Evening Grosbeak Male (Coccothraustes vespertinus) photos by Larry Jordan
The Evening Grosbeak (Coccothraustes vespertinus) is a striking bird. With his dark head accented by a bright yellow forehead and supercillium, the male really stands out in a crowd. His black wings and tail contrast with his yellow scapulars and flanks, and large white wing patches. Click on photos for full sized images.
The female is more subtle in her plumage but gorgeous in her own right. Being mostly grayish brown on her upper parts, she has a yellow wash on the sides of her neck and a very sporty black and white patterned tail, with black wings that also have contrasting white and gray patches.
As you can see, Evening Grosbeaks visit bird feeders, often during fall and winter irruptions. They may also breed outside their normal breeding range following major winter irruptions1. Range map courtesy of Natureserve.
The birds pictured above graced my yard twice last year. A small flock arrived in mid-March not quite in full breeding plumage.
My guess is that they were pairing up at this time, moving to higher ground where they usually nest. We live in the foothills at an altitude of about 1600 feet, primarily oak savannah and Gray Pine but we do have some Ponderosa Pine on and around our property which Evening Grosbeaks will use for nesting, although in California they prefer White Fir and Jeffery Pine found at higher elevations1.
The grosbeaks were gone for a couple of months and returned at the end of May in full breeding plumage. Note the size of the male Evening Grosbeak relative to the Lesser Goldfinch in the foreground of this photo.
The only difference in non-breeding and breeding plumage of the Evening Grosbeak is the color of their rather large beak which turns a pale, pearly green color during breeding season.
Larry Jordan was introduced to birding after moving to northern California where he was overwhelmed by the local wildlife, forcing him to buy his first field guide just to be able to identify all the species visiting his yard. Building birdhouses and putting up feeders brought the avian fauna even closer and he was hooked. Larry wanted to share his passion for birds and conservation and hatched The Birder's Report in September of 2007. His recent focus is on bringing the Western Burrowing Owl back to life in California where he also monitors several bluebird trails. He is a BirdLife Species Champion and contributes to several other conservation efforts, being the webmaster for Wintu Audubon Society and the habitat manager for the Burrowing Owl Conservation Network. He is now co-founder of a movement to create a new revenue stream for our National Wildlife Refuges with a Wildlife Conservation Stamp.
