Songs
The Black-headed Grosbeak's whistled song rises and falls like an American Robin's, but it’s longer, sweeter, more varied, and less choppy in its phrases. It's sometimes likened to that of a "drunk" or "operatic" robin. Both males and females sing. The female's song is usually shorter, simpler, and quieter. She sings less frequently than the male, usually from the nest.
Calls
The Black-headed Grosbeak's typical call is a sharp spik uttered frequently to keep contact with mates while foraging. They utter an upslurring wheet upon taking flight. Their distress call is a series of rapidly repeated notes flung out in response to imminent danger to themselves or their chicks, or in violent altercations with other grosbeaks.
Backyard Tips
Attract Black-headed Grosbeaks by setting out sunflower seed feeders, and don't be surprised to find them at nectar feeders set out for orioles. They'll even nest in backyards and gardens where enough cover is available and water is nearby.
Find This Bird
Listen for the Black-headed Grosbeak's rich, lilting song in the treetops and its abrupt spik call as it gleans in dense foliage from spring through summer. It may be easiest to spot at sunflower seed feeders, but you may catch a glimpse of it in almost any diverse habitat, especially those with a few large trees and complex understory.
