brook. Their nests are on the ground in clumps of weeds or 

 at the bases of bushes; composed of dead leaves with the 

 point down, deeply cupped and lined with shreds of bark and 

 sometimes hair. I have always found the male rather shy, 

 except when engrossed in singing, at which times he usually 

 perches rather high up in trees in a commanding position. 



These two species are of unusual interest because of the 

 frequency of hybrids between them. There are two forms 

 of these hybrids. One known as Lawrence's Warbler is like 

 the Blue-winged in plumage but has the black throat and 

 patch on the head like the Golden-wing. This form has been 

 taken only in Connecticut, eastern New York, and New Jer- 

 sey. The more common form, known as Brewster's Warbler, 

 has the plumage like the Golden-wing except that the black 

 on the head is like that of the Blue-wing. Besides the pre- 

 vious states, this species has been found in Michigan and 

 Massachusetts and has been taken during migrations in 

 Louisiana.
