September 13 [Day 19] There was essentially a cloudless sky all day with only traces of cumulus cloud between 1000 and 1500. The clear sky allowed the temperature to drop below freezing (-1C) for the first time this season but by 1400 it briefly reached 11C. Winds were light (<15 km/h) all day, initially from the west, then E to ENE after 1600. Because of the conditions raptor movement occurred both to the east and west, as well as over the ridge and the blue sky made detection challenging, although with the help of Vance, making his first visit to the site this year, we managed to amass the first three-figure count of the season: 114 migrants. Seasonal high counts were made of Sharp-shinned Hawk (53), Broad-winged Hawk (2: both juveniles) and Golden Eagle (20), the first significant movement for this species. The 10 Red-tailed Hawks equaled the season high and included 3 “Harlan’s Hawks” one of which was a juvenile intermediate morph. For the first time a significant number of adult accipiters were moving: 10 adult Sharp-shinned Hawks and 9 adult Cooper’s Hawks. A juvenile Northern Harrier narrowly avoided becoming a meal itself when it just avoided a stoop by the resident juvenile Golden Eagle at 1710. After yesterday’s weather, passerine movement was predictably light, but included the first Pine Grosbeak and Bohemian Waxwing of the season, perched on adjacent trees just after 0900, and our first ever Harris’ Sparrow skulking under a krummholtz Douglas Fir at 1825, the 75th bird species of the season. 12.08 hours (209.01) OSPR 1 (6), NOHA 4 (36), SSHA 53 (252), COHA 16 (83), UA 6 (28), BWHA 2 (8), RTHA 10 (77), FEHA 1 (4), GOEA 20 (46), AMKE 1 (32) TOTAL 114 (602)
