BIRDS OF EASTERN MASSACHUSETTS. 105 



said were taken in eastern Massachusetts, in spring, upon, 

 apple-trees wjien in bloom. 



47. Myiodioctes pusillus, BON. 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, AUD. 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 (Myiodioctes mitra- 

 tuSj Aud.) may occur, but I have yet to meet with a single 

 well-authenticated instance of its capture. 



49. Setophaga ruticilla, SWAIN. Redstart. Com- 

 mon summer resident. Arrives from May 5th to 19th; 

 last seen about September 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^E, THE SWALLOWS. 



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, CAB. Cliff Swallow, 

 Eaves Swallow. 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. 



62. Tachycineta bicolor, CAB. White-bellied Swal-
