Am I Sexually Dimorphic? You Betcha!So a helpful reader let me in on what "sexually dimorphic" meant when I wondered about it in an earlier post, after reading it in the bird book today. It said the black-throated blue warbler was "one of the most sexually dimorphic of all the wood warblers. "
It's a piece of cake -- it means the boy warblers and the girl warblers look different. In fact, the coloring on the male and female warblers is so different, I knew as soon as I saw the identifying marks and photo that I had a male bird in my hands.
