February 23 [Day 4] Another pleasant day with the temperature rising from -1C to 6C, but moderate westerly winds made it feel cooler. The upper flow was strong westerly to 1300 producing variable cirrus and altocumulus cloud that diminished to 5% from 1200 to 1330, but progressively increased to 100% cumulus by the end of the day as a light northerly flow aloft became established after 1330. With moderate westerly winds I was expecting an early start to raptor movement but the first migrant, a juvenile Golden Eagle (the only immature bird of the day), did not pass until 1151. Thereafter movement was fairly steady (for February) until 1642 when the day’s 17th raptor and 10th Golden Eagle went north. The day’s Golden Eagle total equals the earliest double-figure count for the species, which was
The South Livingstone Raptor Count for the spring migration of 2008 has now begun. First official day of counting began on 20th February 2008. Follow the daily movement of raptors on this blog updated daily by Peter Sherrington.
