Avian Pox

Posted by Bob Lefebvre

I feed birds in my SE Calgary yard and spend a lot of time watching them. Recently I saw something new – a bird with some really obvious large growths on it.

I wasn’t sure what this was at first but a quick internet search identified the problem as avian pox. This is a virus that comes in two forms, one of which causes these dry wart-like growths on the parts of the bird without feathers (feet, legs, base of the bill, and around the eyes). The other form affects the respiratory and gastrointestinal tracts. It’s a problem, and something to watch out for at your own feeders.

Avian pox is highly contagious and is transmitted by mosquitos, but birds can also become infected by by direct contact with infected birds. Birds can also get the virus indirectly through contaminated feeders or birdbaths, or even dust from the ground below these. Fortunately, the virus cannot infect humans or pets like cats and dogs (but is very dangerous to captive or farmed birds).

So what to do? This particular bird has obviously been infected for quite a while, and it can still feed, so it appears to be otherwise healthy. Such birds can survive the virus and the growths may drop off in time. The first thing to do to prevent spread of the disease is to immediately remove the bird feeders and birdbaths, which may be contaminated, and to clean them thoroughly in a 10% bleach solution. I had one heated birdbath and four metal tubes with tree nuts which I removed and disinfected (I also disposed of the remaining nuts in the feeders). I did not have a sunflower feeder up at the time. In the winter I spread sunflower seeds on ground which I have cleared of snow. The many Dark-eyed Juncos and our pair of Eurasian Collared-Doves prefer to feed this way. House Finches and House Sparrows, Eastern Gray Squirrels, and Magpies also feed on the ground. The tube nut feeders are used mostly by at least eight Northern Flickers who come daily, but are also frequented by a pair of Downy Woodpeckers, a few Red-breasted Nuthatches, and occasionally by Black-capped Chickadees. If no easy food is available on the ground, House Sparrows and Magpies willl do their best at the tube feeders, but get very little.

I put the feeders and birdbath away and stopped putting out sunflower seed too. Disinfecting the birdbath and feeders keeps them safe for about two weeks, but I wanted to make sure the bird wasn’t still around. Since I hadn’t seen it before, I thought it might be a one-time visit. After ten days I put the tube feeders and birdbath back out, but still did not feed the ground birds since that attracts magpies (and the ground could still be contaminated). A few days later, I saw the infected bird briefly, on the ground once again, so I removed the birdbath and disinfected it again. I continued to use the nut feeders, since I hadn’t seen this magpie, or any magpie, feed on there this winter. I saw the infected bird a third time in late March but not since.

I hope I don’t see the infected bird in my yard again but of course it may be visiting other feeders in the area and possibly spreading the infection. I had been advised by the Calgary Wildlife Rehabilitation Society that I should try to capture the bird and take it to them, to remove it from the population while it heals. I could do this – I have a small animal trap that I’ve used for feral cats, and I have occasionally caught magpies while doing that. But the infected magpie rarely shows up, and meanwhile I would likely capture the regular local magpies, cats, and other birds if I put a baited trap out. For now I’ll wait to see if it returns.

To try to get an idea of how common this disease is in Calgary, I contacted The Wild Bird Store to see if they had heard of any cases of Avian Pox from their customers. They had not heard of any at all. On iNaturalist, there is only one other case reported in Calgary, a magpie that was badly infected in the NW last fall. You can see the photos of that bird here. (It doesn’t look like the same bird I saw and was miles away from my location.) So avian pox seems to be very rare in the city.

Please note that it is important to always disinfect your feeders and birdbath at least monthly, to prevent the spread of not just avian pox, but other diseases as well. A common one is conjunctivitius in House Finches, which I have seen in a bird in my yard as well (a few years ago).

More information about avian pox is here: Cornell University Wildlife Health Lab.

Birds & Beers, April 9, 2026

With a presentation on Antarctica by Karen Keller

On Thursday April 9th we will meet again at the Legion at 9202 Horton Rd SW in Calgary for our monthly Birds & Beers social get-together. These informal meetings are open to everyone, and provide a venue to meet with your fellow birders and enjoy food, drink, and an interesting presentation about birds. The doors open at 5 pm, and the presentation begins at 7 pm.

This month features a talk that is not only about birds, but is also a fascinating travel adventure and a look at some amazing history as well. Karen Keller will present A Journey Into the Antarctica, November 2023.

Karen writes:

We will be sailing from Ushuaia, the bottom of the world, Argentina, to the Falkland
Islands. We will then sail to South Georgia Island, the Serengeti of the Antarctica, visiting sites
with abundant wildlife and birds, including Penguins. We will follow Shackleton and stop at the almost-never-visited sites that Ernest Shackleton landed on, on South Georgia Island. Ernest Shackleton’s amazing journey of survival and loyalty to his men, is one of the most exciting and inspiring stories that you will ever hear.

About Karen Keller:

Karen Keller
Karen Keller.

Karen grew up in Winnipeg and was always out with her Dad at the local marshes and
countryside, to see the birds and wildlife. Her interest with photography started in 1960, using the little Brownie camera. In 1977, Karen acquired the Canon AE-1 and took photography courses. The two hobbies would become her passion throughout her life.

Karen’s obsession with birds made her want to fly like a bird. In 1978, she took hang gliding lessons, and flew for 25 years, becoming an instructor as she slowed down. The reason, we moved to Calgary, near the mountains, in 1979.

Karen’s love for nature and photography keeps her passionate, happy, and excited.

Everyone is welcome to join us at Birds & Beers, including children if accompanied by an adult. There is a small fee to pay for the room, so we ask for an optional donation of $1 per person. Any extra money beyond the room cost is donated to the Legion. See you there!

Birds & Beers meetings are held monthly at the same time and location, on the second Thursday of each month, except July, August, and December. Upcoming on Thursday May 14 – John & Maria Kimber, The Galapagos Islands. And don’t forget about a special event on Saturday May 16 – The Book Launch of A Field Guide to the Birds of Alberta by Gavin McKinnon and David Scott.

Welcome Back, Swamp Boss: The Red-winged Blackbird Returns

By Cathy Warwick

Guess who is coming back to Calgary this spring, the Red-winged Blackbird! This feels like a spring where Mother Nature will roll out the “white carpet” for these hardy birds. Hopefully they won’t turn right around and head back south.

Red-winged Blackbird
Courtship Display, Red-Winged Blackbird. Wikipedia.

For birders the Red-winged Blackbird is, thankfully, relatively easy to spot. They are widespread and, as birding books like Sibley’s call them, “conspicuous”, that means they make themselves seen. The males are glossy black with a military-esque red and yellow striped patch on their shoulders. The females are much harder to identify, and are almost sparrow-like, although larger. If you have ever seen a female out of context, as I have on a conifer tree, you will know what I mean.

Red-winged Blackbird

One of the main attributes of these birds is that they are highly territorial, befitting their military regalia. Their distinctive tumbling song can be translated to “Stay out of this swampy area, it’s mine!” repeated endlessly, all day. This is the male of course, chasing other Red-winged Blackbirds out and any other perceived threats to nests, including humans sometimes. His song is also for the benefit of the females, he will show off his red shoulders and puff up a bit and then sing loudly – ”conk-la-reeee”. 

Red-winged Blackbird

Meanwhile the females are quietly building the nests in the territory. They lash their sweet cup nests to reeds or tall grasses. As a finishing touch they line the nest with fine grasses. A male can have many female mates, although it turns out the eggs in his territory are not always his. The little swampy area has more drama than a Mexican soap opera.

If you want an (almost) guaranteed sighting of a Red-winged Blackbird head to Ralph Klein Park. This is a 30 acre wetland area in the eastern part of the city that could, frankly, use more visitors. The last time I was there it seemed to be just me and my son. These parks need more appreciation, to encourage more parks and more preserved wetlands. An unwilling teenager and his mom are not going to cut it.

In between all the Red-winged Blackbirds you will see a lot of other wetland species. Last time we were lucky enough to see a Black-crowned Night Heron. They also have a great interpretive center, similar to the Inglewood Bird Sanctuary.

Welcome back Red-winged Blackbird! I can’t wait to hear your song, although I can’t guarantee I will stay out of your territory.

Consider the Bald Eagle a good luck symbol – unless you’re a Gull

By Cathy Warwick

When I do an internet search on a Bald Eagle I can see what other popular searches come up. As with other birds, there is one that says ‘what does it mean when I see a Bald Eagle’. Before I started writing articles I wasn’t aware that people looked at birds as little omens as they went about their day.

The most dramatic behaviour of a Bald Eagle I have seen is when I was swimming in the Pacific Ocean one year. An eagle swooped down and snatched a gull who was casually paddling near me. I know for that poor gull, whose last look at earth included a fast receding woman in the ocean, mouth agape, the eagle was a very bad omen.

Bald Eagle

These impressive creatures can be seen near bodies of water around our city. Carburn Park, Inglewood Bird Sanctuary, Sandy Beach, the Bow River, Glenmore Dam and sometimes just flying over your neighbourhood. They are about 2-3 feet in height (almost 1 metre) and can have a wingspan of almost 7 feet (2 metres) – a huge bird! They build mega nests, at least 6 feet wide, way at the top of trees. As they will reuse them yearly and keep building them out, it’s a wonder they don’t add a front door and chimney. 

Most people recognize them by their two-color uniform of a white head and a brown body. Of course they are not actually bald, the word ‘bald’ means ‘white’ in ye olde English. It’s wise to remember that immature Bald Eagles can be completely brown and as big as a mature Bald Eagle. Don’t go assuming you are seeing a Golden Eagle! There have been too many “Golden Eagle” sightings in Calgary, I wouldn’t be marking that in eBird unless the bird flew close enough to let me see its legs that are feathered to the toes. If it did a kick dance in front of me and I saw its “feathered boots” clearly, then maybe I would mark it as a Golden Eagle. Another way to tell is that while the Bald Eagle flies with its wings straight out like a board, the Golden will hold them in a slight “V”.

Bald Eagles like fish, but definitely aren’t picky, and, like most of us, will eat whatever is easiest. Often that means carrion or stealing another predator’s food. They can fill up on food when it’s available and then have nothing for many days. 

Bald Eagle

Their impressive size, huge talons and fierce looks lend them to becoming a powerful symbol. The United States adopted them as such of course. Perhaps that government’s ties to the Bald Eagle hastened the banning of DDT, which severely impacted the eagles’ numbers in the early and mid 1900s. If so, we are lucky that the Bald Eagle is around to act as an ‘Umbrella Species’ to the many other birds and animals that were also protected by the banning of DDT.  Humans often need a symbol to focus their efforts on. The Bald Eagle was an Endangered Species for a while there, thankfully they are off that list as of 2017. Many of the Indigenous Peoples of North America viewed this eagle as a spiritual symbol, or a messenger from the spirit world. 

The Bald Eagle Wikipedia page is so long compared to other birds!

If you are walking around Calgary and you see a Bald Eagle you really can consider it a lucky omen, considering you were lucky enough to see it.

Winter Birding Homestretch!!

February 28th is the last day to add to our winter bird list (and yours).

Posted by Bob Lefebvre

Although we have had some snow and cold weather in the Calgary area recently, this has been a very mild winter for the most part. One might assume that more bird species than usual would be found, since more birders are spending more time outside, and the mild conditons would allow for more overwintering birds. But the factors that lead to birds wintering farther north than usual are complex, and this winter has seen slightly fewer species here than normal. We may still get a few late ones.

As of February 24th 2026, we have 109 species in the 80-km radius Calgary Circle. The average over the previous eight years was 113, with a low of 108 and a high of 120.

Part of the reason for the low number is that a few fairly regular species have not been found. Some of these are ones that usually overwinter in small numbers and are often found near the begining of the count period, in the first couple of weeks of December. This includes Yellow-rumped Warbler (seen in 5 of the previous 8 winters), Western Meadowlark (4/8), and Rusty Blackbird (7/8). We did get a Red-winged Blackbird recently, which makes it 8/9 years that we’ve had one. There are quite a few in the southernmost part of the province this winter.

Varied Thrush

One species that usually overwinters in small numbers and could still be found is the Varied Thrush. We had at least one for seven straight years from 2017 until two winters ago, missed last year, and have not had one yet this winter. There could still be some around, and they can be seen at feeders in the winter, feeding on the ground.

Some birds are almost certainly around and we usually get them, but are very hard to find. There are species that are probably present in low numbers like Steller’s Jay, which is alway found in the Bow River corridor near Canmore, and 6/8 years here, usually at the western edge of our circle. Other species may be here but in hard-to-access places, like White-tailed Ptarmigan, which we have only had once, but Bow Valley has had every year.

Steller's Jay
Steller’s Jays will come to feeders, like this one in Bragg Creek in 2012. Photo by Dan Arndt.

Boreal Owls are certainly present in the area, but are very hard to find. We have only had them in 3/8 years, and not yet this wiinter. We are also missing Northern Hawk Owl, which comes south in good numbers some years, but is very scarce this year. We have had this species every previous winter.

The only new species for the count this year is Glaucous Gull. A few were seen in the area (and in the Bow Valley!) in January. The Northern Mockingbird that was here until the first week of January was the second one on our list. The Spotted Towhee that has been in Redwood Meadows all winter is also just the second record.

There are some recent additions to this year’s list, including Black-backed Woodpecker in west Bragg Creek on February 9th. This is another hard-to-find species that is always here, and we now have it in all 9 years. A Spruce Grouse (now 9/9 years) was seen on Grand Valley Road on February 9th. This is one that is always present but only on the western edge where it can be hard to find. A Greater White-fronted Goose (6/9 years) was found at the 68 Street Wetlands on February 16th. Maybe it was hidden all winter among the thousands of Canada Geese we have. Finally, we got a Gray-crowned Rosy-Finch (7/9) near Millarville on February 16th. This species can be present in large or small numbers, or entirley absent from the area. It is usually near the western edge.

There are a few species not on our list which have had unconfirmed reports. These are ones that are unlikely to be here and could have been confused with other species. If there are no photos these are usually not accepted by eBird, nor by our list-keepers.

Finally, are there any returning migrants that we could expect in the next four days that are not already on the list? It seems unlikely. The best bet every year is California Gull. They usually arrive in the first week of March, followed closely by the Ring-billed Gulls. Currently, there are only a very small number of Californias in central Montana. There are more in the Kallispell region, along with quite a few Ring-bills, but those birds may go straight north into British Columbia. We have only had Californias arrive by the end of February once, in 2020, and it was on leap day, Febraury 29th. I recall standing in my back yard at dusk that night when a single California Gull flew over. Going farther back, Californias arrived on February 26 in 2016 (before we started the winter list). We haven’t had Ring-bills in February. The most likely place to get a gull in late February is probably the 68 Street Wetlands east of Elliston Park. Maybe you’ll see me standing there at dusk on Saturday!

The Bohemian Waxwing – A Social Showstopper

By Cathy Warwick

Bohemian Waxwing

There is a large flock of Bohemian Waxwing flying around the North Glenmore Park, it’s great to see them back! These social birds are usually found in a tight flock that is full of non-stop trilling and fluttering. Their flocks can number in the thousands, however the one I saw looked to be about 150 birds. The best way to guarantee the number of birds is to be the only one around to count them. In this case I didn’t have much time because a car honked and they took off in a moving cloud, trilling away.

Bohemain Waxwing
Bohemian Waxwings are primarily fruit-eaters in the winter, and in Calgary they usually eat Mountain Ash berries. Wikimedia commons, no restrictions, Lisa Hupp/USFWS.

I have a soft spot for masked birds, so the Bohemian and Cedar Waxwings are always a welcome sight. These two birds are very similar to one another. However looking at their bar chart on eBird for Calgary it’s like they have two shifts, a Winter shift and a Summer shift. That makes it easy to guess which species you are looking at. The Bohemian Waxwing summers in the north, they must feel right at home in the cold, so they took the winter shift. You can also see from this chart that a few hardy (and perhaps not very bright) Cedar Waxwings stick it out here in Calgary over the winter.

Bohemain Waxwing
Cedar Waxwing

How to tell if a stray Cedar is in a flock of Bohemians? The Bohemian Waxwing can be identified by its Cinnamon undertail and they are plumper and more jolly looking, than their sleeker cousin. Both birds have the sweet black mask and funky head plumage, as well as bright colors at the end of their wingtips and tails. This is where they get their name from, previous generations thought their wingtips looked like they had been dipped in wax. This is another example of how much day-to-day life has changed, the importance of wax has plummeted in the modern era.

Bohemain Waxwing

The trilling sound they make is not a true song but a high-pitched sound that is nevertheless very distinct. I’m sure they are discussing something of great importance, probably where the dried berries are, which is their winter food. The abundance of Mountain Ash in Calgary would make you think they have it made here, however their populations see wild fluctuations. For example in the below chart we have the eBird total sightings for the winter months in Calgary. The numbers have dropped drastically, especially in 2025. As their name suggests they are wanderers at heart so we can only hope there is a berry laden place somewhere else in Alberta where they are all congregating. 

Total birds on eBird checklists, Winter months. 5 year comparison:

Bohemain Waxwing

Even if there is some other factor, like a Bohemian Waxwing loving birder has moved from Calgary, the numbers are telling us these birds aren’t around as much. In fact, although these birds are considered ‘common’, the “Partners in Flight” organization has identified them as a “Species in Steep Decline”. This organization is made up of a network of more than 150 partner organizations in the Western Hemisphere, concerned with landbirds specifically.

If you see the Bohemian Waxwings in North Glenmore, take a moment to admire them, I know I did until the horn honked, a clear warning in the cold winter air.

Calgary Christmas Bird Count Results

68 species, 43,631 birds counted on December 14th, 2025.

Results will be publicly presented on February 26, 2026.

Posted by Bob Lefebvre

We had another very successful Christmas Bird Count (CBC) in Calgary on Sunday December 14th. The sixty-eight species found inside the Count Circle was one more than our average over the past fifteen years. We had 265 people take part in the count, with 154 out in the field, and 111 Feeder Watchers counting birds from their homes.

Another way to see some of the results is to view our eBird Trip Report, which includes most of the checklists from our Field Teams, and has photos of dozens of the species reported.

Presenting the Results

On Thursday February 26th we will be having a special meeting at the Royal Canadian Legion, 9202 Horton Road SW to present the results of the Calgary CBC. (This is the same location where the Birds & Beers meetings are held.) In addition to the Calgary CBC, we will have a presentation on the Fish Creek Park New Year’s Day Count, and we are working on getting some more presenters for some of the other southern-Alberta CBC’s. Save the date, and I will be posting more details about this event in mid-February. Join us for more information and many more photos from the Count!
