Great Gray Owl - from my archives

Crazy, crazy weather! We have only just come out of an awful deep-freeze that lasted for many weeks. "The chance for some +20 degree weather extends across southern Alberta and southwestern Saskatchewan early next week including the city of Calgary, where some daily temperature records are in jeopardy. The record to beat on Monday and Tuesday is 18.3°C and 18.9°C, which were both set on March 18 and 19 back in 1928." From the Weather Network on 16 March 2019.
I am going to be taking a break from posting photos on Flickr soon - decided to grab three photos to post this morning after all. Will return when I don't have to keep going into my archives. As I have been doing the last few days, I will add the description that I added under a previously posted photo from the same day.
"After a long day out at Frank Lake on Saturday, 19 March, and then checking the upcoming weather forecast, Sunday, 20 March 2016, looked like it was going to be the only decent day of the coming week. Of course, we all know that weather forecasts can change. So, my alarm clocks were all set ridiculously early, though I still left home a bit later than I had intended, and I took myself NW of the city again to see if I could see an owl.
Just a handful of friends were there and we got a few moments of great views of this Great Gray Owl, including when it was down on the ground during a failed attempt to catch a Meadow Vole. I think it took all of us by surprise when it flew and landed near to us. During the rest of the time, I did see an owl fly off into the trees a couple of times, but the rest of the time was spent waiting and chatting with my friends. Patience .....
While we were waiting, someone spotted a beautiful male Mountain Bluebird way down the road. I am pretty sure I had caught a quick glimpse of another Bluebird on my drive to my destination. Also, I seem to remember catching a quick sight of another one recently, but can't for the life of me remember where or when. It's always such a thrill to see a Bluebird, especially the very first of the season. That flash of bright blue takes one's breath away. Two beautiful birds to see on this first day of spring!"
"Although the Great Gray Owl is the tallest American owl with the largest wingspan, it is just a ball of feathers. It preys on small mammals and has relatively small feet. Both the Great Horned and Snowy owls weigh half again as much, and have larger feet and talons. The oldest recorded Great Gray Owl was at least 18 years, 9 months old and lived in Alberta."

This beautiful Great Gray Owl was amazing to watch, as it listened and watched for a Meadow Vole below the snow. Even when there might be several people standing watching the owl, it is completely focused, other than just an occasional glance in our direction. These owls are quite tolerant, for the most part, of people. Though it looks like it was very close and more or less at eye level, it was actually high in a tree. Normally, we don't get Great Gray Owls in Calgary - I think the last one was seen about 17 years ago, but this winter, we have seen two of them, one at Griffith Woods and the one in my photo, seen at Bebo Grove in Fish Creek Park. How very lucky we have been! The angle of the owl in my photo is not my favourite, but it does show the beautiful feather pattern on the back of the head and the rather flat facial disk.
A friend sent me the following information that she had received from Gus Yaki, a well-known Naturalist in the city, after asking him about the first of these two owls, seen at Griffith Woods. When asked about the possibility of the food supply having run out, he did not think the owl was feeding well because it was hunting during mid-day. It should have been hunting at dawn and dusk and sleeping during the day. He said they have excellent hearing. Also, he said he has not seen many small mammal tracks at this location and apparently the Meadow Voles have to surface to allow carbon dioxide to exit from their tunnels. He also said the owls see in ultraviolet which causes mouse urine to shine so they would see that.
"These birds wait, listen, and watch for prey, then swoop down; they also may fly low through open areas in search of prey. Their large facial disks, also known as "ruffs", focus sound, and the asymmetrical placement of their ears assists them in locating prey, because of the lack of light during the late and early hours in which they hunt. On the nesting grounds, they mainly hunt at night and near dawn and dusk; at other times, they are active mostly during the night.
They have excellent hearing, and may locate (and then capture) prey moving beneath 60 cm (2.0 ft) of snow in a series of tunnels solely with that sense. They then can crash to a snow depth roughly equal to their own body size to grab their prey. Only this species and, more infrequently, other fairly large owls from the Strix genus are known to "snow-plunge" for prey, a habit that is thought to require superb hearing not possessed by all types of owls."

Oh, my, what a face

I LOVE owls - but for some reason, the Barn Owl freaks me out, LOL! Just something about its face. Maybe it says the same about me, ha, ha! This Barn Owl resides at the Coaldale Bird of Prey Centre for injured birds, about 10 minutes past Lethbridge in southern Alberta. Takes just over two hours to drive there. We don't get Barn Owls in the wild here, so it is a great chance to see them down at the Coaldale centre.
