May 1 [Day 66] Again the weather forecast was completely wrong and instead of rain it was a day of sunshine with the temperature rising to 5C from a low of -3C and a mainly WNW wind gusting to 30 km/h to ensure that the day was not too enjoyable. Cloud cover was cumulus, cirrus and cirrostratus gradually increasing from 5% early in the morning to 80% at the end of the day providing an excellent observing backdrop. Again there was no early movement and the first bird, an adult Northern Harrier, didn’t appear until 1056 and steady migration only started after noon after which it was steady until the last 2 Golden Eagles glided north at 1935. Many of the birds moved low overhead giving ample opportunity to study details of plumage. Immature Golden and Bald Eagles have dominated the flight for the last couple of weeks, but now young birds of other species are becoming more common with all 4 Red-tailed Hawks, 4 Northern Goshawks and 4 of the 17 Sharp-shinned Hawks being juveniles. All the 26 migrant Golden Eagles were immature: 6 subadults and 20 juveniles. The 3rd Broad-winged Hawk of the season, a light morph adult, flew low overhead at 1739. For the first time this season I observed a resident Golden Eagle carrying prey (probably ground squirrels) towards the west on two occasions, probably a male going to present food to the female: maybe breeding is getting closer! On the ridge Townsend’s Solitaires were anything but solitary as I counted 19 there, many of which were singing. For the first time there was a variety of finches moving: 46 Grey-crowned Rosy-Finches, 1 Pine Grosbeak, 2 Red Crossbills, 3 White-winged Crossbills and a single Pine Siskin. 13 hours (754.2) OSPR 2 (16), BAEA 2 (434), NOHA 2 (22), SSHA 17 (130), COHA 4 (22), NOGO 4 (114), BWHA 1 (3), RTHA 4 (201), GOEA 26 (2896), MERL 1 (17), PRFA 1 (13) TOTAL 64 (3929)
