Pohnpei Lorikeet
Trichoglossus rubiginosus
Beautiful dark maroon parrot with a bright orange bill and yellowish tail. Found solely on the island of Pohnpei in the eastern Caroline Islands, where it is the only naturally-occurring parrot. Found in forested areas, both pristine and near human habitation and cultivation. Chatters shrilly and harshly; also gives a high slurred whistle.
Pale-vented Bush-hen
Amaurornis moluccana
Very secretive medium-sized rail that inhabits dense vegetation around wetland habitats in northern and northeastern Australia. Rarely seen away from cover. Dull gray-blue body, brown wings and tail, with reddish-brown undertail, yellow-green bill with small shield, and long yellow legs. Gives a variety of calls, usually a loud, repeated, squawky "wark-wark-wark" or an agitated "wark-woop, wark-woop, wark-woop."
Udzungwa Partridge
Xenoperdix udzungwensis
An unusual forest-dwelling partridge with a tiny range in the mountains of central Tanzania. The back is brown and barred, the underparts are gray with black scallops, and the bill is red. Found very locally in montane forest, especially in steep areas with bamboo. Somewhat similar to Scaly Francolin, but separated by smaller size and far more colorful markings. Most often detected by call: a repeated “kur-kur-kree” chant.
