Journal Mar 31. Aransas River, 5 1/2 mi. ENE Skidmore, Bee Co., Texas See acct for Paris. At the mouth of the 1st tributary on the N side of the river below the bridge, I noted a very small gray frog leap into the water. Others did likewise and I was unable to capture any for a while. They tended to jump in and swim back to the bank at a different point, diving in again if they saw me more. Others, however remained in the muddy water for some time before climbing out on the bank. I was able to capture two (#520, 521) About 4:45, as I was watching these frogs, I heard a grating call ck-ck-ck, a sequence of notes uttered rapidly from a point a few yards upstream. The call was given from other points then, always from the margin of the stream it seemed to [illegible] These calls continued intermittently. At dusk I heard a chorus of similar sounds far along the river, a chorus I was not aware of on previous evenings. I collected a tadpole (#519) from beneath a leaf floating at the water's edge. Hind legs were not visible yet; color did not seem to change when it was preserved. Occurrence of a tadpole is a little surprising although there were a few pools extant in this area of the river before the rain. The river is not running yet although the standing pools form an almost continuous body of water. Residents stated that this was the first rain in about a year (the one of March 25-26) I departed at 5:10 pm. Toward sunset the clouds cleared away completely but the wind velocity did not change. I spent some time watching Lark Sparrows, then stationed myself to shoot bats at 7:10. No flight took place
