Mouse-gray Flycatcher
Myiophobus crypterythrus
Small, dull-colored flycatcher fond of lightly wooded areas, dry savanna, and forest edge. Its brownish-gray plumage, streaky breast, and buffy wingbars separate it from other similar species. Song is a quick “swee-ch-ch-ch-ch-ch…”; also gives a series of well-spaced whistles. Usually seen alone or in pairs, often sitting quietly on a low perch. Note its restricted range in far southwestern Colombia, western Ecuador, and northwestern Peru (mostly west of the Andes, but also in the Marañón Valley). Formerly considered a subspecies of Bran-colored Flycatcher.
识别特征
The Mouse-gray flycatcher is a small brownish-grey bird weighing 9.9g. It has a brown back, neck, and crown with a pale belly, throat, and supercilium and greyish-brown breast streaks and cheek. It's wings and tail are a darker brown with the coverts, the sides of the secondaries and tertials, and the tips of the primaries being a rufous color that varies from being a subtle tinge to a very bold ochre. It can be told from the Bran-colored by its darker sepia brown back and paler and more obvious supercilium. The related Rufescent flycatcher is easily differentiated by its rufous unstreaked belly and breast.
分类信息
The Mouse-gray flycatcher was originally described by English ornithologist Philip Sclater in 1861 from a specimen sent to him from Pallatanga, Ecuador. Sclater originally placed it in the genus Myiobius, but it was later placed in Myiophobus. Its specific epithet crypterythrus comes from the Greek crypto meaning hidden, and erythrus meaning reddish, a reference to its subtle reddish wing bars that aren't obviously apparent at first glance. Sclater noted its similarity to the Bran-colored flycatcher (then under the name Myiobius naevius) but identified its difference in size and morphology. It was later considered to be a subspecies of the Bran-colored flycatcher by Carl Eduard Hellmayr under the name Myiophobus fasciatus crypterythrus. Some publications used the name Western Banded Flycatcher for the subspecies during the 20th century. Although its distinct appearance was apparent, some believed that it didn't even warrant a subspecies, with Zimmer considering it conspecific with M. f. rufescens due to a confusing female specimen from where the ranges overlap. In 2023 a proposal to the South American Classification Committee by J.I. Areta and T.S. Schulenberg to split the subspecies M. f. crypterythrus and M. f. rusfescens from the Bran-colored flycatcher was approved unanimously, leading to the split of the Mouse-gray and Rufescent flycatchers as new species.

Unstreaked Tit-Tyrant
Uromyias agraphia
Small gray flycatcher with a simple, bold facial pattern. Has a brownish gray body with a black eyeline and crown and a white eyebrow; usually has very faint streaking through the face and breast. Looks big-headed and usually perches upright. Found around forest edges at high elevations, especially near the treeline and around patches of bamboo; often forages in groups and frequently associates with mixed-species flocks. Listen for its lisping high song and stuttered “peep” call notes.
Tapajos Antpitta
Myrmothera subcanescens
Retiring species, almost tailless with very long robust legs. Has a reddish brown-back and white underparts streaked olive-gray. Hops, or occasionally walks very quietly, on the ground of humid forest, normally close to fallen trees in dense undergrowth. Song is a haunting series of low hollow notes that increase in volume, audible from a long distance.
Forster's Tern
Sterna forsteri
Smaller than all the gulls, with thinner and more pointed bill. Distinguished from other terns by pale whitish wings and orange-based bill in summer, and isolated black ear patch in winter. Forages by circling and hovering over bays, ponds, and lakes, then dropping to snatch fish. Often rests on sandbars, piers, and other structures with other gull and tern species. Snappy, quick wingbeats and acrobatic in flight.
