April 16 [Day 55] At -8C it was the coldest start since April 2 but it warmed up to 7.5C and it was mainly a pleasant day. Ground winds were very variable but the wind at ridge level was WNW moderate to strong all day, and cloud cover ranged from 5% cumulus early in the morning up to 100% cumulus, altocumulus and cirrus at noon. The first bird, a subadult Golden Eagle, did not appear until 1000 but subsequent movement was fairly steady until 1952 when an adult male columbarius Merlin flew north. The day’s only Bald Eagle at 1631 was the 400th of the season, and an adult light morph Ferruginous Hawk at 1347 was the 9th so far. The 26 Golden Eagles is the highest count in a week and comprised 2 adults, 7 subadults, 16 juveniles and 1 unaged bird. The resident Golden Eagle pair was again conspicuous for much of the day, often in the company of a tolerated third adult bird. At 1325 both the male and female visited the Bluff Mountain nest each for about 6 seconds 10 seconds apart: the first observed visit since April 5. At 1944 the residents were soaring high with the third adult to the SSE when the pair locked talons and fell while continuously rotating, disappearing behind a ridge. This is the first time I have observed this unusual courtship display in this species. Obvious passerine movement was confined to 220 Grey-crowned Rosy-Finches moving north in 3 flocks. 13.17 hours (619.9) BAEA 1 (400), COHA 2 (4), NOGO 1 (92), RTHA 5 (135), FEHA 1 (9), GOEA 26 (2643), MERL 1 (7) TOTAL 37 (3349)
