Nanday's are medium-sized parakeets. The black head and green body are the basic identifiers, but they also have a tinge of blue in the chest and wings, and bright, reddish-orange "cuffs" on their legs. The species is native to South America but have established self-sustaining populations in some areas of Florida.
Tree Swallows are streamlined small songbirds with long, pointed wings and a short, squared or slightly notched tail. Their bills are very short and flat. Foraging flocks are frequently seen over wetlands, water, and agricultural fields.
