 Hello everyone, my name is Dr. Natalie Sanchez. I'm here in Santa Rosa National Park in Costa Rica. And my project is about recording nocturnal flight calls of migratory birds. We are combining cutting-edge technology using bio acoustics and using modus wildlife tracking systems to record and to detect all these birds migrating from north to south and south back to north during the migration season for conservation purposes. So one of the challenges we have overcome are the insects during the night making sounds that are masking the nocturnal flight calls. So we decided to come up with this bucket mic to be able to, because it's in a very high position, to reflect or to make sure that the only sounds that are recording are the ones passing over the microphone. And we don't want the sounds coming from these sites. And also the parabola is helping to direct the sounds to the microphone. That is why we came up with this. Device and it is working. We are actually now filtering out the insect noise and recording only the sounds that we are interested. There are the nocturnal flight calls. We usually look for a structure, a pre-existing structure, like an electricity tower or the roof of a house. And we are attaching now our bucket mic to one of the parts of the tower. And we are hoping to get birds flying high up. And we are able to record nocturnal flight calls of migratory birds.
