Adult male Northern Parulas are bluish gray overall with a yellow-green patch on the back and 2 white wingbars. A chestnut band separates the male's bright yellow throat and chest.
Males and females have distinctive white eye crescents. Immature birds are paler than adults and lack the chestnut breast band.
In the southern part of their range Northern Parulas are more common in deciduous forests, but in the northern part they also use evergreen forests. But no matter what part of their range, the key to their presence is moss; Spanish moss in the South and beard moss farther north.
On the wintering grounds, they forage in fields, pastures, plantations, scrub, and forests. Cornell All About Birds
