Observers: Naia West

Visitors:
37

Weather:
-3 C to +12 C. 90-100 % altostratus to 14:00, then 90-100 % altocumulus. Ground winds mostly south 2 to 10 km/h, occasional gusts to 20 km/h. Ridge winds SW to WSW 30 to 60 km/h. Some negligible precipitation around 18:00.

Raptor Observations:
The cloud background made aging difficult, and many eagles were aged when they passed in front of rock for a dark background. 50 migrant raptors consisting of 1 unaged Sharp-shinned Hawk, 2 unaged Cooper’s Hawks, and 47 Golden Eagles (22a, 7j, 18u). Also one non-migrant Osprey flying north with a fish, and one non-migrant adult Golden Eagle flying north.

Non-raptor Observations:
American Dipper 1, American Robin 40, Belted Kingfisher 1, Northern Flicker 2, Common Merganser 3.
Interesting observation: a “dogfight” between a raven and a juvenile Golden Eagle that continued non-stop for several minutes from Patrick all the way to Mt. McDougall, with the raven sometimes on the attack and and even making contact, and the eagle sometimes wildly chasing the raven, with the raven staying 20 to 50 cm ahead of the eagle (estimate based on the size of the raven). In front of McDougall, the eagle finally put on a burst of speed and left the raven behind.
