Thamnornis
Thamnornis chloropetoides
Odd, warbler-like, long-tailed and long-billed tetraka. Madagascar endemic that is the only tetraka regularly found in spiny forest. Mostly skulks in the understory, but will sing from an open perch at the top of a tree. Song is a sputtering trill that is sometimes followed by a series of lower “chup” notes. Larger, longer-tailed, and longer-billed than jeries. More greenish than Subdesert Brush Warbler, with white tips to the tail, and without fuzzy breast streaks.
Identification
The thamnornis or thamnornis warbler (Thamnornis chloropetoides) is a species of Malagasy warbler in the family Bernieridae. It is endemic to Madagascar, where it is restricted to the spiny forest of the island's southwest. It is greyish above and whitish below, with narrow green fringes to the wing feathers and a marked supercilium. The outer tail-feathers have pale tips. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is usually seen near the ground, but sings from tall trees. It often associates in family groups or with Newtonias in mixed-species flocks. While not considered threatened, its population is inferred to be decreasing due to widespread deforestation across its range. A 2019 phylogenetic study found the Thamnornis to be the sister species of Rand's warbler.

Andean Parakeet
Bolborhynchus orbygnesius
Small green parakeet with a yellow wash in the face and a gray bill. Found at high elevations in intermontane valleys, around semi-humid scrub and forest. Compared to the similar Mountain Parakeet, Andean has a shorter tail, a gray bill (not pale pink), and very little blue on the wing. Its calls are given in rapid series, sounding like a chuckled “juh-juh-juh.”
Rufous-banded Honeyeater
Conopophila albogularis
Small honeyeater with white throat and orange-red breast band. Face is gray, back is brown, and belly is white. Feeds on insects and nectar in woodlands, often near water. Also found in mangroves. Juveniles lack the rusty breast band and also have pink on the bill. Found at lower altitudes in northern Australia and New Guinea. This species is abundant in parks and gardens in Darwin.
Malabar Flameback
Chrysocolaptes socialis
A large, crested woodpecker with a golden-olive back endemic to wet lowland and foothill forests in southwestern India. Separated from Common Flameback and other “small-billed” flamebacks by a much larger bill, a mottled black-and-white nape instead of a black nape, and a divided black horizontal stripe below the cheek. Separated from the similarly large-billed White-naped Woodpecker by the less clean-cut face pattern, a red rump, the lack of a clean white nape, and a preference for wetter habitat. A loose participant in mixed-species foraging flocks, often detected by its loud, high-pitched trill similar to that of Common Flameback.
