Bird Migrations for Columbus.

however being merel}' 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 18th to the 22d 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 placed after the species. Species not followed by names have 
been recorded by several 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.
