This happens all the time for me. I look around, 2 birds go into this tree, I go find the nest. But today is cool. I found 3 bird nests in the same tree. Since my mom is an ornithologist, we feel very strongly about birds and love to find them. We have a mourning dove that comes here every year to sit on her nest. Every year. Then, I just noticed, we have some late birds. I should add that this is literally 3 feet from my head. I could practically touch her. The late birds are House Finches. Then, we have an unknown bird (haven't seen it yet) nest that is literally 2 feet away. All in the same bush. AND THEN, we have a Hibiscus Tree with a Wrentit Nest in it. Then on the other side, not 15 feet away, we have an Allens Hummingbird pair. I should note it is an Allens Hummingbird Mom, and maybe Anna's Hummingbird father. That nest is 3 feet off the ground. Final nest, I swear. We have a Kestrel Nest in a Palm Tree in the neighbors front yard. And then we have cats. We keep them in for months on end to protect the babies. Let's hear about some nests you found around the house. Can anyone beat my nest record? Ill get pics of the nests later. Oh! We suspect the unknown nest to be some kind of Oriole based on the size and the way they built it.
