Yellow-Headed Blackbird or Red-Winged Blackbird?
Here's how to tell the difference
Yellow-Headed Blackbird
Red-Winged Blackbird
Yellow-Headed Blackbird
Xanthocephalus xanthocephalus
General appearance
The Yellow-headed Blackbird is about the size of a Robin, ranging from 20-28 cm in size. It possesses broad, rounded wings with a rounded, square-tipped tail. Coloration includes black, brown, white, and yellow. Notably, wing patches, which are obvious in flight, are white.
Male vs female
Males and females of this species exhibit distinct differences. Males are predominately black, but their heads stand out due to their bright yellow coloring, a feature not seen in any other species. Females, a bit smaller than males, are generally of a sooty brown color, with the exception of yellow areas on the face and chest. They also have white streaks on their belly, but do not possess the male's white wing patches.
Juvenile
Immature Yellow-headed Blackbirds, or juveniles, share some similarities with adults but lack the striking differentiation between black and yellow seen in adults. They have some yellow coloring on their heads, and their wing patches, whilst present, are smaller or altogether absent compared to the adults.

Agelaius phoeniceus
General appearance
The Red-winged Blackbird's general size ranges between 7 to 9 1/2 inches (18-24 cm). Its wings are broad and rounded with a rounded, square-tipped tail. With coloration varying from black, brown, orange, red to yellow, these birds are about the size of a Robin.
Male vs female
Male Red-winged blackbirds are noticeable with shoulder patches that may be either evident, particularly in song display, or mostly concealed by body feathers. These patches are typically bordered yellow, but in central California, these can be entirely red. Females, on the other hand, present very differently. They display streaky brown coloration with a buff eyebrow.
Juvenile
Younger red-winged blackbirds, like the females, appear streaky brown. They resemble sparrows but possess different behavior aids, darker lower belly, and a spikier bill distinguishing them from the common sparrows. With age and seasonal variations, their coloration and physical traits progress and develop into that of respective adult males and females.

Visual differences
Yellow-Headed Blackbirds are slightly larger (8.3-10.2 inches) with predominantly black plumage and striking bright yellow heads in males. They feature white wing patches visible in flight. In contrast, Red-Winged Blackbirds are smaller (7-9.5 inches) and have black plumage with distinctive red shoulder patches bordered by yellow in males. Females are streaky brown with a buff eyebrow. Both species have broad, rounded wings and square-tipped tails, but their color patterns and the presence of wing and shoulder patches differentiate them significantly.
Key differences and behavior
Both Yellow-Headed and Red-Winged Blackbirds share marsh-dwelling habitats but exhibit notable behavioral distinctions. The Yellow-Headed Blackbird nests in reedbeds and tends to push out Red-Winged Blackbirds, displaying aggressive territorial behavior. In contrast, Red-Winged Blackbirds are more famously territorial, even attacking larger intruders. Yellow-Headed Blackbirds, while colonial nesters, only assist the first mate, whereas Red-Winged males may have several mates and use distinct displays to attract them. Both species primarily consume insects and seeds but differ at feeders; Red-Winged Blackbirds frequently visit them, unlike their Yellow-Headed counterparts. Yellow-Headed Blackbirds are less social outside breeding, while Red-Winged Blackbirds form massive communal winter flocks.
