the flight as swift, with frequent abrupt turns, and states that these 
bats do not appear until the light becomes very dim. 
A female hoary bat secured at Merced Lake, Mariposa County, was 
shot at 7:12 p.m. on the cloudy evening of August 21, 1915, as it 
flew among the lodgepole pines at a height of about thirty feet above 
the ground. 
Merriam (1884, pp. 176-181) gives an interesting account of this 
bat as occurring in the Adirondack region of New York state. There 
the hoary bat was the latest of the observed species to appear in the 
evening. Merriam states that this bat may be recognized in the dark 
by its great size, long and pointed wings, and the swiftness and 
irregularity of its flight. 
Seton (1909, p. 1169) states that the hoary bat is the only known 
species which is never gregarious. As occurring in California it is 
certainly a notably solitary species. The only evidence to the con- 
trary is afforded by the female hoary bat secured at Fresno, April 3, 
1915, which was found hanging in a mulberry tree is company with 
“‘many’’ red bats. 
Seton (1909, p. 1196) states that four is the usual number of 
young at birth. Banta (in McAtee, 1907, p. 8) states that there is 
in the museum at the University of Indiana a female hoary bat which 
when captured was found to have two young clinging to it.
