May Tenth
In summer the most common of our Northern wood warblers, yet one of the most difficult to see, on account of its liking for the tops of the tall trees, is the black-throated green warbler. Its song is a cheerful, interrogative, "Will you co-ome, will you co-ome, will you?" (Wright), or "a droning zee, zee, ze-ee, zee." (Chapman and Reed.)
