The following day was nearly cloudless; wind moderate, westerly; temperature, 37.5° to 66°--high enough to bring out the black flies (but extremely few mosquitoes) after several days of virtual freedom from these scourges. Between 11:30 a.m. and 3 p.m. at least 500 Caribou, coming from the east, must have passed the mouth of Little River, some swimming across at that point (figs. 9, 12), and others proceeding various distances upstream before undertaking the passage. A few of the larger bands numbered approximately 30, 40, and 75 individuals. Some consisted largely of does and fawns, some of big bucks. One of the larger bands approached the river on the run, plunged in recklessly, and landed on the western shore some 30 feet directly in front of my battery of cameras. Most of the animals on this and similar occasions were remarkably indifferent to me as I operated the cameras in full view of them. Some among them would approach within a rod or less and stare me in the face without alarm (figs. 11, 14). August 29 was a cloudy, nearly calm day, with temperatures ranging from 49.5° to 73°--conditions more propitious for black flies than for their victims. There was comparatively little local movement among the Caribou--in the morning two or three swimming across the bay and a band of 20 (6 old bucks, the rest does and fawns) swimming south across the mouth of Windy River; in mid-afternoon a band of 10 running along the ridge on the eastern side of Little River; and about 100 reported during the day in the vicinity of Windy Bay by Fred Schweder, Jr. The “big movement” had passed its peak. The next day was largely sunny, with a light easterly or southeasterly wind and temperatures of 50° to 68°. There were comparatively few black flies and fewer mosquitoes. During a five-hour vigil near the mouth of Little River I noticed only about 50 Caribou, most of them passing westward by ones, twos, and intermediate numbers up to 17 (does and fawns) in a band. Mike Schweder reported a total of about 200 animals seen within a few miles of camp. The morning of August 31 was dismal and overcast, with a heavy shower; in the afternoon the sky cleared; wind brisk, south to west; temperature, 47° to 74.5°. Several Caribou passed along the eastern side of Little River, and Fred Schweder, Jr., reported about 300 some miles north of camp, moving in a southwesterly direction. Clouds and rain ushered in the morning of September 1; the afternoon was sunny; wind light to strong, west to northwest; temperature, 48° to 60°. The next day was partly cloudy, with a mist squall or two; wind light to brisk, northwesterly; temperature, 38° to 51.5°. No Caribou were reported on either day.
