The blue-billed curassow (Crax alberti) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is endemic to Colombia. The blue-billed curassow is monotypic. However, it formerly included what is now the yellow-knobbed curassow (Crax daubentoni) as a subspecies. The holotype of putative species C. annulata has been determined to be a female blue-billed curassow.
The blue-billed curassow is 82.5 to 92.5 cm (2.7 to 3.0 ft) long and weighs 3.2 to 3.6 kg (7.1 to 7.9 lb). It is the only curassow with a blue cere and wattle, the latter found only on the male. Males are mostly black with a white vent and tail tip. Females are also mostly black but their lower belly and vent are rufous. They have fine white barring on the wings and tail, and a rare "barred" morph also has barring on the breast and belly. Both sexes have an erectile crest, the male's black and the female's black and white.
The blue-billed curassow is found only in northern Colombia. Its range used to stretch 106,700-square-kilometers; it now has a highly fragmented range, with small populations between La Guajira and... Wikipedia →

With luck
About 10% of wildlife watchers report a Blue-knobbed Curassow sighting in Tayrona National Natural Park on a given day, based on 193 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 72nd most-seen of the 285 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.
March and April
In those months about 30% of wildlife watchers report a Blue-knobbed Curassow in Tayrona National Natural Park on a given day, against under 5% in February and November, the lowest months. Those are among Tayrona National Natural Park's driest months, with about 25 mm of rain a month against 180 mm in October.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Blue-knobbed Curassow 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 Tayrona National Natural Park, in our data
Tayrona National Natural Park is the only park on Wallace's Line with enough records to rate Blue-knobbed Curassow sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blue-knobbed Curassow is recorded against all the birds logged in Tayrona National Natural Park (193 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.
