Spot-tailed Antwren

Herpsilochmus sticturus

Small antbird of rainforest canopy; somewhat more common in forests with sandy soils. From below, note clean white underparts and heavy bill. Usually encountered with mixed-species flocks. Forages slowly along limbs and explores leaf clusters. Very similar to Todd’s Antwren and most safely separated from that species by voice. Song is an accelerating “bouncing ball” series, similar to Pygmy Antwren but with a harder quality and not falling in pitch at the end.

Song Thrush

Song Thrush

Turdus philomelos

Plumage brown above and whitish below with droplet-shaped dark spots; breast has rich buffy wash in fresh plumage (mainly autumn–winter). Appreciably smaller, darker overall, and more compact than Mistle Thrush. An inhabitant of wooded habitats, including parks, gardens, and farmland with hedges and taller trees; often feeds on lawns and grassy verges, but usually near cover. Strident song, often heard in suburban neighborhoods, is more prolonged than that of Eurasian Blackbird, and frequently repeats phrases 2-4 times. A native of Eurasia, introduced to southeastern Australia, New Zealand, and a few surrounding islands.

Slaty Egret

Slaty Egret

Egretta vinaceigula

A small, dark egret with a rusty-buff throat and yellow-green legs and feet. It occurs solitarily or in small groups, preferring marshes and floodplains; it avoids open areas, seeking cover in small channels or near long grass. Slaty Egrets walk slowly, shuffling their feet to surprise fish and frogs. Although it is mostly resident, it can disperse widely outside of its core range. The similar Black Egret differs by having a dark throat, dark legs with yellow feet, and occasionally foraging in a distinctive “umbrella” position, whereby it covers its head with its wings.

Solomons Island-Thrush

Solomons Island-Thrush

Turdus kulambangrae
