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. Geothlypis 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- 
conia 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, Bon. — Yetlow-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. — iVa^A- 
mlle 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.
