Black-headed Grosbeak

                Ah, spring!

This male Black-headed Grosbeak is well dressed for the 2019 find-a-mate match-up season.

He will make a pretty good 'catch', too.

According to Cornell Lab of Ornithology, All About Birds, the Black-headed Grosbeak males
"... share the chick-rearing duties of sitting on the eggs and feeding the young about equally."

This is not typical male nesting behavior, although males generally provide protection and feed the female during incubation.

She likely would be impressed by the male's sweet whistled song, too.

It's solely the female's choice and only she know what will make a good mate.
