Yellow-hooded Blackbird Identification Guide

Key Field Marks

• Size and shape: A small to medium icterid, roughly 7-8 inches long, slim-bodied with a fairly straight, pointed bill typical of blackbirds.
• Adult male: Glossy black body with a bright yellow hood covering the head, throat, and upper breast, creating a sharply demarcated two-tone appearance.
• Adult female: Much duller, mostly grayish-brown to olive-brown with variable yellowish wash on the throat and face, lacking the male's crisp, extensive yellow hood.
• Behavior: Forages low in marsh vegetation and reedbeds, often perching conspicuously on reed stems, and breeds in loose colonies in wetland habitat.

Similar Species

• Male Yellow-headed Blackbird (a different, more northern species) is larger and shows a white wing patch, which Yellow-hooded Blackbird lacks; their ranges do not overlap.
• Other South American marsh blackbirds such as Red-breasted Blackbird or Yellow-rumped Cacique differ substantially in the extent and location of yellow or red plumage, making the male Yellow-hooded Blackbird's clean yellow head-to-breast hood distinctive within its range.

Habitat, Range & Season

• Found in freshwater marshes, flooded grasslands, and wetland edges with reeds, cattails, or tall grasses across northern and central South America, including Venezuela, Colombia, the Guianas, and the Amazon basin.
• Non-migratory resident throughout its range, though local movements may occur in response to seasonal flooding.

Voice

• Gives simple, somewhat harsh chattering and buzzy notes typical of marsh-dwelling icterids, along with a thin whistled song used in territorial and courtship display, usually delivered from an exposed reed perch.
