May 2 [Day 67] It was a rare calm day on the ridge with no significant wind until after 1400 when it briefly gusted from various quarters to 15 km/h. The temperature rose to 10.5C from a low of 0C, and 20-60% cumulus cloud cover for most of the day made locating birds relatively easy although unlike yesterday few were close to the ridge. Movement was very sporadic with most birds moving during periods of SW winds, with a period between 1225 and 1510 with no movement at all. Notable were the 4th Broad-winged Hawk (adult light morph) and 13th “Harlan’s” Red-tailed Hawk (adult dark) of the season and all 11 migratory Golden Eagles were immature, 1 subadult and 10 juveniles, the last of which came through at 1911. When I arrived at the ridge top the site was occupied by 6 Dusky Grouse and males were heard hooting throughout the day. New species for the season were Savannah Sparrow and a singing Ruby-crowned Kinglet, and Tree Swallow and a winnowing Wilson’s Snipe were recorded for the first time from the ridge. At 1008 a Blue Jay and a Steller’s Jay flew together to the west. 13 hours (767.2) NOHA 2 (24), SSHA 5 (135), COHA 1 (23), NOGO 2 (116), BWHA 1 (4), RTHA 1 (202), UB 1 (4), GOEA 11 (2907) TOTAL 24 (3953)
