April 4 [Day 43] At last, a spring-like day, with the temperature reaching 9C from a low of 0C, light to moderate WNW winds on the ridge and 100% thin altostratus cloud cover all day allowing hazy sunshine. Raptor movement was slow, starting at 1032 and peaking at 11 birds between 1200 and 1300 and tailing off thereafter with the last bird, the second Northern Harrier of the season, seen at 1838. The Golden Eagle count of 16 was the lowest for a non weather affected day since March 3. One of the 7 Red-tailed Hawks was an adult dark morph Harlan’s. The resident pair of Golden Eagles was in evidence all day with much vigorous displaying observed, but neither was seen to visit either of the nests. The day produced a season-high total of 31 bird species including 6 species of corvid: Grey, Steller’s and Blue Jays, Clark’s Nutcracker, Black-billed Magpie and Common Raven, and I saw the 7th Alberta corvid species, American Crow, just after leaving the site. 12 hours (466.2) BAEA 8 (337), NOHA 1 (2), SSHA 1 (4), NOGO 1 (67), RTHA 7 (58), GOEA 16 (2400), MERL 1 (6) TOTAL 35 (2907)

Mount Lorette (Des and Joan) The temperature rose to 8C from a low of 0C, cloud cover of cirrus and cumulus gave way in late morning to 100% stratus, and winds were light to moderate W until 1700 when a cold front from the north backed the wind to NW, obscuring the peaks with the arrival of snow. Two pairs of Golden Eagles moved at 1427 and 1635, in each case one was adult and the second bird disappeared into the cloud base before an age assessment could be made. The second pair was closely followed by 2 Peregrine Falcons, the first to be seen at either site this spring. 11.67 hours (392.4) GOEA 4 (1136), PEFA 2 (2) UU 1 (2) TOTAL 7 (1230)
