Palm Tanager

Thraupis palmarum

Large, plain tanager, gray overall with hints of olive-green in good light; note contrasting black wings with paler patch at base of primaries. A habitat generalist often found around palm trees and in open shrubby areas, gardens, and forest edges. Usually in pairs or small flocks, sometimes with other species. Often quite noisy and conspicuous; gives a series of sputtering squeaks or a single nasal “swee?”

Cassia Crossbill

Cassia Crossbill

Loxia sinesciuris

Stocky, large-headed finch with unique crossed bill used to pry seeds out of lodgepole pine cones. Similar to Red Crossbill, best separated by voice, specifically the flight calls given in flight, a comparatively lower frequency, dry "dip-dip-dip". Endemic to Albion Mountains and South Hills of southern Idaho. Males are dull red or orange overall with gray or brown highlights. Females are dull olive-yellow. Immatures are streakier than adults. Sedentary, unlike most other crossbills. Often in small flocks. Rarely visits feeders.

Madagascar Harrier-Hawk

Madagascar Harrier-Hawk

Polyboroides radiatus

Large gray raptor with black wings and tail. There is a single white band through the tail and bare skin around the face that is normally yellow but which can flush bright red. Immature is brown, with a pale head and pale fringes on the wing that separate it from all other brown raptors in its range. Endemic to Madagascar, and found in a variety of habitats, including forest, scrub, and savannah. Absent from pure grassland and from the high mountains. Often soars. Call is a long, high whistle, often given in flight. 

Pale-breasted Illadopsis

Pale-breasted Illadopsis

Illadopsis rufipennis

A chunky, mid-sized, remarkably drab babbler with a white throat and brownish breast. Found in the understory of rainforest at low and middle elevations, usually in small groups. Shy and skulking; rarely seen unless searched for. Very similar to Brown Illadopsis, but slightly different vocally, with higher and more inflected whistles. Also slightly paler below and more richly colored above, with a cleaner white throat. Most often detected by voice. The highly variable song consists of single-note pure whistles or short whistled phrases separated by pauses, often in a three-note ascending series; listen for a haunting clear monotone whistle. Also gives scolding calls, sometimes accompanying the whistled song.
