40. Dendroeca Pennsylvania (Linne) Baird. Chestnut-sided Warbler. 

 A summer resident ; breeds. Very abundant during migrations. 



Arrives early in May (7), the greater number passing north before 

 the first of June. 



41. Dendrceca maculosa (Gmelin) Baird. Black-and-yellow Warbler. 



A common spring and auiumn migrant. Arrives about May 12th, 

 remaining till June 1st. Have taken it in the fall, from the middle 

 of September to October 1st, and it probably remains still later.* 



42. Dendroeca tigrina (Gmelin) Baird. Cape May Warbler. 



A rather rare migrant, though a few are taken every season. Have 

 known of its occurrence from May 10th, (Osborne) to the 25th. Mr. 

 Shores writes me that it is generally rare about Suffield, Conn., but 

 that it was not uncommon there in the spring of 1876. 



43. Dendroeca discolor (Vieillot) Baird. Prairie Warbler. 



A summer resident ; not common about New Haven. Breeds spar- 

 ingly. Mr. Dayan has taken it on May 13th and Sept. 15th. Mr. W. 

 W. Coe tells me that it breeds near Portland, Conn., but is rather rare. 

 I shot one near New Haven, May 14th, 1877. I am informed by Mr. 

 E. I. Shores, of Suffield, that it is not rare about Enfield, Conn. Mr. 

 J. N. Clark tells me that it breeds plentifully about Saybrook, Conn. 



44. Dendroeca dominica (Linne) Baird. Yellow-throated Warbler. 



A rare accidental visitor from the south Dr. Daniel Crary, of Hart- 

 ford, Conn., writes me that during fifteen years of bird collecting in 

 that vicinity (in the Connecticut Valley) he has secured several speci- 

 mens of this rare species. Dr. E. L. R. Thompson also assures me that 

 he has seen it about New Haven. Coues, in his " List of the Birds 

 of New England," states, and very properly too, that " there is no 

 good evidence," that this species " ever straggles as far north as 

 New England,"f but, for some unaccountable reason, in his " Birds 

 of the Northwest" (p. 66) disregards his former correct statement 

 and says that the bird occurs "north to Connecticut (Linsley)." A 

 glance at Linsley's catalogue shows that he did not know of its 

 occurrence in this State.
