Black-headed Grosbeaks on Gabriola

Lately, a pair of Black-headed Grosbeaks have been visiting our back yard and singing their complex lilting song (sometimes described as like that of a tipsy robin) in the trees behind our house. I love spring. Here are some photos of the male.


These stunning birds spend the winter in Mexico and migrate north during the spring to breed. As far as raising the babies is concerned, grosbeaks have an egalitarian relationship: the male and female share nesting duties. Here's a photo of the female.

Her plumage is much less flambuoyant than the male's. But (unlike most other species) she does sing! You can hear several variation of the Black-headed Grosbeak song at

These birds are one of the few species of bird that eat Monarch butterflies while wintering in Mexico. Most birds cannot tolerate the toxins in the butterfly.
