September 4 [Day 11] Winds were WNW gusting to 50 km/h until 1600 when they backed to W and moderated to less than 30 km/h. It was again warm with temperatures ranging from 15 to 22C, and altostratus and cumulus cloud cover varied from 20-90% causing observation difficulties with high-flying birds at the lower end of the range. The first migrant raptor was not seen until 1108 and the last moved at 1834, the latest yet this season. The combined species total of 53 was the highest of the season, with the main movement between 1200 and 1600. Most birds were moving high and all but one were west of the ridge. The total included season high counts for Northern Harrier, Cooper’s Hawk, Red-tailed Hawk and American Kestrel and equaled the high for Sharp-shinned Hawk. Season high counts were also established for Red-breasted Nuthatch (32) and Yellow-rumped Warbler (85) with steady southward flow over most of the day, and a single Evening Grosbeak flying south with robins was the 60th species of the season and a new species for the site. 12.33 hours (117.33) NOHA 6 (11), SSHA 16 (52), COHA 9 (27), UA 6, BWHA 1 (3), RTHA 10 (36), GOEA 1 (6), AMKE 4 (14) TOTAL 53 (176)
