June12 La Laguna,6200 ft, Sierra de la Laguna, Baja California
the night before last (#342), both in the same
location and at about 7:30 P.M. This species
feeds first in and over oak and medium
forest at its margin of the flat, venturing
to feed below tree level on the flat at late
dusk and dark. Are quite common here.
June17 Pozo Grande, 25°46'N, 112°02'W, Baja California
Five shot (3 8,2 Q)(#371-375incl.) this evening
between 7:30 and dark. The females contained no
embryos. The first bat was seen at 7:30 and it
was this species. All were feeding about and
up and down the wash containing the large pool.
They fed at a height of about 6 feet to 20 feet,
fling into the wind and making the characteristic
"chipping" sound as they moved slowly above the
ground, shooting at them seems to bother them
but little, the usual occurrence, if they were not
hit, is for them to dive and catch the shotgun
wad in mid-air. Several times it has happened
that after shooting at and missing one of this
species it has dove down and flown within
a few inches of the smoking barrel, one even
hitting it with its wing last night. If not
killed when hit by the shot this species will
lie quietly on the ground with wings folded close
to its body until touched or picked up whereupon
it assumes a menacing attitude with wings spread
