512 APPENDIX. 



Nests and Eyys. NESTS, placed on or near the ground, composed of pine leaves, fine roots, and grass. EGGS, four in 

 number, oval in form, ashy-white in color, spotted with brown and lilac. Dimensions from '45 x '60 to 48 x 05. 



HABITS. 



' The Canada Flycatching Warblers are very abundant during some seasons, in Eastern 

 Massachusetts, when migrating, and a few doubtless remain to breed, though the majority 

 go north to nest. This species, like all members of the genus, are expert fly-catchers, and 

 frequent swampy thickets, but when migrating, are more generally distributed. 



MYIODIOCTES MITBATUS. 

 Hooded Warbler. 



Myiodioctes mitratus Aun., Syn.; 1839, 48. 



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

 all around, and upper hreast, black. Patch on forehead, extending around to ear coverts, and under parts, bright yellow. 

 Patch on inner webs of three outer tail feathers, white. Female, similar, but with the crown like the back, and the sides 

 of head are tinged with greenish. 



Observations. Known by the broad bill and black throat. Breeds from New York, west and south; winters south of 

 our limits. DIMENSIONS. Length, 5'25; stretch, 8'flO; wing, 2 - 75; tail, 2'58; bill, "77; tarsus, -38. 



Nests and Eyys. NESTS, placed in bushes, composed of grass, moss, and fibrous roots. EGGS, three or four in num- 

 ber, oval in form, white in color, spotted with reddish-brown. Dimensions from '46 x '62 to '50 x '68. 



HABITS. 



The favorite resort of the Hooded Warblers are the thickets formed by the great laur- 

 el, or rhododendron, and wherever this grows wild, these pretty Warblers are i'ound; and 

 they usually place their nests among the glossy green leaves of their favorite bhrubbery. I 

 have always found the Hooded Warblers very retiring in habit, even giving the loud, clear 

 song while in concealment. 



MYIODIOCTES PUSILLUS. 



Wilson's Black-cap. 

 Myio dioctes pus'Mus Bon. Con.; 185<>, 315. 



SP. Cii, Form, slender. Size, small. Color. Adult mate. Above, yellowish-green, becoming brownish on wing and 

 tail. Forehead, sides of head, and under parts, bright golden-yellow. Square patch on crown, bluish-black. Female, sim- 

 ilar but the black of crown is not as extended. Youny, similar to adult, but there is no black patch on crown. 



Observation*, llecognized by the flattened bill and continuous yellow beneath. Breeds from Canada, northward, win- 

 tering south of our limits. DIMENSIONS. Length, 4'60; stretch, 7'00; wing, 2'25; tail, 2 2fi; bill, "35; tarsus, -70. 



HABITS. 



Wilson's Black-cap resembles the Yellow Warbler somewhat, when among the bush- 

 es, but is much more active and may readily be distinguished upon a nearer view. They 

 are fond of thickets which border streams, and are common during some seasons, in our 

 eastern section, from Pennsylvania, northward, while I found them rather numerous in 

 that state in autumn. Adults of the members of this genus, appear to be as bright in au- 

 tumn as in spring. 



HIKTJNDO LUNIPRONS. 



Cliff Swallow. 



Hirundo lunifrons SAY, Long's Exp. II; 1823, 47. 



SP. GH. Form, robust. Size, medium. COLOR. Adult. Above and spot on throat, steel-blue, streaked on back with 

 ashy. Wings and tail, brown. Forehead, creamy-buff. Hump, pale chestnut. Sides of head and throat, deep chestnut. 

 Beneath, brownish, becoming nearly white centrally. Iris, bill, and feet, brown. Youny. Quite similar but duller. 



Obserralions. Known by the chestnut rump. Breeds throughout our section. Winters south of our limits. DUIE.V- 

 SIGNS. Length, 5'75; stretch, 12-15; wing, 4'30; tail, 2'00; bill, '58; tarsus, -30. 



Nests and Eyys. NESTS, placed under cliffs or eaves of buildings, globular in form, and composed of mud. EGG?, 

 four to six in number, oval in form, white in color, spotted and blotched with reddish-brown and lilac. Dimensions from 

 50 x "75 to '56 x '85. 



HABITS. 



The Eave Sw.illows are among the most common of our Swallows, but are somewhat
