BIRDS OF EASTERN MASSACHUSETTS. 99 



throated Warbler. Abundant summer resident; breeds, 

 commonly* in marshy or swampy places. Arrives from 

 May 1st to 13th ; leaves about the first week in October or 

 the latter part of September. 



27. G-eothlypis Philadelphia, BAIRD. Mourning 

 Warbler. Very rare. May 21, 1866, Mr. William Brew- 

 ster shot a male in Cambridge, on the top of a tall tree. 

 Another specimen of the same sex was taken at the Fran- 

 coma Mountains, New Hampshire, on August 3, 1867. " It 

 was in company with four fully fledged young, which it was 

 feeding. The young, being shy, and in a thicket of low 

 bushes, were not procured. The old bird was catching flies 

 after the manner of the Flycatchers." * I have met with 

 this species but once ; that was in May, among low bushes, 

 in a swampy place. 



28. OpororniS agilis, BAIRD. Connecticut Warbler. 

 Very rare, especially during spring. I can record but four 

 instances of its capture, a male, among low bushes, in 

 Newton Centre, on September 16, 1867, by Mr. L. L. 

 Thaxter; I procured another male in September, 1868, 

 also among low bushes, in a swampy place. My specimen 

 was very shy. It was exceedingly fat ; I never met with a 

 bird more so. Mr. H. A. Purdie has also taken specimens 

 twice in September. 



29. Icteria viridis, Box. Yellow-breasted Chat. Ex- 

 ceedingly rare summer visitor. Shot a male in full plu- 

 mage in a swampy thicket in the spring of 1862. This 

 is the only instance recorded of its capture in this 

 locality. 



30. Helminthophaga ruficapilla, BAIRD. Nash- 

 ville Warbler. Common on the migrations. A few breed. 

 Arrives from May 6th to 18th ; departs in September. 

 Frequents the woods everywhere, generally keeping near 

 the tops of the trees or on the higher branches.
