CF2C7611-001The Common Yellowthroat is a small warbler with olive-yellow upperparts, bright yellow throat and breast, and pale gray belly.  A distinctive field mark is the black mask with a thick white border above on its head.  This warbler also has a loud recognizable song.  They arrive in early May and build large nests close to the ground near swampy thickets, overgrown meadows, and tangles near streams.  This male Yellowthroat was seen last week singing in thickets off of the Shining Sea Bikeway near Oyster Pond.
