When I was kid, I thought I didn’t like cats. It didn’t help that every time I got near one, my eyes got itchy and my nose ran. My cat allergy disappeared around the time I went to college, where I volunteered at the local animal shelter and got a new perspective on felines. In the second year of my PhD program, I went to the East Bay SPCA and adopted a 3-year-old former stray.
I love my cat. She is 40% sweetheart, 40% terror, and 20% judgmental staring statue.
It looks like I’m sleeping, but I am watching your every move.
I am an ecologist, an ornithologist, and a bird-lover, so I know some things about cats that a lot of cat lovers may not. It all adds up to this: humans have put cats into an ecological trap, and we continue to do so, often with the best of intentions. It is not the cats’ fault. It is our human duty to get them out of this trap, for the cats’ sakes and for wildlife.
The birds are having babies, those babies are learning to fly, and they are flying into our nets at the banding station. They’re not really babies by this point: most of them are independent of their parents. They may have been out of the nest for a month or more, and are technically “juveniles” or “immatures.”
At the banding station we collect data on each bird we catch, including that bird’s age. It’s important to record the age if we can, because the more accurate we are with the age the first time we catch a bird, the more accurate we can be later. If we caught a bird in 2014 and recorded that it was a juvenile, then when we catch it in 2016, we’ll know it’s exactly 2 years old. If we didn’t bother to age it back in 2014, then in 2016 we would only know that it was at least 2. That maybe seems like a small distinction, but the lifespans of wild birds are still an area in which we lack a lot of information, so knowing exact ages is valuable.
How do you tell if a bird is a juvenile or an adult? In some species, the juveniles are dramatically different colors than the adults. Juvenile juncos, brown and streaky, look distinct from adults even from a distance—until they molt, at least. But the differences can be a lot more subtle.
Here is a Common Yellowthroat from the banding station:
How old is it?
While my previous post, grumpy as it was, is true, I left out some important things. If you find yourself in the possession of a baby bird, the best thing you can do is to get it to a licensed wildlife rehabilitator. There are a few cases, however, where this may not be possible. Some rehabbers don’t accept invasive species (pigeons, Common Starlings, House Sparrows) or domestic species (e.g. domestic ducks). Some places don’t have a wildlife rehabber anywhere nearby (although do check—you might be surprised!).
If you’re in this situation, the internet is your friend. You can find recipes for nestling bird diets and instructions on care posted by people who care for those invasive species. Don’t just try to go with your gut: your intuition is mammal-based, and will mislead you. Search for reputable-seeming internet sources, and ideally find ones where you can contact the people to get detailed advice. There is a community of starling-keepers out there who may be able to help (especially if you’ve found a starling; unfortunately, bird species do differ in the care of their babies).
The most important thing is do not try to force-feed your bird water. Birds have an opening in their throat that leads to their lungs, and it is incredibly easy to drown them. Put the bird somewhere dark and warm and do your internet research before trying to do anything else with the bird.
Also, if you do an internet search on my name, you will find my email address. I am not a licensed rehabber and am definitely not the best person you could contact, but I’d certainly prefer to be asked how to keep the bird alive, rather than asked why it died.
Please, please, please do not “rescue” baby birds if they are covered in feathers. They are fine: they are hiding, and being fed by their parents, and growing, and soon they will be able to fly even if they can’t yet. If you find a naked pink baby bird, and can’t see the nest it fell out of and put it back, then please use the internet to find a local wildlife rehabilitator and bring the animal to them. They know how to keep baby birds alive. It is difficult. If you try to raise a baby bird yourself, without specialized knowledge, it will probably die. I volunteer at a wildlife rehabilitation hospital, and our care of baby birds is complicated, from determining the diet to the amount to the best way to house and eventually release them. We are constantly advised by trained veterinarians. This is not something you should be trying to do at home unless, for some reason, there is absolutely no way to get the animal to a rehabilitator (maybe you live on a tiny island in the middle of the ocean?), and even then, you should contact a rehabilitator and ask for advice. Don’t just try to guess. You will guess wrong.
I know you want to help. I know you mean well. But good intentions will not prevent you from killing a baby bird. And then you comment on this blog to ask me why it died, and I get so many of these comments, so many stories of people accidentally-but-avoidably killing birds, and it makes me dread checking the comments on this blog in case there is another one of these stories. The baby bird died because you are not a bird and not a trained wildlife rehabilitator. Let the birds raise their babies.
I covered this is in this older post, including ways that you can help birds.
This wildlife rehabilitator has a good article on how to tell if an animal needs your help.
