Project 366 – Post No. 214 – Owls vs beavers

What is Project 366? Read more here!

There is a rather unique tree down in the Whitemud Ravine. It is large and tall and half way up its trunk there is a l large cavity that has been used as a nesting cavity by Great Horned Owls for a number of years, most recently last spring. The other day I noticed that the base of the trunk had been wrapped in wired mesh. With the beavers coming back with a vengeance over the last few weeks it is hardly surprising that the city has tried to protect the tree. The City of Edmonton’s official policy on reducing beaver damage is to protect “high value trees” using metal mesh around the base of the trunk. As this is the only know Great Horned Owl nest it this part of the ravine this is definitely a high-value tree (see post 32). At this time of the year, the owls are nowhere to be see. One can only hope that the will be back next spring with a new batch of adorable owlets.

Project 366 – Post No. 056 – Great Horned Owlets

What is Project 366? Read more here!

I had never been down to the Whitemud Ravine in the morning before. Last Tuesday I was off from work and woke up early to a beautiful sunny morning. It was the perfect morning for a nature walk down by the creek. Said and done, at 7 am I started out down at the Snow Valley parking lot. Right off the bat, the birding kicked in at full gear with a bunch of Chipping Sparrows (Spizella passerina) hanging out in the trees by the parking lot. These were lifers for me and by playing their call through the Merlin App I had them sitting all around me in the trees curiously eyeing me. I can just imagine what must have been going though their bird brains, “Is this an intruder?” or “Is this a potential mate?”. That was a great start to a morning of some awesome birding. Other than two lifers, the highlight was definitely the Great Horned Owlets that were hanging out in their cavity. They were about 3 weeks old and getting quite large. By owl standards they would probably be considered teenagers. They sure behaved like teenagers, curious, oblivious to the dangers of the outside world, not following their owl parent instructions etc. There they were, perching precariously at the edge of the nest and ogling passersby. The sudden croaking of ravens directed their attention skywards. I am not sure if they would be aware of the dangers the ravens pose, but their parents definitely are. Dad, sitting in a nearby tree, started hooting and right away mom was inbound. She landed at the edge of the cavity pushing her owlets inside. The owlets had none of it as they tried to get past mom to check out what the commotion was about. Although the mother barely fit in the nest she blocked the entrance pushing her owlets back into the nest as she intently eyed the skies for the ravens. I spend well over an hour at the nest, snapping pictures and shooting videos of the chicks.

Below is a video clip (13:16 min) of the action at the nest. Mom arrives at 7:32 and the person you can hear talking and shooting pictures in the background is Wayne Oaks, the resident Whitemud Ravine birding afictionado.

All in all, it was an amazing and beautiful morning full of birds, two of which were lifers (Chipping Sparrow and the American Goldfinch). I could have continued but after 3.5 hrs and 6 km my stomach started to grumble so it was time for a second breakfast and more coffee. This experience has opened my eyes to the virtues of early morning birding. The weekend cannot arrive soon enough.

Here is the eBird summary of the morning.

Project 366 – Post No. 047 – Mother’s Day Owl

What is Project 366? Read more here!

The female Great Horned Owl down at the Whitemud Ravine has now been holed up in her tree for 2 months (that’s 60 days folks). There is reliable intelligence (i.e. picture evidence) showing that her eggs now have hatched and that she has at least two adorable fuzzy chicks. I went down to check out the new family on Mother’s Day (last Sunday). It was a beautiful and sunny spring day and lots of people were out on the trails. The trail was busy with adults and kids walking and biking, dogs taking their owners for a walk and the occasional mandatory fitness buffs. I was surprised to find no other birders or photographers were at the nest site. Mom owl was in her nest, with her tail feathers sticking out. Dad owl was nowhere to be seen but the occasional hooting from inside the forest provided reassurance that he was around. I set up my gear and got to try out my new ultra-portable tripod, the JOBY GorillaPod 3K Video PRO with the Nikon P1000. As my mode of transport was my bike I did not want to pack the full sized tripod. The GorrillaPod performed commendable and had no trouble managing the hefty P1000. Of course a lone photographer with a camera pointed skyward attracts attention and it was not long before I had quite a gathering of spectators squinting against the bright sky trying to figure out what I was photographing. Everyone gets super happy and impressed when they are told about the nest with Great Horned Owl mom and her chicks. Owl mom seemed to be sleeping until an overly excited dog came running down the trail, barking and yapping like its life depended on it. Immediately a big yellow eye appeared in the nest scanning the horizon watchfully. She owl did not move a feather but her ever watchful eye was keeping close tabs on our activities below. I did not see the chicks that day, but I spend a long time at the nest taking photos, watching for the dad (which I never spotted, only heard) and talking to people about the owl family. Today’s photo was shoot through the emerging foliage. Your can see a few fuzzy green blobs of leaves bursting out after a long winter.

Project 366 – Post No. 032 – Great Horned Owl family update

What is Project 366? Read more here!

The secret is out, someone saw one of the Great Horned Owl chicks peaking out of the nest the other day. I am obviously talking about Edmonton’s own celebrity owl family down in the Whitemud Ravine. Last time I was down there, four days ago, mom owl was still in her cavity. I did not see any chicks but mom was peaking out of the nest and she seemed to be “higher up” in the nest, perhaps indicating that there are growing chicks below her. While this is exciting news, I am a bit concerned about the well-being of this celebrity family. Just like any celebrity family, they are under close scrutiny of the public with eager paparazzi nature photographers and birders watching their every move. There always seems to be photographers at the nest. To anyone regularly trafficking the trail it would be completely obvious that there is something interesting hiding in the trees. So far, everyone seems to be mindful and considerate of the feathered family, but it only takes one bad apple to cause irreparable harm. There are good reasons why eBird does not allow the publication of the exact location of owl nests. Owls are vulnerable to disturbances not just from humans but also from other birds. For example, owls are commonly harassed by other birds. If other birds, such as crows, ravens and other raptors, get alerted to the presence of the owls they could start harassing them or even prey on the young. Perhaps one could view all the nature loving photographers and birders as standing on guard around the family, making sure they are not bothered by anyone with ill intentions. I know that I will be back at the nest, carefully and mindfully observing the family from a distance.

Project 366 – Post No. 010 – Great Horned Owl on Eggs

What is Project 366? Read more here!

The female Great Horned Owl in Whitemud Ravine is on her 29’th day sitting the eggs. We have been down checking in on her several times a week in the last little while and she is always in her nest. The male is always on guard in a nearby tree. In this picture you can see her feathery rear end and the back of her head with the two characteristic “horns”, which are actually tufts of feathers. The significance of the horns is not fully understood but it is believed they are used in social interactions. The owl couple is always very chilled when we are around (which is during the day) and one can always see Red Squirrels defiantly romping around in the understory right below the owls. I suspect the tables are turned once darkness falls. I have entertained the idea of heading down to the owls at night. The next full moon is on March 20. Let’s see if I can convince anyone else to joint me on a night time nature walk.

Project 366 – Post No. 004 – A Celebrity Couple

What is Project 366? Read more here!

If you spend any time down in the Whitemud Ravine, whether you are a birder, dog walker or fitness buff, you soon realize that someone is hiding high up in the trees along the trail. It’s an expecting pair of Great Horned Owls. They are discrete and quiet with the female hiding in a large tree cavity while sitting on eggs and the male, always close by, hiding among the branches high up in a nearby tree. You could easily walk by them not realizing they are there. The only reason one cannot miss them is because of all the photographers hanging out by their nesting site. These owls are truly a celebrity couple with paparazzis-style nature photographers and nature buffs breathlessly watching their every move and counting the days the female has been sitting on the eggs. Apparently today is day 23. Great Horned Owls incubate their eggs for about 30-37 days which would give a predicted hatch date somewhere between April 8 and April 15. With the Whitemud Ravine being the closest birding hotspot for us, we typically head down to the creek several times a week. It is always exciting, refreshing and suspenseful as you never know what you see or who you bump into, birds, animals or fellow nature buffs. On our walk yesterday I managed to snap the following picture of the male. He seemed tired and could not care less about the photographers below the tree. For a moment a feisty Black-capped Chickadee tried to get his attention, but he dismissed the diminutive critter like it would be nothing more than a buzzing mosquito. The chickadee deserves our respect though. It takes some big cojones for someone that small to pick a fight with someone that much larger with those formidable talons and beak.

Owling in the Frozen Wilds

This year’s Family Day weekend coincided with the Great Backyard Bird Count so obviously this called for heading out into the wild for some birding with family and friends. For the past three weeks, however, Alberta has been under, what appears to be, an unbreakable cold spell. The normal seasonal temperature this time of year in Edmonton is around -10 °C, but all through February temperatures have hovered around -30 °C…, and that is without taking the windchill into account. With the windchill, night temperatures have dropped down to between -30 °C to -40 °C. Needless to say, birding has been put on the back burner during this cold spell.

The current cold snap is almost in on its third week. The wind chills often push the temperature down another 10 °C to 15 °C.

After three weeks of increasing cabin fever, it was decided, it was time to brave the deep freeze and head out in the frozen wilds. We ended up doing two excursions over the weekend, one to Ray Gibbon Drive in St. Albert in search of our first Snowy Owl and a second to the Whitemud Creek for some general winter bird awesomeness.

Ray Gibbon Drive is a major thoroughfare with lots of traffic and I would have never expected for such a large owl to be hanging out in plain daylight in such a busy and mundane location. We had, however, received reliable intel from a fellow birder that Snowy Owls can often be seen perching on the light and utility poles along the road. So it was with anticipation and mounting excitement we headed north to Ray Gibbon Drive on Sunday. The heavy traffic and the lack of shoulders do not allow a car to stop so our strategy was simple. Drive as slowly as possible, but not so slow that drivers behind us would lose their cool (which would be indicated by honking and visible fists in our rear mirrors)…, while systematically scanning the roadside for owls. We figured that at a slow enough speed and with three pairs of eyeballs it would be difficult for an owl to go unnoticed. If we did not spot an owl on the first pass, we would drive to the end of the road, turn around and do another pass…, and repeat as long as necessary. As it turned out, luck was on our side. On our first pass, we spotted a large “poofy” organic-looking mass on the cross arm of a wooden utility pole. We decided to try to get a better view, so we pulled off the main road, parked at a gravel road and ventured into the Grey Nuns Spruce Woodlot. The good news is that after a bit of a hike we were able to get a clear view of the owl from a distance. The not so good news is that the cold got the better of us and we had to cut the birding short and as we do not have a camera yet we were not able to get a picture of the owl. The specimen was a large white snowy owl that looked completely at ease on its perch, despite the heavy traffic close by.

This sighting is special for us. Not only is it a lifer for all three of us but it is also our very first owl! One cannot help but be in awe of such a magnificent bird on a blisteringly cold winter day such as this, particularly when you consider that they migrate south to Edmonton to overwinter.

Reported Snowy Owl sightings along Ray Gibbon Dr between December 2018 and February 2019. Yup – the owls are definitely there!

The following day we ventured to Whitemud Creek. Over 150 species of birds have been identified along this creek, making it somewhat of a birding hotspot due to the riparian habitat and abundance of old growth forest with dead standing trees. Despite the biting cold we saw all the regular inhabitants of the area, from the bold and chatty Black-capped Chickadees demanding sunflower seeds, the odd White-breasted Nuthatch to a timid Downy Woodpecker and a splendid Pileated Woodpecker that could not care less about us ogling him as he was working away on a tree stump with such ferocity woodchips were whirling around him like there was no tomorrow. The highlight, however, was undoubtedly the Great Horned Owl pair we found, with the female snuggled up in a large cavity in a dead tree and the male hiding among the low-level branches of a nearby spruce tree. The pair, silent and perfectly camouflaged blended in with the bark of the trees. How did we find them? We just followed the throng of primates carrying cameras with large telephoto lenses. It turns out that the owl pair is a bit of celebrity for people that regularly visit the creek.

All in all, the weekend’s birding did not become memorable for the sheer number of species but rather for the two iconic and majestic owls that both were lifers as well as our first two owl species. With the addition of these two owls, our Alberta Big Year tally is now at 40 species. Here is the full tally of our sightings for these two days.
