HAS. Eastern United States, chiefly in the Mississippi Valley, where breeding abun- 

 dantly in willow swamps, north to at least 40 in Illinois and immediately contiguous 

 States. Straggling northward (blown by storms) to Maine and New Brunswick. Winters 

 in Cuba, Yucatan, and southward to Panama, 



SP. CH. Back olive-green; wings, rump and tail, plain bluish gray, or plumbeous; 

 head and lower parts yellow, the latter white posteriorly; inner webs of tail feathers 

 (except middle pair) white tipped with dusky. Adult male in spring: Entire head and neck,

 tinged or washed with olive-green, but often pure yellow. Bill uniform deep black; iris

 lighter, or less inclining to cadmium, the top of the head always (?) overlaid by a wash

 birds.
