Chestnut-sided, Yellow, Nashville, Black-throated Green War- 

 blers, and Redstart. Many female Yellowthroats, Redstarts, Wil- 

 son's, and Chestnut-sided Warblers were noticed this morning, 

 these being all the species present in which the female can be 

 readily distinguished from the male. Eight Warbler songs were 

 heard and recognized, among the most persistent of these being 

 the notes of the Magnolia and Chestnut-sided Warblers. The 

 most unusual circumstance of this morning's observation was a 

 flock of surely twenty-five Olive-backed Thrushes, which were 

 abundant for a quarter of a mile in the bushes along the roadsides. 

 As I followed them they fled liefore me, taking refuge in trees and 

 scattering through a hilly pasture. With them was a single Wil- 

 son's Thrush, quite conspicuous on account of his larger size and 

 reddish-brown coloring. Baltimore Orioles were seen feeding 

 busily in cherry trees covered with blossoms, apparently searching 

 for small worms and caterpillars. On the shore of a swampy pond 

 a Spotted vSandpiper was lingering, intent on securing something 

 to eat. This Sandpiper has been arriving for several days, going 

 to inland lakes and streams as well as to the i.slands along the 

 coast. While I was watching the Sandpiper a Loon flew over, 

 travelling northward at a great rate of speed. Chimney Swifts 

 were common this morning, the first flocks having been reported 

 to me two days ago. The Black-billed Cuckoo was this morning 

 seen and heard for the first time. I have noticed for several days 

 that nests of caterpillars were getting to be thick in the woods, 

 and as these caterpillars are the favorite food of the Cuckoo, it is 

 quite likely that many of these birds will decide to stay in this 

 locality to nest. The Nighthawk was reported this morning for 

 the first time, but in a few days there will be no lack of this bird 

 in the city limits, or suburbs. The Chewink appears to be more 

 plentiful this year than for some seasons past, as at least a dozen 

 pairs of these birds have been reported to me during the past 

 week.

 morning a great variety of early blossoms was noted, the Rhodora
