The seasonal occurrence of the above species is broken down in the follow- 
ing table, with the year broken up into 24 divisions, representing the first 
and last halves of each month. Effort has been made to equalize the number 
of field trips for each month of the year, but of course this could not always 
be conveniently done.

In the case of the Tufted Titmouse, nearly all of the 181 observations have 
been in the southern and western portions of the Chicago area, with a very 
poor representation from Lake County, Illinois, and from the northeastern 
part of Cook County. This paucity of records from this area, even though 
it has been well studied, is worth further investigation on the part of our 
interested readers.
