Along the Whitemud Creek old coniferous forest tends to grow at the bottom of the ravine along the creek while deciduous forest tends to cover bank slopes. The deciduous stands consists of trembling aspen and balsam poplar trees along with white birch. These species are typically considered “pioneer” deciduous species, because they can establish and grow where there are not already many other trees. Coniferous trees, such as White spruce, on the other hand, are “shade tolerant”, and can survive and grow under a canopy of aspen/poplar. Eventually the spruce exceed the aspen and poplar trees in height and they become dominant in the upper canopy.
While winter is still holding our neck of the woods in a solid grip the temperatures have climbed up to more balmy temperatures after a few weeks of deep freeze. It is interesting to notice how a few week weeks of sub -30 C temperatures make the -20 C to -10 C range feel like spring. It appears the the birds feel the same way as they certainly seem to be more active. The snow is still covering the forest in a thick blanket but it is nice when birding is not a physically painful experience.
In the northern part of Edmonton, in an industrial area along a major highway there is a large grain terminal. Pigeons flock to the site as the spilled grain is an easy source of food, particularly in the winter. On any given day there are thousands of pigeons roosting on the beams and ducting of the large terminal building. As a result of the abundant food source (not the grain, but the pigeons) the site attracts birds of prey, such as gyrfalcon and bald eagles. I have been wanting to visit the grain terminal for a long time but it was not until this week that I managed to make it. It was a sunny and mild day and sure enough the pigeons were there. I spend most of my lunch hour carefully scanning the pigeons and the duct work on the grain terminal in the hopes of spotting a raptor, it with no luck. The only action I saw were kanoodling pigeons.
The view of the Great Horned owl from the boardwalk was perfect. After a while of admiring the Great Horned Owl basking in the sun I noticed a Red Squirrel sitting the snow covered railing. Considering the apex predator perching in the tree right across the creek it seemed like an ill-advised choice for a piece of fresh warm meat…, I mean squirrel to strut around right below the owl. I find it unlikely that the squirrel would be unaware of the owl. It is also possible that the squirrel is well aware of the owls diurnal habit of snoozing and that the tables turns after dark.
Pileated Woodpeckers hold a special place in my heart. Many years ago, long before I got into birding a friend of mine was sharing stories about his encounters with these magnificent birds. He was not a birder, he just had the fortune of seemingly bumping into Pileated Woodpeckers on a regular basis. I on the other hand, had no such luck. Through his stories and my lack of ability to spot Pileated Woodpeckers these birds became a legend. A seemingly unattainable mythical creature that continuously eluded me. It was only years later that I spotted my first Pileate Woodpecker. How things have changed. These days I not only see them on a regular basis, but I can identify them by sound, whether they are vocalizing or going to town on a tree. The sounds they produce are unmistakable. Spotting a Pileated Woodpecker is always a special treat, spotting two next to each other is an unforgettable experience. The other day two Pileate Woodpeckers were at work on the same tree trunk. Higher up the trunk a Northern Flicker was also busy working away. It must have been a particularly good woodpecker tree.
Next to a pair of hardworking Pileated Woodpeckers there was a solitary Northern Flicker working away on the same dead tree. Was it a coincidence that the two woodpecker species were at the same tree? Perhaps this a tree was particularly good for woodpeckers? Or perhaps the flicker was opportunistic and followed the Pileated Woodpeckers along through the forest taking advantage of the large gashes in the trunks the Pileated Woodpeckers leave behind? The Norther Flicker was illuminated by the late afternoon sun which made it particularly splendid against the blue sky. As the Pileated Woodpeckers moved on, so did the Northern Flicker.
On this sunny mild winters day we came across one of the Whitemud Ravine Great Horned Owls perching in a tree overlooking the creek. It was soaking up the suns rays and seemed fast asleep. I cannot blame it. After the last few weeks of bitterly cold weather the -10 C day must have felt nice and balmy. According to eBird the last time a Great Horned Owl was observed in the ravine was in October last year. Has the owl been there the whole time, but just not seen? Has it been somewhere else and only recently returned to this location? Is it alone, or does it have a mate? The owl we saw was close to a tree where a pair of Great Horned Owls raised a pair of owlets last spring. Is this one of those owls and is it back for another breading season? So many questions and no answers. I will be keeping a close eye on the owls in the ravine and hopefully we will see another season of successful owlets born and raised in our very own backyard ravine.
