Just what do you suppose preys on song birds? Here is one of them that we saw in our closest oak tree at dusk.
A cooper hawk is only one of many birds of prey in our area ( Osprey, Red-tailed hawk, Barred Owl). But more song birds die in migration due to windows, windmills and house cats than predators. Some birders use cutouts of hawks or owls or tape on their windows for prevention. Keeping your cats in during spring migration is helpful too.
This Cooper's Hawk flew into our oak tree close to the feeders. He did not go after any birds on the deck but flew off. Later the Cooper flew between our house and the trees. In our yard were Goldfinch House Finch, Chipping Sparrows, Blue Jays, Nuthatches, Chickadees, Rose-breasted Grosbeaks, Yellow- rumped and Connecticut Warblers and woodpeckers.
So he could choose from a large varied menu. I am pretty sure there were other warbles but I could not ID them. It was twilight and misting at the time of the photos.
