologists from all over the world try to assign the bird to a species and also well if it's not too exotic someone will actually tell you what kind of bird it is so it's a crossover between geocaching and ornithology yeah exactly geocaching is like bird watching for people who don't know about birds bird watching really you have to learn it from another person by walking along but spotting birds the next years you really need experience and you really need a teacher for that and you really have to listen very closely it take me 10 years walking along with other bird watches in order to get a certain kind of certainty which kind of bird I'm watching when I was a beginner it was more difficult for me and now I'm more experienced I'm part of a nature protection group and I was part of a walk where we told people what kind of bird we're seeing right now and then unexpectedly both of the tour leaders died and we needed someone to replace them and we didn't because we didn't want to cancel the event so I just tried to do that and so I inherited the task basically of leading the tour and I became very good at it and I actually noticed that I had become very good at this and I could actually do it so I'm now doing bird watching tours regularly it's something you just acquire over the years it's not something you can do as a pandemic project for example it takes years of dedication but it's worth it or you could start during the pandemic because we've learned that it's very good to be outside in small groups and with a lot of distance to other people so it's actually a very good thing to do right now yeah and that was the best time to begin so another question I have a question the app screenshots in the presentation they looked different than the ones linked below well they were screenshots from bird watching notifications which used different maps so this is where the differences might come from maybe they also changed nah they're from last week but it seems I was on another sub page you get the same information at BFN DDR but they always look kind of different I'm very happy that the pad is very active and that many people are listening and posting questions of course many listeners noticed that your check has a nice shape but that was that was by chance I did a hard formed walk by chance yeah it's cute so let's see if there's anything obvious or so there's one question that has been there from the beginning what kind of hardware do you use I'll explain it in German so in tracking projects you attached a GPS sender to birds in smaller birds you used to use different trackers but now you have trackers that are very lightweight and small and then you release the bird and then you have the geolocation data to track the migrating routes because birds when they migrate they make pauses and sometimes it is used to spot abnormal behavior that could indicate an earthquake for example and also you try to find the winter territories of the birds which is obviously trying to protect them so you only attach those very expensive trackers to collect birds and provide the best data and then you have lines that go all over the map if you want to participate in that as a layman and you have an app which you can use to see the geolocation data and then you can from home with your spectacles you can see if you see the bird with binoculars you can double check the data and you can also spot behaviors like for example if the birds are feeding or if they are gathering you can feed the data with your additional observations so this is a nice thing to do if you are outside if you find a tracked bird you can monitor its behavior and track its behavior also sounds like geocaching and outdoor activities with technical equipment so if it is sunny outside in the morning and you are bird watching the stereotypical node just went to bed right? or do you just stay awake all night to go bird watching in the parking lot? yeah two things you also have night active birds night birds so for night nerds I would recommend birds that are active between 10 in the evening and 1 o'clock in the morning because normal on the solid just want to be awake so they are sleeping at that time obviously or you can bat watch because for bats you can just set out an antenna and then you can track the bats and they are actually looking for people that like to do radio stuff as a hobby and then you can have a certain type of antenna which is used to track birds and to see the migrating from its behavior you can determine the species using ultrasound so bats are also night compatible species so that sounds like we need another talk for that because there is so much material to talk about like ultrasound detectors building them that sounds like so much fun and actually we have bats and I can hear them at night with my bare ears so technical equipment could make it so much more fascinating any healthy adult should still be able to hear bats because you have about 20 kilohertz for the lower tones which bats make when they are hunting but when they are not hunting they make louder sounds between 100 and 150 kilohertz and you can hear them quite well when they are hunting actually because then they are at 70-80 kilohertz and that is you can hear that with your bare ear but we are getting distracted because we were talking about birds I am having a lot of fun right now with our bat discussion at the end of our time slot so let's have one last look into the pad and it looks like all questions have been answered maybe one observation from the feedback on media.ccc.de you have talks on QGIS and there is also some type of event so if you are into that kind of thing you can look at media.ccc.de so now I would like to conclude the talk and I will also have a look at the pad and see if I can answer more questions now let's free up the slot and I can see the contact details here on the slide and I am excited to see if there is more but enthusiasts incoming at the German Nature Protection Association and I am also willing to take people along with me and show them what I am doing and I would be happy to have participants and you can also have a look at my Twitter account where I post photos of birds and tell you about my daily walks and I can also take people along for my photo walks but it might be less interesting because you are often disturbing the birds and then they go away so thank you for listening thank you for being here
