The South Livingstone Raptor Count for the fall migration of 2007 has now begun. First official day of counting began on 25th August 2007. Follow the daily movement of raptors on this blog updated daily by Peter Sherrington.

Monday, December 10, 2007

December 9 [Day 100] The last day of the count saw strong NW winds all day gusting to 80 km/h in the afternoon, temperatures that ranged from -7C to -6C and 100% altostratus cloud that gave way to 70-80% lenticular/altostratus cover after 1500. The first adult Bald Eagle moved along the ridge at 1038 followed by 2 more at 1437 and 1447. The final bird of the count was another adult Bald Eagle gliding high to the south above the ridge at 1605: the 700th Bald Eagle and the 8289th migrant raptor of a very successful season.
This was the first year that the count has extended into December at the site and 6 days (47 hours) yielded a total of 78 migrant raptors: 69 Bald Eagles, 2 Northern Goshawks, 4 Rough-legged Hawks and 3 Golden Eagles. Doubtless a few Bald Eagles will continue to move south over the next couple of weeks but I had to leave for Calgary with Barbara on Sunday evening so she can start her radiation treatment on Monday. Next spring we shall conduct a full count at the Piitaistakis-South Livingstone site for the first time, starting around the middle of February, the exact date dependant on weather conditions at the time. 8.08 hours (1048) BAEA 4 (700) TOTAL 4 (8289)
