April 5 [Day 48] (Valley View site) Ground winds were variable and light all day, ridge winds were light to moderate W, cloud cover was mainly 100% altostratus and altocumulus and the temperature reached 9C at 1300 from a low of -7C. Despite what appeared to be reasonable migration and observing conditions, only 4 migrant raptors were seen: 1 juvenile Bald Eagle, 1 adult light morph Red-tailed Hawk and 2 Golden Eagles (1a,1sa) that moved between 1106 and 1534. 11.5 hours (558.1) BAEA 1 (332), RTHA 1 (41), GOEA 2 (1961) TOTAL 4 (2463)
Mount Lorette [Day 36] (Jim Davis) Weather condition were almost identical with the temperature reaching a high of 10C at 1400 from a low of -9C, ground winds were light W and ridge winds light to moderate SW all day, and cloud cover was altostratus and altocumulus thickening to 80% in the afternoon. Raptor migration, however, was much better and probably represented birds that passed P-SL yesterday afternoon, with 14 of the day’s 22 Golden Eagles (10a,3sa,3j,6u) moving across Mount Allan to the west of the site. Two Adult Bald Eagles and an adult light morph Red-tailed Hawk completed the count of 25 birds, most of which moved in the morning and early afternoon, with none recorded after 1700 as snow developed south of the site. An unusual interaction in the afternoon saw a resident adult Golden Eagle perched on a crag near Olympic Summit on Mount Allan flushed by a passing Grey Wolf, the eagle returning to its perch after the wolf had gone. 12.42 hours (409) BAEA 2 (76), RTHA 1 (7), GOEA 22 (1112) TOTAL 25 (1239)
The Piitaistakis (South Livingstone Ridge)and Mt. Lorette Raptor Counts for the spring migration of 2010 are underway. Follow the daily movement of raptors in these field notes by Research Director Peter Sherrington and his citizen scientist colleagues.
