April 12 [Day 51] It was the warmest day so far this season with the temperature rising to 16C from a low of -1C, with cloudless skies until 1730 when up to 20% cirrus cloud developed. Winds were W all day, light in the morning and moderate after noon. The light winds meant that the first migrant raptor, an adult female Northern Harrier, did not appear until 1055 and movement was then slow but steady for the rest of the day with the last migrant, a juvenile Golden Eagle, moving at 1925. Of the 16 Golden Eagles, 3 were adults, 5 subadults and 8 juveniles. An unaged light morph Ferruginous Hawk at 1237 was the 7th of the season. A Tree Swallow was the 2nd of the year and the first butterflies were seen on the wing: 2 Satyr Commas and a Milbert’s Tortoiseshell. At the end of the day I checked the access road to the ridge but could only get halfway up it because of patches of thick snow so we shall continue to watch from the Valley View site for a few more days. 13.08 hours (569.3) BAEA 3 (384), NOHA 1 (6), SSHA 1 (6), NOGO 2 (84), RTHA 7 (122), FEHA 1 (7), GOEA 16 (2597) TOTAL 31 (3251)
Mount Lorette (Joel) There were similar weather conditions with the temperature ranging from -4C to 15C, generally 10-20% cirrostratus cloud cover and ridge winds moderate NW to WNW. The raptor count comprised 4 Bald Eagles (3 adults and 1 subadult) and 4 Golden Eagles (2 subadults and 2 juveniles) 13 hours (464.9) BAEA 4 (82), GOEA 4 (1175) TOTAL 8 (1283)
