The yellow-headed blackbird (Xanthocephalus xanthocephalus) is a medium-sized blackbird with a yellow head. It is the only member of the genus Xanthocephalus. Their scientific name derives from the Greek word for yellow, xanthous, and the word for head, cephalus.
Yellow-headed blackbirds are relatively large blackbirds with large, yellow heads. They measure 8.3–10.2 in (21–26 cm) in length, with a wingspan of 16.5–17.3 in (42–44 cm) and a weight of 1.6–3.5 oz (44–100 g). Adults have a pointed bill. The adult male is mainly black with a yellow head and breast; they have a white wing patch sometimes only visible in flight. The adult female is mainly brown with a dull yellow throat and breast. Immature members of both sexes are brown with duller yellow plumage compared to adult males. Immature males also have some white patches on the wing. Both sexes resemble the respective sexes of the smaller yellow-hooded blackbird of South America.

Rare
Under 5% of wildlife watchers report a Yellow-headed Blackbird sighting in Big Bend National Park on a given day, based on 271 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 128th most-seen of the 270 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–May and July–October
In those months about 10% of wildlife watchers report a Yellow-headed Blackbird in Big Bend National Park on a given day, against under 5% in June and November–March, the lowest months.

Across all the parks we cover, that three-hour window holds the most Yellow-headed Blackbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 22
Of the 22 parks where we can rate Yellow-headed Blackbird sightings, Big Bend National Park ranks 6th at under 5%. The best odds are in Yellowstone National Park (United States, about 20%), Death Valley National Park (United States, about 10%) and Badlands National Park (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the Yellow-headed Blackbird is recorded against all the birds logged in Big Bend National Park (271 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.
