Monday, September 24, 2007

September 24 [Day 28] The day dawned cloudless and cool (-1C) with 3 cm of fresh snow at the site. Cumulus cloud built up rapidly after 1100, and then decreased almost as rapidly after 1400 as the WNW to W winds increased from moderate to strong, finally gusting to 60 km/h after 1800 when the temperature finally made it to 5C. Raptor movement was very slow to start with only 7 birds passing before noon, but then got steadily stronger with 22 birds moving between 1800 and 1900 and, for the first time this season, 3 birds after 1900. Both Bald Eagle (5) and Golden Eagle (88) were the highest counts to date and eagle movement became stronger as the wind increased in the afternoon, whereas the accipiters moved earlier when the winds were lighter. Non-raptor movement was relatively light but included 84 American Robins and a late sapsucker. 12.67 hours (308.69) BAEA 5 (24), NOHA 1 (43), SSHA 18 (445), COHA 3 (134), NOGO 1 (21), UA 1 (49), RTHA 7 (125), GOEA 88 (288), PRFA 2 (11) TOTAL 126 (1216)
