SPECIES

Golden-hooded Tanager Tangara larvata

Version: 1.0 — Published October 5, 2010

Appearance

Distinguishing Characteristics

The Golden-hooded Tanager is distinguished by its golden hood for which it gets its name. Other prominent features include a black and blue mask, a broad black breast band and black back, and bright blue flanks and rump.

Similar Species

The Golden-hooded Tanager is most similar to the Masked Tanager (Tangara nigrocincta) and the Blue-necked Tanager (Tangara cyanicollis), but each species is distinctive. The bright gold hood allows the Golden-hooded Tanager to be distinguished easily from the other two species, both of which have hoods that are entirely blue. There also is no geographic overlap between the Golden-hooded Tanager and the Masked Tanager, which occurs only east of the Andes. The distributions of Golden-hooded and Blue-necked tanagers, however, do overlap in western Colombia and Ecuador.

Detailed Description

Adults: Sexes are similar. The following description is based on Ridgway (1902), and refers to nominate larvata; see Geographic Variation for characters of the three other subspecies.


Adult male: Anterior portion of forehead and the malars, and the lores, chin, and ring around the eye, black. Posterior region of the forehead and the malars, the area below the eyes, and most of the auriculars, light bluish violet. Crown, nape, and sides of neck golden buff; the perception of this color is variable, depending upon the angle of the light, ranging from deep orange-buff to oil green. Back, scapulars, upper breast, and sides of breast black. Rump glossy light blue; uppertail coverts black, broadly margined with light bluish green. Lesser and median wing coverts bluish violet ; greater wing coverts black, margined with light blue and greenish. Remiges and rectrices black, margined with light yellowish green, the margins buffier on the tertials. Center of lower breast, and the belly, white. Flanks bluish violet, becoming light greenish blue posteriorly. Crissum and undertail coverts pale buffy.

Adult female: Very similar to the male, "and apparently not always distinguishable, but usually slightly duller in coloration."


Juvenile: Lores, eye ring, anterior portion of the malars, and chin dusky. Rest of head and and neck dull light green, each feather with a small central dusky spot. Back dull dusky greenish, with a blackish patch on each side of the back. Lower back and rump dull greenish. Lesser wing coverts dull light greenish blue. Median wing coverts dull light bluish green, with dusky bases. Rest of wing and tail dusky, feathers with yellowish green margins. Throat, center of breast, and belly dull whitish, with a slight yellow tinge. Sides of breast greenish dusky. Flanks dull grayish, becoming buffier on lower flanks. Crissum and undertail coverts pale buffy.

Molts

Little information. Generally, Tangara are believed to attain definitive plumage following the preformative molt, and the preformative molt may be only a partial molt (Ryder and Wolfe 2009). But molts in Tangara in general are very poorly known, and apparently have not been studied in the Golden-hooded Tanager.
