Harbuckson 1950 Empidonax (traillii?) Sept. 9 Stubby Spring, 4500 ft., Riverside Co., Calif. While seated near the large tanks at the spring, I twice saw Traill (?) Flycatchers (different individuals) bath in the tanks. The circumstances are sufficiently new to my experience to warrant mention here. In each case the birds flow from perches or the bush overhanging one side of the tank to the center of the open water, landing with a splash and taking off again almost immediately. Returning to the perch, the ruffling and fluttering of a "typical" bath occurred, followed by industrious preening, then the birds returned for another wetting. One bird "bathed" four times, one twice. The water is about four feet deep in the tank. Although there seem to be a few spots where small birds might stand and bathe (niches in the rim of the tanks), I saw no birds using them. About 20 feet up from the tank is the seep, where there seem to be good bathing spots. The hazards associated with birds such as these flycatchers bathing in deep water might be indicated by one
