Nightingale Island Finch Nesospiza questi

A small lemon-olive finch with a gray patch in front of the eye. Female is smaller, duller, and streakier than the male. Juvenile resembles female but is browner and streakier. An abundant endemic throughout Nightingale Island and small adjacent islands, preferring tussock grass. Male’s song is high-pitched and sharp, an often repeated “wheet-whuu”; female answers with a whistle. The much larger and rarer Wilkins’s Finch has a deep grosbeak-like bill and a slower song, and is more restricted to wooded parts of the island than Nightingale Island Finch.
