Occurs in numerous protected areas in Amazonia, where pristine habitats are unprotected, but remains little immediate risk. Uncommon to locally fairly common in Amazonia. Voice: Calls during foraging high, thin, rapid bursts of ‘sit’ and ‘tschip’, often 5-6 in a series. Animalia: information (1) Animalia: pictures (22861) Animalia: specimens. May spend longer periods of time with mixed flocks containing insectivores during midday, then searching for arthropod prey by hopping along large canopy branches and peering, head down, first on one side and then on the other in almost mechanical matter as it progresses onward, or checking epiphytes or debris accumulated on limbs in canopy or sub canopy.īreeding: Eggs reported as being grayish- white, thickly dotted with darker shades of grey. Feed in pairs or small groups moving in and out of canopy in mixed species flocks, often leaving to join faster moving associations and other T angara at fruiting trees, or to rest in emergent trees. Forages for insects by searching under larger limbs and inspecting epiphytes. Generally found in small groups with behavior like many other lowland Tangara.įood: Fruits and arthropods. Prefers canopy and borders of humid forest in lowlands to 500 m, rarely higher. Less often found in forest borders, tall second growth, and trees in clearings.
Habitat: Found in treetops in humid terra firme and varzae forests.
#OPAL RUMPED TANAGER SERIES#
Calls are indistinct chips, often given in rapid series in flight. The shining white rump can be seen from most angles on perched birds, even when high overhead. Juvenile dull and essentially featureless. The opal rumped tanager is best identified by uniform dark underparts with rufous lower belly and undertail coverts, and active behavior.
Sexes similar or female slightly duller than male. Iris dark brown bill black legs dark gray to blackish. Lower breast, belly and under tail coverts contrasting rich dark chestnut. Compared to the similar Opal-rumped Tanager, this species has a distinctive whitish crown and a blue (not reddish) belly the latter can be helpful for identification from below as it moves through the canopy with mixed species tanager flocks. Mid-breast and sides shining violet blue. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager. It is found in the Amazon and Atlantic Forest of South America. Black band across throat and upper chest. Tangara velia The opal-rumped tanager is a species of bird in the family Thraupidae. Forehead, side of head and side of neck medium blue. Primary coverts flight feathers and tertials narrowly edged greenish blue. Dutch: Opaalstuittangare: English (United States) Opal-rumped Tanager: French: Calliste. Feathers of median coverts rounded and broadly tipped greenish blue. Species names in all available languages. Upper tail- coverts opalescent blue, tail black, feathers narrowly edged blue. Rump glistening opalescent yellowish to straw to greenish (varies with light).
Dark plumage with marked geographical variation in plumage. It is therefore suspected to decline by <25% over three generations.Range: Guianas and northern Brazil, northern Amazon (from Rio Negro to eastern Paraguay)ĭescription: 12 to 14 cm in length, 19 to 23g. Trend justification Prior to being split, this species was suspected to lose 11.6-12.9% of suitable habitat within its distribution over three generations (15 years) based on a model of Amazonian deforestation (Soares-Filho et al.
Population justification The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. For these reasons the species is evaluated as Least Concern. The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). Justification of Red List Category This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations).
