Chestnut-Sided Warbler — Setophaga pensylvanica
As the name implies, this warbler has a chestnut colored streak on its side. It also has a yellow area on top of the head and a white breast. The female is similar, but with less coloring. The Chestnut-sided Warbler favors second growth deciduous woods and roadside thickets. It nests in the northern United States and Canada, as well as, in the mountains of Virginia. Its song is referred to as "pleased, pleased, pleased to meet you".
