Puerto Rican Tanager

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.

A small bird with a long tail that is held cocked. Its tail is usually blue (except in juveniles, which have brown tails). Breeding males have a pale blue crown, cheek, and back with a strong black line from the bill through the eyes and around the back of the head. Nonbreeding males are fairly plain grayish-brown birds with black bills and bright blue tails. Females have a duller blue tail and a reddish bill. Note that the patch between the eye and bill (lores) on females is a reddish color of about the same tone as the bill (in Variegated and Purple-backed Fairywrens the lores are much darker than the bill). Female Superb Fairywrens have a much cooler and grayer plumage than the warm tones of Red-backed Fairywren. This species is abundant in parks, gardens, and open woodlands around much of southeastern Australia.

Very small, with a distinctive short, rounded tail with conspicuous spots at the tip. Body sandy-colored below, streaky above. Breeding males have a dark bill and crown. Found in open grasslands, meadows, marshes, and agricultural areas. Most readily detected by its repetitive and monotonous song, given from either a perch or in an undulating song flight. Song varies across wide distribution, ranging from evenly-paced squeaky “tsik, tsik” of African and European birds to the fast dry ticking of Southeast Asian birds.
