Tangara Collirroja

Identificación

Crimson-collared tanagers average 19–20 cm (7.5–8 in) long. The adult plumage is black with a red collar covering the nape, neck, and breast (remarkably similar to the pattern of the male crimson-collared grosbeak). All tail coverts are also red. The bill is striking pale blue and the legs are blue-gray. In adults, the irides are crimson, contrary to what is shown in Howell and Webb. Females average slightly duller than males, but are sometimes indistinguishable from them. Juvenile birds are similar except that the hood is dull red, the black areas are tinged with brown, and the breast is mottled red and black. Young birds also have a duller bill color.<p>Vocalizations are high-pitched and sibilant. There are several calls; one rendered as ssii-p is given both when perched and in flight. The song is jerky and consists of two-to-four-note phrases separated by pauses, tueee-teew, chu-chee-wee-chu, teweee.

Taxonomía

This species is sometimes placed in a genus of its own as Phlogothraupis sanguinolenta, and a genetic study suggests that it is less closely related to the other Ramphocelus tanagers than they are to each other. Its closest relative is the masked crimson tanager.[citation needed]

Resident species

Comportamiento

The nest is a cup built of such materials as moss, rootlets and strips of large leaves such as banana or Heliconia[citation needed], and is placed at middle height in a tree at a forest edge. The female usually lays two eggs, pale blue with blackish spots.<p>Because the species is not threatened, the population size is very large and the trend appears to be stable, the species is evaluated as Least Concern.
