Bufo brevis
May 24 1.3 mi. N, 0.2 mi. W Centa Carter Richmond, Carter
Carter Co., Calif. - 2:30 P.M. This area not visited
since March 23, 1956. Pond A has dried up to a
point where only 1/5 of original pond area is covered by
water. Maximum depth 15-16" largest pool on west side.
Heavy sedge + cattail growth, latter for 7 feet. Water
slightly muddy. Water temp 1" below surface in water
10" deep (very today) 27.8°C at 3:37 P.M. Air 2"
above water, bulbs shaded 21.9°C. Undisturbed toads select
surface layers of water probably for optimum temps. Little
crogs in bloom. Bufo and Rana toads emerging late this
afternoon from under sedge and grass stems. Largest Bufo toad [illegible] body
length, Bufo smaller <15 mm. Body length. Widespread
numerous
dispersion of a toad over all available water suggests
migration subsequent to my March 23 check. Bufo and
Rana have emerged, are hopping about over muddy areas
adjacent to pond. Bozy sun today, sky 1/4 clouded
light cumulus cumulostratus type, wind strong from S & SW.
Largest metamorphosed toads about 12-13 mm., tail resorbed.
Most of these are at N end of pond A suggesting that
they resulted from eggs I had observed at this end of
pond. One yearling (44 mm.) found in sedge N end.
