This morning at 7:30am Carrie & I hiked up Tischer Ck attempting to find the Boreal owl listed Sat 2/23. Instead we found a rather shy Great Grey flying around mobbed by crows where the boreal was sighted previously. We think the Great Grey most likely was the cause of the boreal departing which was last seen here approx. 6 pm Sat. -J. Kelsey
