What defines a "feeder" bird, really? To me, a "feeder" bird is a bird that comes to food that you've put out for the purpose of attracting birds. A few years ago, we were able to log Snow Buntings (Plectrophenax nivalis) as feeder birds on our property because we put corn out along our driveway and they showed up to feed on it.
In this sense, our friends Eric and Dawn Scarborough recently had some pretty interesting "feeder" birds at their property in Starke County, Indiana. Knowing that raptors often feed on animal carcasses, they put a raccoon carcass in an agricultural field and set up a trail camera to capture the results. Here are some of their photos of one of the two Bald Eagles (Haliaeetus leucocephalus) and two Red-tailed Hawks (Buteo jamaicensis) that feasted on the remains.
