Long-tailed parakeet, mostly green with a scaled breast; has a narrow blue forehead and lacks a red patch on edge of shoulders. Feeds in small groups in the canopy of both humid non-flooded and seasonally flooded forests, as well as forest edges. Most often seen fleetingly, flying in noisy flocks through the sub-canopy. The similar Painted Parakeet has a larger blue patch on the forehead and red shoulder patch. The calls of Painted and Santarem parakeets are apparently indistinguishable.
