Mar 29. Spring Creek, 61/2 mi ENE Skidmore, Bee Co., Texas I had first picked it up - seemed to be alone. (juniper and yellow-throated warbler and black-and-white warbler were following along with it.) Bird sang little after 10:00 - gave call vet vet which could be transcribed enke enke when heard at a distance. The habitat here is of scattered trees, post oaks (leaves shed) 15-20 ft high and a few willow mesquites and several brush species growing to 8 ft. 10:14 enke enke farther E, then peta - - - WIND STRONGER FROM NW. Bird still singing as I walked SW. The "cattleguard" point of reference actually was an oblique fence corner with white rails on either face". The bird was to the East generally of this corner & hence NE of the other terminal. These two singing birds seemed to be unmated - I thought I'd check on them again in the early morning and collect them then. Two other males seemed to be unmated - one along the river E of the bridge, the other on the extreme E end of the Driscoll ranch - care must be taken to determine if there is an unbalanced sex ratio. Texmore singing along creek near road in large live oaks at 10:30 - I followed creek E, walking for about half a mile (until 11:05) then returning via the same route. I heard no thrice in that area but those where I had hunted earlier were silent as I took photographs and collected plants, 11:35-12:05. SUNNY, COOL, WIND 12-14 mph, blowing loose leaves in its path.
