BIRDS OF EASTERN MASSACHUSETTS. 105 
said were taken in eastern Massachusetts, in spring, upon 
apple-trees when in bloom. 
47. Myiodioctes pusillus, Boy. — Black-capped Fly- 
catching Warbler. Not uncommon during the spring mi- 
grations. Have taken it from May 18th to 24th, but have 
never seen it in autumn. It sings well; has more of the 
habits of a Warbler than a Flycatcher. Frequents thickets, 
often by the side of a stream; I have also shot it on the 
tops of high trees. , 
48. Myiodioctes Canadensis, Aup. — Canada Fly- 
catching Warbler, Common during the migrations. I 
have taken it from May 22d to June 4th. It is said to 
breed. Frequents low bushes on the edges of woods. 
The Hooded Flycatching Warbler (M/yiodioctes mitra- 
tus, Aud.) may occur, but 1 have yet to meet with a single 
well-authenticated instance of its capture. 
49. Setophaga ruticilla, Swaiy. — Redstart. Com- 
mon summer resident. Arrives from May 5th to 19th; 
last seen about Septemher 10th. This species loves the 
deep woods, where it builds its nest, generally in the fork 
of a high limb, on some lofty tree. 
HIRUNDINID.4:, — THE Swattows. 
50. Hirundo horreorum, Barton. — Barn Swallow. 
Very abundant summer resident. Arrives the last week in 
April ; departs in early September. Nests in barns. 
51. Petrochelidon lunifrons, Cas. — Cliff Srwallow, 
Eaves Swaltom, Common summer resident. Arrives the 
first week in May; leaves in the latter part of August. 
Breeds under the eaves of barns, generally in associations, 
hundreds sometimes choosing one building; hence it is 
sometimes called the “ Republican,” or “Sociable Swallow.” 
Formerly nested under cliffs. 
52. Tachycineta bicolor, Cas. — White-bellied Swal- 
35*#
