510 APPENDIX. 



specimens have been taken in several localities in the New England and Middle Slates. 

 Nothing special is known of the habits of this species. The specimen figured in plate XXII 

 was obtained for me by Mr. Purdie, and w;is killed at Saybrook, Connecticut, by Mr. J. 

 N. Clark, on the thirtieth of May, 1879. 



HELMINTHOPHAGA BACHMANI. 



Bachman's Warbler. 



Helminthophaya Bachmani CAH., Jour. Orn., Ill; 1855, 475. 



Si'. Cn. Form, slender. Size, small. COLOR. Adull. Above, and on sides of head and neck, yellowish-green, tinged 

 with ashy on crown. Patch on forehead, and beneath, deep yellow. Band across crown, throat, and upper breast, black. 

 Patch on inner webs of two outer tail feathers, white. 



Observations. Known by the black throat and band on top of head. Kare on coast of South Carolina DIMENSIONS. 

 Length, 4'50; stretch, 6-25; wing, 2'35; tail, 2'05; bill, "40; tarsus, -65. 



HABITS. 



As far as I can ascertain,- Audubon is the only ornithologist who records the actual 

 capture of this very rare Warbler, in the United States, and his specimens were obtained 

 in South Carolina, in July, 1833, near Charleston; therefore it is rather doubtful whether 

 this bird should now be considered a bird of our section. Bachmau's Warbler is said to 

 occur in Cuba. 



HELMINTHOPHAGA PEREGRINA. 



Tennessee Warbler. 



Helminthuphaya pereyrina CAB., Mus. Hein.; 1851, 20. 



SP. Cn. Form, slender. Size, small. COLOR. Adult male. Top and sides of head and neck, bluish-ash; remainder 

 of upper parts, yellowish-green. Beneath, white slightly tinged witn greenish-yellow. Inner webs of outer tail feathers, 

 edged with white. Iris, bill, and feet, brown. Female, more yellow beneath and the ash of head is obscured by greenish. 

 In autumn, and Young. Similar to summer female but much more yellow beneath, and the ash of head is quite obscured 

 with greenish. There is a short, dusky line bnck of eye, and the wing feathers are tipped with white. 



Observations. Known by the absence of any chestnut or black markings. Distributed in summer from Northern 

 Maine, northward; winters south of our limits. DIMENSIONS. Length, 4'75; stretch, 8'35; wing, 2'55; tail, T65; bill, '90; 

 tarsus, '40. 



HABITS. 



The plainly colored, little Tennessee Warbler was quite abundant in Northcn Maine, 

 some years ago, but has always been very rare in Massachusetts. It is, however, very 

 common in Pennsylvania during autumn, but is not met with so frequently in spring, in 

 this section. For other habits of this and allied species, see remarks on page 64. 



GEOTHLYPIS PHILADELPHIA. 



Mourning Warbler. 



Geothlypis Philadelphia BD., Birds N. A. ; 1858, 243. 



SP. Cn. Form, robust. Size, medium. COLOR. Adult male. Above, and on sides, yellowish-green. Bright yel- 

 low beneath, with head and neck all aronnd and upper breast, black, overwashed with ashy, female, similar but with 

 the head tinged with greenish. Young. Similar to female, but overwaslied with greenish on ashy. 



Observations. Known by the dark head and neck. Occurs in summer from Maine, northward; wintering south of 

 our limits. DIMENSIONS. Length, 5'50; stretch, 7'80; wing, 2'45; tail, T90; bill, "75; tarsus, -45. 



HABITS. 



The Mourning Warbler is quite rare, both in Pennsylvania and Massachusetts, in 

 spring and fall, but is not uncommon in Maine, frequenting thorny thickets, and behaving 

 much like the Maryland Yellow-throat. The song is, however, much finer than that of 

 the latter named species, being a long, clear warble, and is given early in the morning, 

 while the bird is perched in some slightly elevated situation. 



OPORORN1S AG1LIS. 

 Connecticut Warbler. 

 Opornrnis ayi/is BD., Birds N. A. ; 1858. 246. 

 SP. Oil. Form, slender. Size, medium. COLOR. Adult male. . Above and on sides of neck and sides, dark yellow
