Grosbeak

Rosebreasted Grosbeak Pheucticus ludovicianus pair are nesting somewhere nearby in the wild wild woods.  The female is dressed in brown-gray camouflage pattern so she can hide her eggs among the trees; the male sports a rose front to contrast with his black and white tuxedo. Both come to the feeder tray for seed.  But they won't let me know where their nest is!
