Remsen, J.V. 1975 Chestnut-collared Longspur Calcaricus ornatus Sep. 6 Briggsdale area, Weld Co., Colo: 50 (NBP) in Murphy's pasture. Call note is much more liquid than McCown's or Lapland: "chew-tent" or "chew-tetele" and or white shoulder much softer. At least 10 individuals were seen with white wing-bars and buffy underparts which could easily have been mistaken for Smith's longspur, but they gave the same call as obvious Chestnut-collareds and were smaller than McCown's; also, tail pattern fit Chestnut-collared. Flocks of 4-8 birds. Tail pattern cannot be properly observed unless the bird is spreading the tail, as when landing; in flight, it appears as if only the outer edge of the tail is white (as it should be in Smith's). Sep. 12 Briggsdale: 75 (NBP) - again, several seen with large white Nov-23 wing patches (either shoulder area or 2 white wing-bars). Occasionally gives a soft twitter
