The first five photos are of Nanday Parakeets and the last photo is of their nest in a power line pole. We can ID these parrots as Nanday Parakeets by their black heads and faces, mostly green plumage, bluish-green upper chests and long tails.
The Nanday Parakeet is native to South America, but due to release of caged birds there are self-sustaining populations in California, Texas and Florida. The ABA added this parakeet to its checklist in 2012.
The Nanday Parakeet is a new species to our Photographic Life List, which now stands at 518.
