Bird Migrations for Columbus.

however being merely negative and possibly due to other causes 

 can hardly be cited as strong proof. Attempts to correlate the 

 wave of migration, extending through the latter part of April 

 with the wind direction, can not be called successful except in 

 one instance, that of 1902. In this year the records show a 

 period of cold weather (Temp. 30 to 45 deg.) and prevailing 

 northerly winds extending from the beginning of the second week 

 in April to the middle of the third, with scarcely any records 

 of migration. During the time from the i8th to the 2 2d of the 

 month however, the wind direction shifted to the south and 

 south-west, and the temperature rose to 60 deg. The records of 

 the Ornithological Club for that period contain many records of 

 migrating species, most of them for the 22d and 23d, with the 

 statement that they are about a week early. This is the only good 

 instance of positive evidence in the records, it seeming impossible 

 to establish any clear connection in other instances. In the 

 appended list the date is given, being the earliest record of its 

 appearance by members of the Club and the name of the observer 

 is i^laced after the species. Species not followed b}- names have 

 been recorded b}- se\-eral members for the same time. The records 

 for the Robin, Bluebird and Meadow-lark are not given, as some 

 of these species winter here and of course it is impossible to dis- 

 tinguish the arrivals from the South from those wintering here.
