Not only did the French women’s soccer (they call it football) lose to the USA, but the nation saw its highest ever recorded temperature today. In southern France one town recorded 45.9 degree Celsius (centigrade). Quick conversion for us Yanks, 9/5 x C, plus 32…and you get a Fahrenheit temp over 114 degrees. Even down in the oven Sahara they would find that to be warm…and that;s where this weather has come from.

October 5, 2018GREAT GRAY OWL RANGE MAPS FOR PACIFIC SLOPE
June 30, 2016Here are the range maps from our Great Gray Owl book, feel free to use and copy. Please give us credit as these are original maps based on our research. I hope in twenty years new maps will show that there are owls in some of the interstices and that the species is thriving. Much of this information came from direct witnesses including many helpful biologists with federal and state agencies.
We have provided much needed information for the wikipedia entry on this species, Check it out here.
GREAT GRAY OWL VIDEOS
April 4, 2016There is a series of four Great Gray Owl videos taken in March, 2016, near Howard Prairie in the Cascades east of Ashland, OR. A blog on my birding site has links to each of the videos, including one showing the mated pair preening one another.

Avian keratin disorder:
http://atowhee.wordpress.com/2014/08/14/freak-beak/
I am investigating an epizootic of similar bill deformities in Alaska. This epizootic has recently spread to the Pacific Northwest, with a large cluster of bill deformities appearing in the Puget Sound region. Birds affected by this ‘avian keratin disorder’ have bills that are abnormally long and often crossed, such as in this nuthatch. We’ve determined that the keratin layer of the beak (like the material in a person’s fingernails) is growing too rapidly. Despite extensive testing, we still don’t know what’s causing the problem. We’ve documented beak deformities among a large number of species, including chickadees, crows, nuthatches, jays, woodpeckers, ravens, and several raptors. We are very interested in receiving reports of any birds with abnormal bills such as this one. Please visit our website at the USGS Alaska Science Center or contact me directly:

GREAT GRAY OWL NEST RESEARCH IN CALIFORNIA
August 19, 2015Here’s link to site about my book on the Pacific Slope Great Gray Owls.
The Institute for Bird Populations has just published a study of all known Great Gray Owl nest sites in Yosemite area of the Sierra Nevada. Here is the official citing for the article: Wu, J.X., R.B. Siegel, H.L. Loffland, M.W. Tingley, S.L. Stock, K.N. Roberts, J.J. Keane, J.R. Medley, R. Bridgman, and C. Stermer. 2015. Diversity of nest sites and nesting habitats used by Great Gray Owls in California. Journal of Wildlife Management 79:937-947.
It cost me $38 to see the whole thing so I will give you a summary.
As I found when writing my Great Gray Owl book this species is NOT a strictly montane bird, nor is it confined to conifer forests. It may now be most likely there because we humans have driven them out of valleys and more oak-dominated terrain like the Sacramento and Willamette River Valleys where they may have nested three centuries ago.
One-fifth of the nests in this study were found below 1000′ in elevation.
30% of nest trees were oaks, large oaks, within conifer stands.
The GGO prefers well-rotted trees beneath a fairly dense canopy. Message to land managers: don’t rip down all your old, rotting oaks or Doug-fir.
Many of the preferred nest snags lasted about five years after the first nesting use. Good naturally occuring nest trees are ephemeral
Slowly deteriorating trees like incense-cedar and sugar pines are not used for nesting.
This study included no man-made platforms which are frequently used by Oregon populations of GGOs, both in the Wallowa Mountains and southern Cascades.
This study covered 56 nest sites in the California Sierra confirmed between 1973 and 2014. The southernmost one is on the Tulare-Fresno County border. That’s the southernmost GGO nest in the known world.This picture shows female with owlet in nest that was probably originally built by Ravens, not in a rotted out, broken tree trunk as most often found in Yosemite area. The pictured nest was used only once in the southern Cascades of Oregon. One of the two owlets survived fledging from this nest in a ponderosa.
GREAT GRAY OWL PRESENTATION
July 27, 2015I will be giving a talk on Oregon’s Great Gray Owls in Ashland next month. Here’s the press release from the Ashland Library:
Harry Fuller “… will be discussing his book and tales of birding on Thursday, August 13 from 7:00 to 8:30 p.m. at the Ashland Branch Library, 410 Siskiyou Boulevard.
“Great Gray Owls are one of the most mysterious and sought-after bird residents of California, Oregon, and Washington. Even though it is the tallest owl in North America, and notoriously approachable by humans, the Great Gray is hard to find. Biologists surveying for other species may happen accidentally on the owl, but finding it intentionally isn’t easy due to its nocturnal habits, excellent camouflage, and silent flight. Despite high breeding concentrations in the Wallowa Mountains of Oregon, Great Grays are of conservation concern to wildlife managers in Oregon due to declines in the overall population and loss of habitat.
“Fuller is author of Freeway Birding, San Francisco to Seattle, about birds found within 20 miles of interchanges. He has taught numerous classes at the Klamath Bird Observatory, Osher Lifelong Learning Institute, and North Mountain Nature Park in Ashland.
“This program is sponsored by the Friends of the Ashland Public Library. For more information, please call contact the Ashland Branch Library at 541-774-6996 or visit jcls.org.”
The photo is this blog was taken by Andy Huber on his ranch near La Grande, Oregon. Huber has been helping a widowed female owl feed her four fledglings. He has been live-trapping small mammals and releasing them near the adult and young owls so they can re-catch their prey. They will not eat animals previously killed.
SURROGATE FATHER TO A FAMILY OF GREAT GRAY OWLETS
May 28, 2015Rancher, conservationists and owl-lovers, Andy Huber and his wife are co-parenting a family of Great Gray Owls. The Hubers own a ranch near Le Grande in northeastern Oregon’s Blue Mountains. This spring a couple of GGOs began raising a family. One tragic morning the Hubers awoke to see Great Gray Owl feathers scattered on the ground…overnight a Great Horned Owl had killed and eaten the male GGO. That left a widowed GGO with a nestful to raise. The Hubers pitched in. Friends loaned them live traps with which to catch small mammals. The adult female quickly learned to grab the offered prey. Many weeks of maturing are ahead of the fledglings but the Hubers persist. Here is a selection of photos of the Huber owls:
There is a quartet of owlets in this family and each can eat four small mammals per day, that’s a lot of huntin’ and trappin’ … for weeks. These youngster will not be effective hunters until very late summer at the earliest. Most abundant prey at that spot right now is kangaroo mice.
My new book on Great Gray Owls of California, Oregon and Washington is now available. Order yours direct from me, $28 plus shipping, over 100 photos and original range maps. More on earlier blog on this website.
SUCCESS STORY OUT OF LA GRANDE, OREGON
May 10, 2015I hear from Laura Navarette of the Whiteman-Wallowa National Forest that their field biologists have confirmed six nesting pairs of Great Gray Owls in their thirty-plus nest platforms in the forest. I will be out in La Grande later this week to give a talk on Great Gray Owls in Oregon and the Pacific Northwest. The talk will be at the dinner for the Ladd Marsh Bird Festival there on Friday.
The Spring Area north of La Grande has the largest and longest-running GGO nest platform program anywhere in the U.S. It’s success is heartening. In our new book on Great Gray Owls, Peter Thiemann and I have included a chart through last spring of the nest platform use rate in Spring Creek. Eight active platforms is the most in one year so far. Occasionally none of the platforms get used. That probably has to do to springs with little or low prey availability. This past winter was wet and mild in the Blue Mountains. That may have spurred the local rodents to greater and earlier reproduction as they would have found plenty of plant food.
Here in Jackson County Rogue Valley Audubon is accepting donations to put up more platforms…so far local birders are monitoring 11 platforms most just erected last fall and winter. We know of at least one successful platform-nesting pair so this far. We’d like to get up more platforms in the coming fall.
For further information on the Spring Creek Great Gray Owl Management Area near Legrande, click here. Harry Fuller will be leading a trip into the area at the Ladd Marsh Festival Saturday morning.
