K Dikov 1952 Barnes atricristatus Feb 20. Palo Duro Canyon, 13 mi. E Canyon, ±3400 ft, Randall Co, Texas CLEAR, COLD, CALM. Ice on stream although water after 8:30 running. I walked along stream W of road inside Park. I whistled but heard no Atrice. I followed their tributary under a bridge to the main stream (100 yds). Cottonwoods scattered along this streamcourse – junipers on flat to E. I heard Atrice singing peel – – – (5 phrases) and located bird in junipers near road. Another Atrice upslope was answering the song but I could not locate it. First moved to cottonwoods on E side of stream and I watched it as it perched on branches conspicuous, then shifted to another cottonwood. Bird sang steadily for 12 minutes although other stopped after this bird moved into cottonwood. This Atrice moved along downstream, singing intermittently. [illegible] I went upstream 1 200 yds after 8:55 but located no Atrice here. I left area after 9:10.
