Found some info on the bird in the pics, although classed as an eagle its name is a Snail Kite:
Abundant in Latin America, Snail Kites in the U.S. are only found in Florida and are highly endangered.
Also called the Everglades Kite, they are one of the most specialized of all hawks. They feed almost exclusively on the apple snail.
Fewer than 900 birds and 400 mated pairs were recorded in 2007. When they were listed as endangered in 1967, there were fewer than 100 individuals; their population peaked in 1999 at around 3600
