of April there was a small flight of Yellow Palm Warblers and 

 Pine Warblers, with a few Myrtle Warblers. Both species of 

 kinglets, Winter Wrens and House Wrens came in good num- 

 bers. A large migration of Goldfinches occurred from the 12th 

 to the 18th. There were many early records of warblers, 

 thrushes. Catbirds and a few of Indigo Buntings and Baltimore 

 Orioles. Twenty Bohemian Waxwings were reported in north- 

 ern Vermont on the 17th. During the month many albino 

 Robins were recorded from widely scattered localities. A Blue- 

 gray Gnatcatcher was seen in Massachusetts and another in 

 Ontario, Canada. Two Kingbirds were reported in Massa- 

 chusetts during the last days of the month. Birds, however, 

 with the exception of stragglers, were not much earlier than 

 usual on May 1. The early flight which came on the warm 

 days of March was followed by cold weather in the South, 

 with frost and snow in some localities in the Middle States, 

 and some April weather in northern New England was like 

 that of an ordinary March, 



May, 1921. 



Ice and snow still remained on May 1 in the Maine woods, 

 and a scarcity of migratory birds was noted throughout the 

 greater part of New England. In Massachusetts the foliage 

 had advanced to the stage when the May warbler flights usually 

 appear, but most of the May birds had not arrived.

 gration which had been held out by March and April was not 

 realized. Following the premature advent of spring in March 

 and the succeeding warm weather of early April there were 

 twenty-seven days of cool or cold weather, with wind varying 

 mostly from north to east. Vast quantities of ice were drift- 

 ing down into the north Atlantic, and this influence was felt 

 in the east wind. Storms, mists and local frosts prevailed from 

 time to time over most of the New England region. The period 

 was broken only now and then by one or two days of warm 

 southerly or southwesterly winds. Vegetation, which had ad- 

 vanced far beyond its usual April development, was checked, 

 and although many of the earlier flowers had bloomed much
