Slough Cr, 6300 ft, Yellowstone Park, Wyo. Sept 1 1967 The jacksnipe taken was a young of year flushed from the dense meadow grasses 30 inches high. No bare ground where it came up from. Sept 2 1967 Weather has warmed up again so nights are probably in the 40's. Very little moisture cold night. Visited 2 lakes W of camp hoping to find where the flocks of black birds come from. Found the black birds & then proceeded to muff my chances at them. This was a large flock feeding in the sage brush & grassy hills around the lakes. There were at least 500 birds and they were a mixture of Red-wing- Yellowhead & Brewer. Still having trouble getting shots at the sparrows that pop up out of the grass. Worked around some Doug Firs on low hills bordering the pot hole lakes and saw Wt. Bluebird, few Crossbills, Red-breasted Nut-hatch, Flicker & Wt. Chickadee. Now can find no sign of a flycatcher of any kind. Just 3 or 4 ducks on lakes & in such poor plumage I couldn't identify.
