342 THE BIRDS 
FAMILY PARID/E.—TITMICE. 
GENUS BAOLOPHUS. 
[731]. Beolophus bicolor (Linneus). Tufted 
Titmouse. 
Raner.—Carolinian and Austroriparian zones of eastern 
United States from Nebraska, Iowa, LIlinois, Indiana, 
Ohio, Pennsylvania, and New Jersey south to central 
Texas, the Gulf Coast, and Florida; casual in southern 
parts of Wisconsin, Michigan, New York, and Connecticut.

an opening to the natural cavity in a live tree, preferably 
an oak, poplar or black-gum. During eighteen years 
of collecting, in which time numerous families of young 
of different ages were found, not a set of fresh eggs were 
found until the season of 1909. Even then it was a second

late springs seem to have no effect on their breeding time, 
and, from finding young just hatched, I conclude their 
regular time is from the first to fifteenth of April. Four 
and five eggs seem to be a complete set in this locality. 
The nest is composed of leaves and bark fiber, with a 
lining of rabbit fur. The height of cavities varies from
