Gansu Leaf Warbler
Phylloscopus kansuensis
Small, confusing leaf warbler with olive-yellow upperparts, yellow brow, double wing bars, and a pale crown stripe. Extremely similar to many other small leaf warblers: Pallas’s Leaf Warbler has a brighter yellow brow stripe, and Chinese Leaf Warbler has an incrementally weaker head pattern and a small hook at the rear end of the black eye stripe. Lemon-rumped Warbler is extremely similar visually but averages paler on the brow stripe and darker on the underparts. Listen for the song, an accelerating series of sharp chips followed by a trill; its calls include a tinkling series of chips. Inhabits mid-altitude forests, usually bushy poplar and birch groves; found at lower altitudes than Chinese Leaf Warbler.
Torresian Crow
Corvus orru
Australian crows and ravens are challenging to identify; concentrate on call, throat-hackles, behavior, and location. Calls include fairly short, repeated “ah-ah-ah” and a unique rattling croaking. Throat hackles can look impressive, leading to confusion with ravens. Inhabits many habitats in northern two-thirds of Australia and in New Guinea. The default crow/raven of Darwin, Cairns, and Brisbane.
Least Pygmy-Owl
Glaucidium minutissimum
Very small rufous owl with white spots flecked on rich brown head, a white belly streaked with rufous and white spots on the back. Similar to Ferruginous Pygmy-Owl, which has a streaked rather than spotted head and a longer tail. Found in the canopy of humid forest and forest edges. The song is a series of two-three high-pitched whistles.
