The azure-rumped tanager or Cabanis's tanager (Poecilostreptus cabanisi) is a species of bird in the family Thraupidae. It is a local resident in humid broadleaf forests and adjacent plantations of the Pacific slope of western Guatemala and southern Chiapas, Mexico. It has been reported at elevations of 850–1,900 m (2,790–6,230 ft).
Its plumage is mostly pale blue, with a purplish-blue crown, dark lores and lower auriculars, and distinctive dark spots across the chest. The mantle is mottled greenish-blue and black. The wings and tail are black with blue edgings. The bill is gray with a dark tip. Cabanis's tanagers utter several sibilant vocalizations, hard trills and twitters.
The azure-rumped tanager is omnivorous, feeding on fruit and arthropods. In Guatemala, abundance was positively correlated with the density of Ficus aurea trees. Figs of that tree are a main food source. The nesting season ranges from April to September, during which azure-rumped tanagers move in pairs or family groups. Cooperative breeding has been reported. Outside the breeding season, larger flocks of up to 18 birds have been reported.

With luck
About 10% of wildlife watchers report an Azure-rumped Tanager sighting in El Triunfo on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 160th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April and July
In those months about 30% of wildlife watchers report an Azure-rumped Tanager in El Triunfo on a given day, against under 5% in February and November–December, the lowest months. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Azure-rumped Tanager sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only El Triunfo, in our data
El Triunfo is the only park on Wallace's Line with enough records to rate Azure-rumped Tanager sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Thraupidae
The closest relatives of the Azure-rumped Tanager that you can see in El Triunfo (family Thraupidae, Tanagers and Allies) are Red-legged Honeycreeper (about 50%), Yellow-winged Tanager (about 50%) and Black-headed Saltator (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Azure-rumped Tanager is recorded against all the birds logged in El Triunfo (29 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
