Monday, December 7, 2009

December 7 [Day 101] (Valley View site) It was the coldest day of the season with a temperature high of -18C from 1200 to 1420 from a low of -29C and by 1700 it was down to -25C again. Ground winds were NE to NNE gusting to 15 km/h until 1100 after which they mercifully became light SW to W, and ridge winds appeared to be light or moderate NE to N all day. Skies were essentially cloudless all day with only occasional traces of ephemeral cumulus cloud in the afternoon. A total of 9 raptors migrated between 1136 and 1404 comprising 7 Bald Eagles (6 adults and 1 subadult), 1 adult intermediate morph “Harlan’s” Red-tailed Hawk and a juvenile Golden Eagle. The Harlan’s Hawk is the first ever December record for a Red-tailed Hawk on a RMERF count and was the first at the site since November 4, and the Golden Eagle was the latest ever recorded at this site. With the exception of one adult Bald Eagle seen over the Livingstone ridge, all the birds moved south over Bluff Mountain to the west of the observation site. A single Townsend’s Solitaire seen on a couple of occasions was the latest ever recorded on a count here. 9.75 hours (1126) BAEA 7 (682), RTHA 1 (195), GOEA 1 (4293) TOTAL 9 (7143)
