We just talked about kites in the other non autistic forum I regularly post in. It was pointed out that the really down curved beak - you can see it better if you enlarge the photo - is characteristic of this group.Yes, they do do that, but there's no such bird as a firehawk. Never has been, never will be, it's not a word that's in our vocabulary. I can't write the most common name for them in this forum, but it rhymes with hithawk.
Also, they're not hawks, they're Kites. Mostly the Whistling Kite and the Black Kite but a few other smaller species have been known to do the same thing.

In Florida the Snail Kite feeds only on apple snails, a swamp dwelling creature. As the environment is degraded as to reduce the population of apple snails, so goes the snail kites.
Nice photo, Outdated.
