HOW DID WORLD RECORD BREAKER GET HIS GREAT GRAY?

November 28, 2015

Noah Strycker came to the expert when he wanted to add15. GGO Mother tree lichen 2195 IMG_5447 Great Gray Owl to his year list as he was on his way to setting his global record for most birds seen in a calendar year.  Noah has topped 5000 species.  Here’s his blog about finding Great Gray Owls with co-author Peter Thiemann.

ANOTHER PLATFORM REPORT

May 11, 2015

Another area of public land where there are nest platforms for Great Gray Owls is the Klamath Marsh National Wildlife Refuge in northeastern Klamath County, OR.  Faye Weekley, the biologist there, tells me one of her several platforms is in use this year and has a Great Gray Owl nestling.  As with the western slope of the Cascades and the Klamath Basin, Klamath Marsh seems to have an abundance of small mammals this spring.

Altogether that makes eight platforms in use across the state that I know of.
