 Hi, I'm Claire, a self-confessed bird stalker. I spend a lot of time out in the bush watching and talking to birds. This is what a behavioral oncologist does. I investigate the lives of superb variants to understand how their resources affect how they can invest in the next generation. As birds don't have money, the most they can invest is their resources. But many species have gone extinct when the resources they rely upon disappear. This was the first seven-day-old baby faireran that I color-banded so she had a name. I have studied these birds for five years and don't want to see them also face extinction. The question I often ask my birds is how can I help? The only problem is I don't speak bird. Luckily for me, birds show us how much their resources matter with the size and weight of their eggs. But like many mothers in our society, mother birds can't always provide the best for their babies. Although a two-gram egg may seem tiny to us, a clutch of superb faireran eggs can weigh up to half the body size of the mother, requiring her to have resources to invest. The big problem is that the mothers rely on their environment for these resources. But climate change is making the environment more extreme, meaning years are either life or death. Years that have plenty of rainfall and food available are like birds have been born with a silver spoon, whereas drought years, food is scarce and conditions are tough, but birds can't get a second job to help provide for their babies. Rather than writing a bird barefoot investor book, we need to understand what it is they can't live without. The population I study is a wild one and is at the mercy of the camera climate, which we know can be volatile. During my fieldwork, I spent months lugging water, eggs, mealworms and a special supplement through Campbell Park to nourish some of my birds and to assess if resources are the limiting factor for egg investment. I then patiently watched to find where the Wrens built their nest and measured the eggs produced both with and without extra resources. I found that the resources mothers have are really important in determining how much they can invest, as those with more resources produced heavier eggs. And we know this affects their babies' growth and survival. All animals, including ourselves, do what they can with what they have to give their children the best life possible. But with our world having lost so many wonders already, I want to ensure these little blue Wrens are around for my children and my children's children to enjoy stalking as well.
