The sombre hummingbird (Eupetomena cirrochloris) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Brazil. The sombre hummingbird was formerly placed in the genus Aphantochroa which was itself sometimes merged into Campylopterus. Based primarily on a molecular phylogenetic study published in 2014, Aphantochroa was merged by most taxonomic systems into Eupetomena. However, BirdLife International's Handbook of the Birds of the World retains it in Aphantochroa.
The sombre hummingbird is monotypic. The sombre hummingbird is about 12 cm (4.7 in) long and weighs about 7.1 to 9 g (0.25 to 0.32 oz). The sexes are essentially the same though the female is slightly smaller than the male. They have a slightly decurved black bill. Their upperparts are bronzy green to blackish bronzy green with a coppery sheen to the uppertail coverts. Their underparts are dull gray with a few dull green spots on the throat. Their tail is square; its central feathers are shiny green and the rest black with a bronzy gloss.
The sombre hummingbird is found in eastern Brazil from Pernambuco... Wikipedia →

Likely
About 50% of wildlife watchers report a Sombre Hummingbird sighting in Serra dos Órgãos National Park on a given day, based on 305 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 336 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 70% of wildlife watchers report a Sombre Hummingbird in Serra dos Órgãos National Park on a given day, against about 40% in October to December, the lowest months. That is one of Serra dos Órgãos National Park's driest months, with about 50 mm of rain against 310 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Sombre Hummingbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Serra dos Órgãos National Park, in our data
Serra dos Órgãos National Park is the only park on Wallace's Line with enough records to rate Sombre Hummingbird sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sombre Hummingbird is recorded against all the birds logged in Serra dos Órgãos National Park (305 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.
