Distinguishing Characteristics

Becards (Pachyramphus) have relatively large heads and heavy bills, and resemble tyrant flycatchers (Tyrannidae). Male becards also have modified wing feathers: the ninth primary is very short (half the length of the 10th primary), and is sharply pointed. Pink-throated Becard is one of the larger species of Pachyramphus becard. The male is predominately dark gray, with a patch of dark pink on the lower throat. The female is dull brown above, with a gray crown and back, rufous tail and rufous-edged wing feathers, and is cinnamon below.

Similar Species

Male Pink-throated Becard is distinctive in most of Amazonia; the combination of dark gray plumage and pink lower throat are unique within its range. The most similar species are three other large Pachyramphus, with distributions that are allopatric or only narrowly sympatric Pink-throated Becard. Crested Becard (Pachyramphus validus) is locally sympatric with Pink-throated Becard, in eastern and southern Amazonia. Male Crested Becard is paler gray below, appearing two-toned, and lacks the pink throat. Female Crested Becard is more similar to female Pink-throated, but has a rufous back, showing greater contrast to the gray crown.

Among allopatric becards, male One-colored Becard (Pachyramphus homochrous) of northwestern South America and Panama is all gray, with no pink on the throat; the female is mostly rufous and buff, including on the crown. Male Rose-throated Becard (Pachyramphus aglaiae) of Central America has a pattern similar to that of male Pink-throated Becard, but in most subspecies, male Pink-throated is much paler gray than Pink-throated, and has a larger, paler pink throat patch. Females of the two species also are similar, but among other differences, female Pink-throated Becard has a blacker crown.

Confusion may also arise with White-winged Becard (Pachyramphus polycopterus), which is widely sympatric with Pink-throated Becard. Males of White-winged Becard, in subspecies sympatric with Pink-throated, are gray below, but show at least some white in the wing, and more extensive white in the tail. White-winged Becard also is smaller than Pink-throated Becard.

Detailed Description

The following description is based on Mobley (2004):

Adult male: Mostly black or dark sooty gray, face slightly paler grayish black. Slightly paler below. Patch of pink (sometimes indistinct) on lower throat and upper breast. Some white along bend of wing (but usually hidden). The ninth primary is very short (half the length of the 10th primary), and is sharply pointed.

Adult female: Crown and nape grayish brown. Small buff supraloral spot. Back gray; rump gray with a rufous tinge. Wings and tail rufous. Underparts, including throat, buff. Plumage of the female is reported to be individually variable (Hellmayr 1929, Friedmann 1948).
