October 3, 2022 - Green-tailed Warbler or Green-tailed Ground-Tanager (Microligea palustris)

Found in thickets and scrub in and around forests on the island of Hispaniola, these birds have been classified at various times as warblers, tanagers, or neither. They eat mostly insects, foraging in the undergrowth, alone, in pairs, or in mixed-species flocks. Breeding mostly between May and June, they build cup-shaped nests in shrubs, thickets, or cacti. Females lay clutches of two to four eggs.

The Green-Tailed Warbler is known  entirely from within the island of Hispaniola

Physical Description: Microligea, the Green-Tailed Warbler, is a small warbler - about 12 to 14.5 centimeters in length, a little smaller than a house sparrow. They have grey heads and white bellies, with green backs, wings, and tails. Their tails are fairly short, and a little more yellowish than the rest of the body. Both sexes are alike in coloration, and juveniles are slightly duller in color. They have short, pointed beaks. There is also a distinctive green crescent above the eye, which is reddish.

Diet: The Green-Tailed Warbler mainly feeds on insects and forages in the dense undergrowth and thickets close to the ground.

Behavior: These birds forage together in mixed-species flocks, though they are also known to travel alone, or in pairs. They do not migrate, but stay within their limited range year-round. They make a short, rasping, and squeaky call, and their song sounds like ‘sip sip sip’ repeatedly.

They breed from May to June in mountain environments, making nests out of a cup of vegetable material usually about 2 meters up from the ground, within shrubs and thicket. They lay about two to four green, spotted eggs, which hatch potentially within one month. The Green-Tailed Warbler then goes on to live for about seven years in total.

Ecosystem: The Green-Tailed Warbler primarily lives in mountain forests, especially pine and broadleaf forests, that feature dense understories. They are sometimes seen in semi-arid scrubland as well. Their babies are a major source of food for other animals; very few chicks survive to adulthood due to predation.

Other: Despite its restricted range, this bird is not threatened with extinction.
