known. Like so many of these beautiful Warblers, persons, gener- 

 ally, are unfamiliar with its great beauty and usefulness. 



Xest I have found a number of the nests of this Warbler. They 

 are placed, as a usual thing, rather low in the crotch of a bush of 

 some kind.

685. Wilson's Warbler (Wilsonia pusilla). A pair of adults. 

 Sometimes called the Black-capped Fly-catching Warbler. 



Geog. Dist. Eastern United States, north to Hudson Bay, Labra- 

 dor, and Alaska. 



W. Va. Dist. Known in this state only as a rare migrant. 



Xest On the ground. Breeds north of the United States, a few 

 nesting in northern Maine. 



Food I have no food record of this species. Often flies inlo 

 the air and catches insects on the wing. 



686. Canadian Warbler (Wilsonia canadensis). Male and fe- 

 male. This species may be recognized always by the necklace of 

 black spots across the breast. 



Geog. Dist. Eastern North America, north to Newfoundland and 

 Athabasca.

 In the mountain section it remains through the summer to breed.

 in this state. 



Food Insects. 



687. American Redstart (Setophaga ruticilla). Male and fe- 

 male. Note the decided difference in the colors. This pretty bird 

 is to be found along streams in the deep woods. 



Geog. Dist. Eastern North America, far to the north. 



W. Va. Dist. Abundant in most parts of the state. Not found 

 in the mountains. 



Nest In the crotch of a sapling. 



Food "Apparently there are few forest insects that do not. iit 

 some forms, fall a prey to the Redstart. It takes its prey from 

 trunk, limbs, leaves, and from the air. Destroys some useful para- 

 sitic Hymenoptera. ' '
