Crocker Jungle Flycatcher

Rather large, dark, yellow-tailed bird of humid evergreen forest and edge in tropical lowlands. Where present, colonies of large pendulous nests adorn tall trees. Often in flocks, usually in forest canopy at fruiting trees. Male is much larger than female, but sexes look similar, with a dark, rich brown head and body, blackish upperparts, pale yellowish bill, and bold yellow tail sides. Flight much quicker than larger Montezuma Oropendola, with deep, rather swooping wingbeats that produce a rushing sound.

Green above with paler yellowish belly and long, pointed tail. Average size for a parakeet. Distinctive brown cheek and upper breast usually quite obvious; can be trickier to see in flight. Almost always in small flocks, which feed inconspicuously on fruit in gardens, forest edges, and second growth. More obvious in flight; listen for grating, squeaky calls.

Long known to ornithologists as something different (and informally called “Millpo Tapaculo”), this bird was finally described as a new species in 2020. It inhabits grassy, rock-strewn areas above tree line at high elevations in the eastern Andes of central Peru. Plumage is mainly gray with tan rear parts that are faintly barred, and it sometimes shows a faint, whitish eyebrow; female is browner than male. Similar in appearance to several other tapaculos, and best identified by range and voice. Song, often given from atop a rock, is a seemingly endless series of raspy chip notes.
