[obol] Ravens of Local Interest at Tryon Creek SP

[Norgren Family]

This is the second report of Ravens appearing
to nest on the urban fringe this week (Steve
MacDonald in Eugene the other). While quite
common west of Cornelius Pass Road in Washington
County they are decidely rare overhead in the small
towns of Forest Grove and Banks.
Sounds like the Saw-whet's nest box has been
pre-empted by a flying squirrel. Lars Norgren
