April 28 [Day 63] We finally made it to the ridge top to observe for the first time this season with the site snow-free but with several metres of snow packed on the lee side of the ridge. Even at 1900 m the temperature rose to 13.5C from a low of 6C, and it was mainly sunny with 30-60% cumulus cloud cover for most of the day. The wind was westerly all day gusting to around 40 km/h until 1715 after which gusts were in the vicinity of 70 km/h, and after 1615 smoke haze developed which lingered until the end of the day. Despite the wind it was good to be back up high and to appreciate again close views of migrating raptors, and there were fairly good numbers to see with 67 birds of 11 species (and 2 additional subspecies) moving: the 3rd highest count this month. The movement started late with only 4 birds seen by 1100 and the first Golden Eagle migrant didn’t appear until 1331 but then movement was steady until the passage of the last bird at 1854. The 5 Northern Harriers (all adults: 2 males and 3 females) was the highest count this season, and one of the day’s 8 Red-tailed Hawks was an adult “Krider’s Red-tailed Hawk” which glided close along the ridge at 1654 for a first site record. A juvenile light morph Ferruginous Hawk at 1405 was the 10th record of the species this season, and all the 22 Golden Eagles were immature: 4 subadults and 18 juveniles. The closest birds of the day, however, were the three resident Golden Eagles that glided by moving low to the north over the ridge at 1848, and despite much display by the male (or males) during the day, the female still shows little sign of nesting. Passerine movement along the ridge comprised 1 Mountain Bluebird, 2 American Robins and 83 Grey-crowned Rosy-Finches. 12.75 hours (715.8) OSPR 3 (14), BAEA 2 (430), NOHA 5 (19), SSHA 17 (92), COHA 2 (18), NOGO 1 (108), RTHA 8 (189), FEHA 1 (10), GOEA 22 (2820), MERL 3 (14), PRFA 1 (11), UU 2 (3) TOTAL 67 (3773)
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.
