Remsen, J.V. 1975 Pine Warbler Dendroica pinus Sep. 12 Briggsdale, Weld Co., Colorado: I seen closely in Crow Valley Park on three separate occasions as it foraged slowly and deliberately around tree trunks. It was not until the third observation that both John Cooper and myself both saw the back well enough to see that it was definitely uniform - no stripes. There was an eye-stripe which actually formed an indistinct eye-ring. The upperparts were uniform grayish-green. There were two very broad, white wingbars. Underparts were whitish with a smudge of yellow on the center of the breast, a trace on the sides, and a hint on the vent; there wee some small faint specks of darker color on the sides of the breast. We were very impressed with how slowly the bird moved, very un-warbly like, deliberately making its way along branches, hopping on top of them and on twigs adjacent to the branch under search. Interestingly, it was always associating with a White-breasted Nuthatch. Silent,
