A 7-year-old ranch boy, Charles Collins, found “a funny white bird” in a small marshy pond near his home on Lower Piney Creek about 40 km SSE of Sheridan, Wyoming, on 12 September 1976. His father, Bruce Collins, identified it as a White Ibis (Eudocimus albus). Marian Collins (not a relative) and I arrived at the pond at about 0730 on 13 September. The pond, situated in a pasture, was not more than 8 m across and had cattail (Typha) growth and two tree stumps standing in water near its center. The rest of the pasture was rather level and dry with short grass clipped off by the cattle present. The entire valley is made up of such pastures, some plowed and planted fields, some native grasses and sagebrush (Artemisia), cottonwoods (Populus) and willows (Salix) along the stream plus large brushy areas. Low hills rise on either side. Several marshy ponds are in the area—two quite extensive. Piney Creek flows generally from southwest to northeast through the valley.
