Here are some key facts about the habitat and distribution of black-headed grosbeaks:

Black-headed grosbeaks are voracious fruit eaters, enjoying poison oak berries and other fruits like cherries, crabapples, elderberries, and raspberries.

Their strong beaks give them an advantage when it comes to cracking open tough shells, including snail shells and the shells of seeds.

Black-headed grosbeaks will eat insects like beetles, grasshoppers, and butterflies, including the toxic monarch butterfly, which they can eat safely by waiting a few days between snacking sessions.

These birds are also known to eat seeds, including black oil sunflower seed, which is a great option for attracting them to your yard.

In the summer, black-headed grosbeaks will eat a wide variety of insects, including caterpillars, wasps, bees, flies, moths, and spiders.

The Black-headed Grosbeak's song is a beautiful thing. It's been described as similar to an American Robin's, but at a faster pace.

Both males and females sing, which is unusual for songbirds. The male's song is primarily used to defend a territory or attract a female.

The female's song is often a shortened version of the male's, but sometimes she'll sing a full, male-like song. This might be her way of getting her mate's attention.

Their song has a flute-like quality, described as a constantly changing series of notes, or a warble. It's a sound that's hard to forget once you've heard it.

The Black-headed Grosbeak's call is a crisp pik, sharp eek, or tick sound. You can listen to recordings of their songs and calls online to get a better sense of their unique vocalizations.

Predation is a major concern for black-headed grosbeaks, with eggs and nestlings being taken by a variety of predators, including western scrub-jays, magpies, snakes, and rock squirrels.
