OF THE 
WISCONSIN NATURAL HISTORY SOCIETY 
Vol. 13 MARCH, 1915 No. 1 
PROCEEDINGS 
Milwaukee, Wis., January 29, 1914. 
Regular meeting of the society. 
President Barth in the chair. Forty-two persons present. Minutes 
of last meeting read and approved. The name of Miss Rosa J. Katz, 512 
Park Place, was presented for active membership and was referred to the 
board of directors for action. 
The lecture for the evening was delivered by Prof. R. M. Strong, of the 
University of Chicago; the subject being “Home Life of Some Native 
Birds.” Professor Strong gave observations on the gull and tern colonies 
that were observed during a trip to Door County and neighboring islands, 
the special purpose of the trip being to study the birds during the nesting 
season. Found gulls on almost all the unoccupied islands of the Door 
County peninsula. 
The gulls do not get their adult plumage until four or five years of age. 
Have several well marked cries, such as the alarm cry, the joy call or chal- 
lenge call, the mewing call; and a few other minor calls. Gulls are rather 
sensitive to extremes of heat and cold. During a storm, they will face 
the wind. A number of variations in individuals, especially as regards 
nesting habits, were noted by the speaker. A few individuals were ob- 
served to nest in trees. A question if this reaction is due to an inherited 
or acquired character. 
The lecture was illustrated by many colored slides. 
At the conclusion of the lecture, Professor Strong was given a vote of 
thanks by the society. 
The meeting then adjourned.
