Taxonomy and systematics

The genus ''Granatellus'' was traditionally placed in family Parulidae, the New World warblers. Studies of DNA sequences in the early 2000s resulted in its being moved to its present family. The rose-breasted chat and the other two members of its genus, red-breasted chat (''G. venustus'') and grey-throated chat (''G. sallaei'') form a superspecies.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B. Robbins, F. G. Stiles, and K. J. Zimmer. Version 19 January 2021. A classification of the bird species of South America. American Ornithological Society. https://www.museum.lsu.edu/~Remsen/SACCBaseline.htm retrieved January 19, 2021 The rose-breasted chat has two subspecies, the nominate ''Granatellus pelzelni pelzelni'' and ''G. p. paraensis''. The latter might be a species in its own right ("rose-bellied chat"), based on differences in plumage and vocalizations from the nominate.

Description

The nominate rose-breasted chat is long and weighs . The male has a black head with a white

supercilium The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also ...

, blue-gray upperparts, and a black tail. Its throat is white with a thin black line separating it from the rose-red breast, belly, and vent area. It has white flanks separating the blue-gray and red. The female's crown, nape, and upperparts are blue-gray and the tail black. Its face, breast, flanks, and vent are a rich buff and its throat and belly are white. The male ''G. p. paraensis'' is also long. Its plumage differs from the nominate's in that its head is gray except for the forecrown, its underparts are a deeper red, and the white of the flanks is much reduced or absent. The female is essentially identical to the nominate.

Distribution and habitat

The nominate rose-breasted chat is found in extreme eastern Colombia east through southern and southeastern Venezuela and

. The nominate's range is mostly at low elevation but reaches as high as in southern Venezuela. ''G. p. paraensis''s range is almost entirely at very low elevation.

Behavior

Feeding

The nominate rose-breasted chat's diet is thought to be mostly or entirely insects and other invertebrates. It forages mostly at middle to high levels but sometimes in the understory; it gleans foliage and sallies out to catch flying insects. In the non-breeding season it may join

except that a nominate male was in breeding condition when collected in January and a nominate juvenile was observed in molt in early May.

Vocalization

The nominate rose-breasted chat's song is " a series of 5–6 clear, sweet notes on one pitch". Its calls include a repeated "jrrt". ''G. p. paraensis''s song is alternating "mellow low-pitched downslurred whistles and harsher short high-pitched notes".

Status

has assessed both subspecies of rose-breasted chat as being of Least Concern. "No population estimates f the nominate areavailable, but known from a number of protected areas." However, ''G. p. paraensis'' "is suspected to lose 22–25% of suitable habitat within its distribution over three generations (12 years)".
