Peak Birding – The Great Horned Owl

Dec7

By Cathy Warwick

A few weeks ago I was leaving my house to start my walk to work and I saw a cloud of Magpies squawking wildly around a spruce tree. I ran over and was delighted to see a large Great Horned Owl! It was a lighter color than I had seen before, almost white. Its large yellow eyes looked at me wearily. The Magpies were relentlessly hassling it, flying at it and generally freaking out. I managed to get a fairly decent picture of it with my phone, and also yelled at a stranger “An Owl is in this tree!”, as one should given the special circumstances. If I saw an owl nesting I wouldn’t tell anyone, but I could tell this one was moving on soon.

The Magpies know the owl is a skilled predator that is a threat to their very lives, they don’t want it to get comfortable in our neighbourhood. Owls have very sharp beaks, crushing claws, night vision, great hearing and near silent flight, they must be terrifying to other birds. Whereas we humans just notice their super fluffy feathers and luminous, intelligent eyes. “Don’t be mean” we mutter to the Magpies and Crows harassing them.

Owls eat rodents, hares, skunks and other mammals. With their swiveling head, which can turn nearly 180 degrees in either direction, no small mammal is safe. They’ve even been known to go after house cats. I would love to see one hunting, I wouldn’t hear it though. There are numerous videos on the internet of an owl flying with a sound detector nearby, they are virtually silent. They have specialized feathers that break up the sound, a subject of much study by scientists.

If you see a very large owl it is probably one of three in Calgary: Snowy, Great Grey or Great Horned. The Great Horned Owl is the most common and is distinct because of its prominent ‘horns’ which are part of a ‘V’ coming down to its beak. Although the Long Eared owl also has feather tufts protruding from the top of its head, those owls are much harder to find in the city. Obviously the same person didn’t name these owls, one taking their tufts for horns and the other for ears. It is difficult to identify owls by colour (other than the Snowy of course), for instance the Great Horned can vary from a light colour to a tawny brown colour. 

Nesting for the Great Horned is in February. The mating pair will usually steal another bird’s nest, they aren’t the apex of the birding world without some perks! After laying the eggs the female will diligently keep the nest warm for about 30 days. It probably requires a lot of energy – warming eggs through those long cold nights. Once the fluffy little owlets hatch they will stay around the nest until fall. If you know where an Owl is nesting, keep it to yourself and give them a chance to make it through their long nesting cycle.

I’m not sure if I’ll see the Owl around my house again, the Magpies are a very dominant force on our street. They seem really smug about it, if they had fingers they would be snapping them like the Jets from West Side Story. Meanwhile the owl has moved on, although they don’t migrate they can travel far for food, or to get away from Magpie gangs.

Merry Christmas and Happy New Year everyone! May you all see an owl this season.

Winter Bird Lists, 2025-2026

Dec5

Tracking the winter birds of Alberta from December 1 to February 28.

Posted by Bob Lefebvre

It’s time for winter birding, and I will be helping to track the species seen in the Calgary area once again. Caroline Lambert provides a lot of assistance with the Calgary list, and also maintains the Bow Valley list.

Caroline also maintains a website with up-to-date and historical data for each of the four lists. Here is more information on the lists, from Caroline:

Link to The Winter Bird Lists.

Calgary: The count area is the 80km radius count circle centred on Calgary, the same one used for the May species count. It is preferred that sightings during this count period and in the count area be reported to the email list, albertabird@groups.io (keeping in mind that certain sensitive species should not be openly reported), but we will also include species reported to eBird and elsewhere, if we can find them.

Bow Valley: this area includes both the Bow River and Kananaskis River watersheds, as far east as the Stoney Nakoda casino and Seebe Dam. Most sightings for this area are taken from the Bow Valley Birding Facebook group, but we will record sightings reported on this email list, Albertabird, eBird, Christmas Bird Counts, rumours on the street, etc. The Bow Valley has the lowest species count of any area, so we’ll accept any reputable report! This is the list Caroline maintains, so you can send reports of sightings to her.

Provincial list: Andy Ross is again taking care of the Alberta-wide list. Andy will collect sightings from the usual sources (eBird, Albertabird, the other winter lists, WhatsApp, etc.). 

The Edmonton list as shown on the albertawinterbirds.org site is kept by Vivek Dabral. Birds that are listed on the Edmonton list must be reported to the Edmonton Nature Club discussion group (ENCnaturetalk@groups.io) by an Edmonton Nature Club member. If you are in Edmonton and are interested in the club, more information can be found at edmontonnatureclub.org.

If you post your sightings to eBird it will be added to the appropriate list (except for the Edmonton one). If you see a significant species that has not already been found, you can report it as above, or email to birdscalgary@gmail.com.

Most of the common winter birds are found on December 1st or shortly thereafter. This year, we had 63 species on the first day in the Calgary circle. As of December 4th, we are at 75 species. Our average for the winter is 113, so there are still lots of birds to find!

Notable birds include a Spotted Towhee which was found on December 1st in Redwood Meadows (and had been there for a while). It is only the second Calgary winter record in the nine years of the count. If you are building your own winter list, you might want to head to Carburn Park for the Harlequin Duck, which has only been reported there, and for some uncommon ducks. Wilson’s Snipe has only been reported from Douglasbank Park. Brown-Lowery Park has again produced an American Three-toed Woodpecker, and is a good place to try for Black-backed Woodpecker as well (not seen yet).

As of December 4th, the list totals are: Alberta 97, Calgary 75, Edmonton 43, Bow Valley 32.

I’ll do an update with more sightings and missing targets in a week or so. Good winter birding!

Count Birds in Your Yard For the Christmas Bird Count!

Nov30

Spend 30 minutes counting birds on December 14th for the Calgary CBC.

We always like to have as many birders as possible go out in the field on Count Day, and this is how we get the majority of our birds and species. But field teams operate mostly in parks in the city (though we do have some diligent counters who drive residential back alleys!), and there are large areas of the city that are not covered in this way . That’s where the Feeder Watchers come in.

As a Feeder Watcher, you simply count the birds you see in or from your yard on Count Day. We ask that you spend at least 30 minutes counting in total, though you can spend much more time if you wish. Every year our Feeder Watchers see a good number of species, including usually one or two that are not found by the field teams. So they are an important part of the Count, and they do help to fill in the gaps in our coverage.

We can really use more people to watch at their feeders this year. If you have participated in the past, you still have to register this year to be included.

Register here!

Below is an animated look at the tracks of the field teams in 2024. As Matt Wallace says in this Instagram post, it only includes 190 out of the 218 eBird tracks of field teams, which accounts for some of the large gaps in coverage. But look at all the residential spaces in between the tracks! There are a lot of birds in those areas, and we’d like to count them. (If this doesn’t play on your device, try this link: Instagram.)

In addition, the field teams are all located within the Count Circle, which has a 24-km diameter. We want to cover that circle as fully as possible. But over the years the city has expanded beyond the boundaries of the circle, leaving many willing backyard observers outside the Count. We have started to include observations by Feeder Watchers who are in the city but outside of the circle as part of our Community Christmas Bird Count. Those observations cannot be counted in the official Audubon count, but we feel that it is important to do this to get a more complete picture of the winter birds in our city, and to involve as many people as possible.

Please fill out the registration form if you’d like to take part, either as a Feeder Watcher inside or outside the city, or as part of a field team.

Bonus Read: Below is a link to a recent article about the Inglewood Bird Sanctuary in the Calgary Journal which includes an interview with CBC organizer Matt Wallace.

Featuring a presentation on the wildlife of Southern Africa by Calvin van der Merwe

Next Thursday, November 13th, is our next Birds & Beers event in Calgary. We meet at the Legion at 9202 Horton Road SW, from 5 to 9 pm. Here is a message from Calvin van der Merwe, who will be presenting about the wildlife of Southern Africa:

Hello Calgary Birding Community. My name is Calvin van der Merwe, and my presentation is about birds and wildlife in Southern Africa. I grew up in Pretoria, studied in Cape Town, and have now found myself in the Alberta Wilderness. From the myriad of habitats in Northern Namibia, to the pans and rolling hills of the Kalahari Desert, to the endemics of the Cape and the forested and grassed extents of the Drakensberg escarpment, the tropical north-eastern coastline and it’s impressive wetland systems, to the Kruger National Park and the remote corners of Limpopo. If you enjoy incredible habitat, species diversity, exploration, and the array of other animals Southern Africa has to offer, this is the presentation for you. Here’s a Cape Parrot to whet the appetite.

The doors at the big ballroom will open for us at 5 pm. Come early to visit and have dinner and a drink. Or you can arrive any time before 7 pm when the presentation will begin. Everyone is welcome!

Note: There is no Birds & Beers meeting in December. We will resume in January.

2025 Calgary Christmas Bird Count

The 74th annual Calgary Christmas Bird Count (CBC YYC) will take place on Sunday, December 14, 2025. Here is a message from Coordinator Matt Wallace:

As you may know, Calgary hosts one of the largest CBCs in Alberta and Western Canada. In 2024, we had a total of 141 field participants and 163 feeder watchers, documenting 71 species and counting 39,446 individual birds. It’s a big job that takes an army of people to ensure its success each year. We hope you’ll join us again this season—no matter your experience or birding skills. Each one of you plays an important role, and the data we collect helps us understand long-term trends in our winter birds.

We’ve set up a Google Form that we kindly ask everyone to fill out so we have your most up-to-date information for analysis and team assignments. Please share the registration form widely with your network of neighbours, friends, family, and colleagues. Register Here. Once you submit your registration you will receive an acknowledgement email from us, followed by further instructions in mid-November.

A quick note: This year, I am seeking a “shadow” assistant (or assistants) to work with our organizing team. I plan to hand off the CBC Coordinator role to an inspired member of our community for the 2026 Calgary event, as I may be relocating in the new year. Finding a suitable successor will help ensure the continued success and legacy of this long-running event.

Birds Canada has also launched a pilot project encouraging CBC circles to have Community Engagement Leaders (CELs). Calgary has been ahead of the curve in this regard—this has essentially been my role in recent years, while Lara Fitzpatrick has handled much of the data analysis for our circle. Bob Lefebvre is another key member of our team, overseeing feeder watcher outreach and following up on notable or unusual bird reports.

Birds Canada: The CEL roles are defined as:

  • Participant recruitment and community outreach
  • Helping manage sector/section/zone assignments and coordination
  • Onboarding new participants and facilitating mentoring
  • Coordinating communications with participants

This pretty much sums up what we are looking for in the “Shadow Assistant” Role with this person leading the charge next year. If you’re interested in taking on the coordinator role, there’s an option on the registration form where you can indicate your interest and provide a few details. We’ll be in touch right away to include you in this year’s planning. We encourage anyone with an interest to apply!

Please watch for more information in November, including data submission instructions and templates.

A quick reminder that our CBC is open to anyone with an interest in the outdoors including experienced birders, novices, and the public. We try to accommodate all abilities and ages to grow and support our community, so please let us know if you need any assistance or have any requests using the comment section of the form.

Thank you very much for your attention—we’re looking forward to connecting with you all for our big count day!

No Costume Needed: Meet the Northern Shrike, the Bird of Halloween

Oct19

By Catherine Warwick

The most “Halloween” bird around is the Northern Shrike, aka, the “butcher bird”. Although it is a Passerine, which is a perching songbird, it has rejected the usual cutesy song-bird personality and instead is a merciless hunter. Not only does it hunt other birds, but it is known to rip its kill to shreds and impale pieces of the body on barb wire fences and tree branches. I don’t think a bird can get more grisly than that, it would even make a Crow shudder. It needs no costume to strike fear in a little bird’s heart, however it does sport a small black mask and a heavy hooked beak.

The Northern Shrike will scout out a nest or mouse hole and wait to strike. If it’s after a flying bird it may force it to the ground with its feet. Then it makes the kill with its hooked beak. In its upper bill (at the front) it has a vampirish toothlike spike, called a tomial tooth, that it uses to break the necks of its prey. 

The Shrike spends its summer in the far north and just comes to Calgary for the winter, that’s how tough it is. Apparently, it finds our “balmy” -20°C days pleasant.

Ron saw the pictured Northern Shrike at Carburn Park last winter.  Shrikes are known to return to the same winter territory year after year, so keep an eye out; you might see this tiny terror perched high atop a tree, scanning for its next victim.

In the summer they will head back to the far north to nest. One sweet fact about this bird – their nest is a deep cup that, when the female is in it, only her tail can be seen.

This winter get your binoculars ready to see a real horror icon: the Northern Shrike.

Note: The Northern Shrike has a summertime lookalike, the Loggerhead Shrike. Northern Shrikes are in our area from early October to late April. Loggerheads arrive in mid-May and can sometimes be seen into September. There is the possibility of a little overlap in May and September. Loggerhead Shrikes are a little smaller than Northerns, and have a clear breast without the barring of the Northern. They have a smaller bill with a tip that is less hooked, but they share the feeding habits of the Northern Shrike. -Bob

Featuring a presentation by Stephen Boucher called “The Roughly Right Guide to Botswana”

Next Thursday, October 9th, the Calgary Birds & Beers group will meet for our monthly social get-together and presentation. We are at the Legion at 9202 Horton Road SW in Calgary. We meet in the big ballroom, starting at 5 pm. Stephen’s presentation will begin at about 7 pm.

All photos by Stephen Boucher.

I am Stephen Boucher, retired from a long career in medicine and professional people watching as a psychiatrist.  In retirement I help with the Monday morning Friends of Fish Creek birding group and generally enjoy the outdoors and travel.

I have been asked to talk about my trip last year to Botswana. In retirement travel decisions lie at the nexus of interest, health, finances and at best, the opportunity to travel with great friends.

Botswana in September 2024 met all of the criteria. But why a Safari?

I grew up in the United Kingdom close to Chester Zoo and during my childhood, I remember clearly hearing the calls of the Sea-lions at 3pm feeding time and roar of the lions at dusk in the warm summer evenings. I have always enjoyed visiting Zoos. But the animals, though well cared for, are captive and some show abnormal repetitive behaviours.  It had been a lifelong dream to go on Safari and see the animals and birds of Africa in their wild habitat. In the era of Mass Tourism and “Selfie sticks”, I wondered if it was still possible to go on Safari and have a Robert Redford and Meryl Streep moment, like in the 1985 movie “Out of Africa”

The word Safari comes from the Arabic word “to journey”.  And along with my two Calgary friends Karen and Ed, plus John (a vet friend from the UK who is called “Mr. Safety”, by his hiking group) we had an amazing journey.

Tonight, I want you to sit back and come on Safari with me……

Everyone is welcome to join us at Birds & Beers. The cost is about a dollar per person to cover the charge for the room. See you there!

Ghosted By A Sora

By Catherine Warwick

One of the birds leaving Calgary this September is the Sora. Were you one of the lucky few who saw it at the North Glenmore storm pond?

A few years ago I saw one of these charismatic birds at Inglewood, I was with my sister who is not really a birder. The conversation went like this:

(a Sora just casually standing in a pond in full view)

Me: Holy Cow! A Sora! Wow I can’t believe it, look at it! Wow! We are so lucky, how rare!

Sister: That’s nice.

Me: We are so lucky! This is amazing!

Sister: Uh huh (starts walking).

And yet if she became a birder and started looking for a Sora it would probably take years to see one. I trolled that North Glenmore Storm pond so many times this summer and nothing! The Sora is one of those birds only birders know about. Even though they are common they are really good at hiding in the reeds.

Sora

The Sora is a plump little chicken-like bird that belongs to the Rail family. They frequent ponds and wetlands. The Sora has very long toes that help them walk on floating mats of vegetation. They are grey and brown with an impossibly yellow triangle beak. The first time I saw one at the storm pond I thought it was floating because it was standing in water that came up to its undercarriage. I was flipping through my Sibleys looking for a duck with a yellow triangle beak. The most obvious identifier is their call, a descending laughing sound. Although lately I feel like the Red Winged Blackbirds around the storm pond are mimicking it which has caused me a lot of disappointment. Birding – what a roller coaster!

When a Sora walks it puts its head forward with each step as it looks for aquatic plant seeds or bugs to eat. It’s been known to use its long toes to rake the vegetation. Their long legs are great for running away really quickly, often you will just get a glimpse of them. A brown blur with a yellow streak.

Now that it’s September our little storm pond Sora will be departing on a very long journey, possibly as far as South America. They fly further than any other Rail despite their circular form and long legs. Hopefully it is back next year and I can have another season of attempting to spot the beguiling Sora.

Birds & Beers Returns September 11, 2025!

With a Presentation on “Birding in Belize” by Daniel Arndt.

The fall season of Birds & Beers begins next Thursday, September 11th. As usual, we meet from 5-9 pm in the ballroom at the Royal Canadian Legion at 9202 Horton Road SW. Everyone is welcome!

Come early if you can, but be sure to be there by 7 pm, when Dan Arndt will present “Birding in Belize: An Introduction to Birding the Tropics.”

Ocellated Turkey

Dan has travelled Belize extensively, and visited some of the best birding locations the country has to offer. In March 2026, Dan will be leading a tour to Belize along with local guide, Roni Martinez, to La Milpa Biological Station, Blue Creek, Mountain Pine Ridge, Caracol, Chiquibul Forest Reserve, La Milpa Archaeological Site, and Crooked Tree Lagoon. Some of the most sought after birds in Belize include Ornate Hawk-Eagle, Ocellated Turkey,  King Vulture, Jabiru Stork, and Agami Heron. 

Belize is an excellent introductory tour for folks new to birding the tropics, with many familiar species that breed in North America on full display and preparing for their northern migration, and travel throughout the relatively small country allows for quick access to a variety of habitats. The archaeological history of the Mayan people, and the great birding found at these archaeological sites is a unique blend of human history and ecological conservation that is rarely found elsewhere in the world.

Here is a link to Dan’s 2026 Belize Birding Tour on the Meadowlark Birding Tours website.

This will be a great start to the Birds & Beers season. Upcoming meeting dates are Thursday October 9, and Thursday November 13 (all are on the second Thursday of the month). We take the month of December off, and then resume again in January.

One change this year is that we are being charged a little more for the use of the room. (It is still very reasonable at $100.) So we will again ask that people make a small donation, if they wish, to help cover this. We usually get anywhere from 50 to 100 attendees, so if you give a dollar or two, that will be plenty. Paying is optional, though, so please don’t feel you have to contribute! Attendees have been very generous with this, and we have always received more than was needed to cover the room cost, and we just donated the extra money to the Legion. We will continue to do this.

See you there!
