The first Brazilian specimens of Yellow- cheeked Becard Pachyramphus xanthogenys, from the state of Acre, compared to specimens of Green- backed Becard P. v. viridis, from Mato Grosso do Sul and Minas Gerais. (a) Lateral view. Top to bottom: 1) P. xanthogenys, male (MPEG 58925); 2) P. V. viridis, male (MPEG 41284).

(a) Lateral view. Top to bottom: 1) P. xanthogenys, male (MPEG 58925); 2) P. V. viridis, male (MPEG 41284). Note the bright golden-yellow cheeks and throat, absence of a grey nuchal collar, and greyish-white (not creamy) belly of the male P. xanthogenys. (b) Dorsal view. Left to right: 1) P. xanthogenys, presumed female (MPEG 61447); 2) P. xanthogenys, male (MPEG 58925); 3) P. V. viridis, female (MPEG 51850); and 4) P. v. viridis, male (MPEG 41284). Note the nearly uniform ash- grey crown, hindneck and nape of the presumed female P. xanthogenys. The dull greenish line extending back from the eye is barely visible here. Note also the well-defined grey nuchal collar in both the P. V. viridis. (c) Lateral view. Left to right: 1) P. xanthogenys, presumed female (MPEG 61447); 2) P. xanthogenys, male (MPEG 58925); 3) P. v. viridis, female (MPEG 51850); and 4) P. v. viridis, male (MPEG 41284). The differences in ventral color (whitish grey in xanthogenys; creamy white in viridis) can be seen here. Note also the near- complete lack of rufous on the upperwing-coverts of the presumed female P. xanthogenys; otherwise, this specimen matches well the description of the P. x. peruanus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Ornithologists' Club.
