The Plumbeous Kite (Ictinia plumbea) is pretty similar to the Mississipi Kite, differs mainly by the inner webs of the primaries being a deep chestnut rufous. They are migratory here in my region (São Paulo State), arriving in September and leaving around March. They come to breed here and to take advantage of an abundance of flying insects, specially cicadas and flying ants. Insects represent over 95% of prey items, with few snakes and snails also reported. Often gather in pretty large flocks during insect swarms.They can be found in a variety of habitats, but usually avoid extensive forest, except during migration, when flocks may be found near large rivers in the Amazon.
