Christmas Gensus: —91950 
REPORTS OF CHRISTMAS censuses have been published in the Bulletin since 
1932, and we are happy to continue the practice. As usual, the reports are 
largely from the Chicago region. We hope to hear from larger portions 
of the state in years to come. 
It would help in the work of preparing copy for the printers if writers 
would examine the form used in the Bulletin when preparing manuscript 
for these reports. This includes such points as arrangement in a paragraph, 
punctuation, capitalization, and order of names and numbers of individuals 
of a species observed. The manuscript should be typed double space. 
When so many individuals of a species are seen that it is not feasible 
to count them, we suggest that a plus sign be used, e.g. 1507+, the number 
being of course a conservative estimate. It should be interesting to read 
reports of other years and note changes in the bird population of Illinois 
and possibly determine the factors responsible for such changes.
