tracted by heavy timber. It has been found breed-

Pocopson, Birmingham and Highland; the vicinity

took his first set of eggs of this species on Feb. 22, 
1868. Since then he has taken some twenty sets, 
and with the single exception of one set of three, the 
complement consisted of two eggs; the dates ranging 
from Feb. 1 to Mar. 3; all open nests, 20 to 90 
feet up (Orn. and Ool., 1886, 85; Kan. City Sci.,

in hollow trees, and the earliest date for a full set 
was Feb. 15 (Cass., vi, 54).

court house at West Chester, in broad daylight 
(Kas. City Sci., v, 3). Montgomery states that a
