Cogswell 1949 Journal 36 May 7. San Joaquin Experimental Range, alt. 1000', SSW of O'neals Makeria Co., Calif. From my sleeping bag this A.M. at 0400 - violet green swallows calling overhead, stars dimming out slightly. 0430 - acorn woodpecker called & flew to another tree. 0500 - most birds in voice; Calif. Quail had just started 0540 - sunrise. Between 0525 and 0600 I covered the area just E. of the headquarters buildings. From 0800 to about 0915 we (Ecology class) were afield near the buildings but with instruction in range management going on, bird & mammal observation was limited. From then until noon we visited (by car) several spots To the S & SW of headquarters including cattle & rodent exclosures & the unused rodent enclosures. From 1330 to 1600 we walked away from headquarters to the NE through the "natural area" (improved since 1934) and returned along the creek just W. of it. I kept noting birds as occasion arose, but found no significant differences in habitat other than in the "yard" around headquarters.
