Males look dark black on top with a white wing spot and white belly. But when the sun hits, the feathers on his back turn a dark blue. The female which is olive brown and tan with a faint black eyebrow, looks very different in appearance from the male.
Black-throated Blue Warblers nest in northern Michigan. We see them in the spring and then they’ll pass through mid-Michigan again mid-August to late September.
They build an interesting nest using cobwebs and spit to glue bark together and line it with soft moss, pine needles and animal hair. The nest is usually constructed in a shrub 3ft off the ground in large undisturbed deciduous and mixed-deciduous forests up north.
Listen for their slow, wheezy, rising song of I’m lay-zeeee throughout the day during migration.
