A friend of mine shared this on FB, and it blew my mind, guys. I am usually pretty adept at detecting myths and half-truths, but I have to admit that I've swallowed this one without question since childhood. I really recommend clicking the link and reading--it doesn't take long and has some very good information--but the upshot is this: there is no truth to the idea that if you pick up a baby bird and put it back in its nest, the mother will smell your touch on it and abandon it. If it's a nestling (baby bird, no real feathers, clearly not ready to fly), you should put it back in its nest. If it's a fledgling (real feathers, not fully grown but not a baby either), you should leave it be.
