Speckled Boobook

A typical thrush in shape and size, but with unusual brown coloration. Varies significantly across the three islands where it occurs, and these populations may be full species. The Grand Comoro birds have plain pale brown underparts, the Moheli birds have darker blotching below, and the distinctive Anjouan birds are scaled on the underparts. Found in humid forest, secondary habitats, and plantations, mostly at higher elevations, though down to sea level in some places. The song is a typical thrush mix of whistles and quavering notes, whose exact structure varies on the different islands. Also gives “pik” notes, short trills, and a high-pitched “seet.”  

Rather variable little flycatcher, easily identified in southern South America (where no similar species occur), but looks similar to several other elaenia species farther north. Common summer resident in forest, woodland, and matorral with taller trees. Note white-based crest, narrow white eyering, and whitish wingbars. A population in the deserts of northern Chile and Peru with spikier crest and duller wingbars is a common resident in scrub and farmland with taller trees. Another population in the Andes from Bolivia to Ecuador has a weaker crest where the white base is sometimes concealed. Populations are vocally distinct, and may represent separate species.

Large and rather uncommon tanager found in the canopy of humid forests where it usually accompanies mixed-species flocks. Plain brown overall with a cinnamon face, wings, and tail and a dark mask running through the eyes. Its plumage mimics the Buff-fronted Foliage-gleaner, with which it is easily confused and it may even occur in the same flock, but note the tanager’s thicker bill. The thin rising song is very high-pitched.
