dent of many of the elevated parts of 

 Massachusetts, although less numerous 

 than either the Magnolia or Black-throated 

 Blue Warblers, this Webster breeding of 

 the bird appears to be the first recorded 

 case of the actual nesting of the species in 

 the state. — John A. Farley, Boston, Mass. 



Bird Migration in Ontario 



One of the first acts of the Hamilton 

 Bird Protection Society, which was 

 recently organized at Hamilton, Ontario, 

 Canada, and which is now a member of 

 the National Association of Audubon 

 Societies, was to compile a list of the dates 

 upon which the migratory birds were first 

 observed in its district this year. Members 

 of the society handed in records of their 

 observations, and a list of seventy species 

 was published in the local newspapers. 

 The society intends to compile a similar 

 list each year, and hopes that future lists 

 may be more complete. This list, which 

 follows, may interest some of the readers 

 of Bird-Lore:

THE SEASON 



XV. June 15 to August 15, 1919 



Boston Region. — Except for several 

 sudden changes in temperature, the 

 weather the past summer has been normal, 

 without unduly protracted periods of 

 heat and high humidity, and with a fair 

 amount of rainfall furnished by gentle 

 summer storms in place of the violent 

 and often destructive thunder showers. 



The birds about the town centers show 

 a marked decrease in number. This change 

 is due, doubtless, as Dr. Allen suggests, 

 to the spraying of the shade-trees which 

 has been responsible also for the complete 

 disappearance from our gardens of the 



tree-cricket {Oecanthus niveus). Some 

 species, notably the three Vireos — the 

 Warbling, the Yellow-throated and the 

 Red-eyed — the Wood Pewee, and the 

 Yellow Warbler, compared to their 

 abundance ten or fifteen years ago, are 

 at the present time rare. The Warbling 

 Vireo is sadly missed, for, with its practical 

 disappearance from the elms bordering 

 Lexington Common and the main streets 

 of the town, very few individuals are left 

 in this vicinity. Rose-breasted Grosbeaks 

 and Baltimore Orioles seemingly have 

 suffered little.
