At this hour the moon, two days after "full," shed light of intensity ( ) suffi- cient to allow use of the field book without the aid of a flashlidit. Inci- dentally, the intensity was somewhat reduced by a pall of smoke that had been carried eastward some 2500 miles from extensive forest fires then devastating parts of Alberta. The moon's face wore an alluring pale saffron blush. At 5:15 the fight intensity of dawn ( ) had not attained that of the moon a half hour earlier. This deficit had been removed by 5:20 when the first call of a migrant. Figure 26. Migration of thrushes through pass from St. John Valley to Grand River Valley. thrush was heard. Three more birds piped at 5:25. None of these first 4 thrushes called often enough to determine the direction of flight, but at 5:27 a group of 8 was readily traced as it approached Station 1 from the origin of Second Fork farther westward, swung to the right overhead, and flew through the wooded pass toward Grand River. Although the courses of two succeeding small groups could not be determined, a flock of 7 birds also turned southward at 5:32. The next birds, a group of 10, passed down the Fork northeastward (5:33). Between 5:35 and 5:38, 70 were recorded, the majority of them veering through the pass. The first ground note was regis- tered at 5:39; 4 others had descended a minute later. By 5:43 their calls had Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Peabody Museum of Natural History.
