Black vultures live year round as north as Pennsylvania and as south as Patagonia. They are frequently in large groups, have a black bald head, and white wing patches that can be tough to see. They are raptors as you know, and like all vultures are usually scavenging and eating carcasses (someone's gotta do it!).

Thanks for all the guesses! When I first saw the photo Max sent, my first thought was double-crested cormorant because it's the only bird I've ever seen sitting and drying their wings out, but the neck looked too short to be a cormorant. With more research I found out that anhingas and vultures also do this behavior, so then asked if the birds appeared bald. Max did some sleuthing on his own and on ebirds.org found out that someone else had seen a large group of black vultures in the same area and this confirmed our identification.
