Moulting Is Not Revolting

By Cathy Warwick

No! Of course moulting is not revolting, it is a natural part in the seasonal cycle of being a duck. No need to be embarrassed and hide away. Wait a second, maybe there is a need, since they can’t fly anymore to get away from predators!

Did you know many ducks moult once a year, in late summer or early fall? This means they shed most of their primary feathers all at once to grow new ones. The process can take about 20-30 days and during that period they lay low since they become flightless. If you have ever seen a pile of feathers and thought a coyote had lunch, it may not be so. The duck feathers can come off quickly and dramatically.

Not only do they become flightless, they become difficult to identify. Their beautiful and colourful plumage becomes a beige-gray bore before moulting begins. Typically this is in the summer months. This outfit is called their ‘eclipse plumage’ and it isn’t a favourite of birders. The term eclipse refers to the boring plumage darkening their usual colours. If you do an internet search for any type of waterfowl the pictures will show them in their breeding plumage, striking and unmistakable. Meanwhile you are peering through the binoculars at a beige lump wondering why birding is so difficult. We’ve all been there. At that point you can start looking for eye rings and tail shapes, which gets challenging. Or you also have the option of saying ‘oh a duck’ and watching them paddle around a bit.

I was surprised to learn that the Blue Jay moults all its head feathers at once. I have never seen that out in the wild and I suspect it’s because they hide away during this phase. It is such a radical difference from their usual spiky crown, They look like a tiny vulture with bugged out eyes. It only lasts for a week but you get the feeling if any bird were vain, it would be the Blue Jay. It’s amazing how much shape and bulk the feathers give birds, look at the difference between the two pictures of the Blue Jay, it’s hard to believe it’s even the same bird.

The larger birds and waterfowl are more inconvenienced by their moult season than smaller birds. Their feathers take longer to grow in. They often moult right before migration to have a nice strong set of new feathers to take them south. I imagine they are in the air now with their new outfits, ready to party in Mexico.

A Fiesty Hummingbird

Sep22

By Cathy Warwick

The Rufous Hummingbird is one of several hummingbirds that visit Calgary, and certainly the most feisty. They are very territorial and are known to chase away other hummingbirds from feeders, and have also been seen chasing squirrels and chipmunks. Although the idea that such a cute, eight centimeter bird can be frightening is comical, their shocking speed and poky looking beak would have me running for cover!

This summer I had the good luck to watch a Rufous Hummingbird for a solid ten minutes. I watched it stretch its tail feathers and stick its tongue out while it was perched on a branch. Prior to that I had been chasing after it as it flitted around, finally I just decided to sit down and see if it would show itself, a wise decision as they can go about 45 km/hr. I managed to look at it while it took a break from its endless battle with another Rufous Hummingbird. I saw that it had some green on it, as well as the rufous red, it was a female or immature male. The fully grown male is a nice coppery colour all over with a shimmery chin. Hummingbirds are hard to identify, firstly they are so fast you are lucky to see any markings and secondly they often have a range of plumage that is shared with other hummers. I used the Merlin app to be sure.

These tough little birds travel up to 3000 miles during migration. All the way from Southern Mexico to Alaska, so far for a tiny bird, maybe it can just soar on the winds. It doesn’t seem to be the type to let the wind do all the work though, the one I saw was constantly beating its wings while flying. According to All About Birds they fly up through California, then Washington and BC. After that they go east and fly down the Rockies, completing a clockwise circle. So for Calgary they will come through on their way south especially during August.

To attract a Rufous Hummingbird to your yard consider planting Honeysuckle, like my sister-in-law who saw them frequently this summer. They will take a while to find it but once they do they will come back yearly. The Atlas of Breeding Birds of British Columbia mentions that they will band Rufous and note the same bird at the same feeder on the same day, year after year! Our Honeysuckle died over the winter and we had a Hummingbird on our deck looking in the back window, as if it wanted to complain to the manager.

A Hummingbird feeder is also an option. There are a lot of resources on the internet that explain how to set one up and what to use as a solution. I’ll just mention that you need to change the solution at regular intervals to provide optimum fuel for them. A Hummingbird is a finely tuned organism whose heart beats 1,260 times per minute, vs. a human’s 80ish beats. Perhaps consider putting out multiple small feeders so the Rufous lets other hummingbirds also feed.

I hope you had a chance to see this small bird with an outsize personality this summer!

Rufous Hummingbirds can been seen on their breeding grounds in Calgary in the Weaselhead Nature Area, Griffits Wood Park, and other parts of the west end of the city. They arrive here on about May 10 and can be seen until September.

Osprey in the City

Jun1

By Cathy Warwick

Our sports fans are back in town. There is a pair of Osprey in Calgary’s southwest that have a nest overlooking an athletic centre and parking lot. The hustle and bustle of sports surrounds them and they appear to be used to it. I went and checked them out on a spring morning and watched one eat some fish while perched on top of a pole. As I watched the big bird with my binoculars surveying her territory, she was probably counting the breakfast crumbs on my sweater, her eyesight is that good.

The Osprey is also called a fish hawk because of its strict diet of fish. The pair of Osprey I visited fly over to Sandy Beach and patrol the river. For every hunting trip an Osprey makes it is estimated that they are successful 70% of the time. According to Cornell, the Osprey spends an average of only twelve minutes hunting per trip! Human anglers should take note of their tactics.

They spot a fish and then dive in with their sharp talons, which have a ‘opposable thumb’ type of claw at the back. Their talons also have scales going in a direction that snags the fish onto them. This feature, coupled with their strong grip, means they can be dragged under the water by a larger fish, if they get too greedy. They have also been known to dive under the water to get a fish, then to get out they ‘swim’ with their wings. These skills, coupled with their amazing vision, make them fishing machines. It’s enough to make the average angler throw their little pole and string in the bushes and march off in disgust.

Ospreys are often used to illustrate the effects DDT and PCBs had on our ecosystems, since they are the pinnacle of their food chain. Being at the top, they end up absorbing all the bad stuff in our waterways and DDT causes their eggs to have thin shells. This had catastrophic effects back in the 70’s – Ospreys were actually endangered in some areas. It’s heartening to see how they have rebounded and now have a status of ‘Least Concern’. Ospreys are all over the world, on every continent except Antarctica, and who would want to live there and hang out with a bunch of silly penguins.

During nest building the male Osprey usually gathers the materials and the female arranges it to make a nest. Last year the male had brought his mate a pair of black athletic shorts and they were acting more as a flag, hanging from the bottom. Perhaps from their favourite team? This year it looks like they are making use of a rope and an unidentified piece of cloth. I couldn’t really tell, with all the sticks and extras making up its nest, but it looked like there was no actual nesting platform for this pair. It brings up the question of why the Osprey don’t like the very sturdy nest platforms in Weaslehead. I have never seen an Osprey nest on those ones in all the years they have been there. Perhaps it is about the fishing opportunities down there? Maybe we need to organize some sporting events for them to watch?

Below are some photos of Osprey from another well-known nesting site in the city – the art sculpture on St. Patrick’s Island by the zoo downtown. The photos were taken by Onkar Kadim in summer 2023.

The Birds Of Alberta Podcast

May15

Chris Fisher’s new podcast is entertaining and informative.

Posted by Bob Lefebvre

I listen to a lot of podcasts, and recently I stumbled upon a new one from the Alberta naturalist Chris Fisher. Chris is probably best-known as the co-author (with John Acorn) of the excellent Birds Of Alberta field guide. The new podcast, also called Birds of Alberta, began on March 28, and there have been sixteen episodes so far. Each one focuses on a single wildlife species that can be found in Alberta. This is usually a bird, but there was also a really good episode about Wood Frogs.

Each episode is fairly short, ranging from eleven minutes to twenty-two minutes. As the description above says, they are about “the special experiences that the birds have while in this province to the special experiences that Albertans have with their birds”. It is not an interview format, but just Chris sharing his wide knowledge of Alberta wildlife.

I really enjoyed all the episodes so far, and I’m looking forward to more.

Check out the Birds of Alberta podcast – it is a welcome addition to Alberta’s wildlife media.

Great Horned Owlets

Happy Mother’s Day from Birds Calgary!

Posted by Bob Lefebvre

A pair of Great Horned Owls have nested on Ramona Casault’s acreage west of Calgary for several years. Ramona calls the adults Winnie and Waldo. There are three chicks this year, the last of which hatched just last week.

According to Ramona, both parent owls have taken turns brooding the chicks, and now sometimes will both be outside the nest tree and leave the chicks for a while.

Cuteness overload! Happy Mother’s Day!

City Nature Challenge 2024

Apr7

Thursday April 26 through Monday April 29

Posted by Bob Lefebvre

The sixth annual Calgary City Nature Challenge is coming up soon. This four-day bioblitz is an effort to try to record as much of the Calgary and area biodiversity as possible. Cities around the world will be taking part in this effort, and competing to see who makes the most observations and records the most species. As usual, Calgary will be competing to try to increase our own participation and species numbers here.

From CNC Organizer Matthew Wallace:

The sixth annual Calgary City Nature Challenge takes place April 26-29! Over 650 cities worldwide will compete and collaborate to showcase their urban biodiversity! Participate by taking photos of wild plants and animals in your yards, neighborhoods, and favorite parks over the four days. Then, upload your observations to the iNaturalist app or iNaturalist.ca!

There are several public events happening across the city which include pollinator walks, guided birding tours, and park bioblitzes. You can also just head out to explore on your own or with a group of friends.

Participate anywhere within the Calgary Metropolitan Region which includes Calgary, Airdrie, Chestermere, Okotoks, Rocky View County, and Foothills County.

The deadline to upload your observations to iNaturalist is midnight May 5.

Cities will compete to see which can make the most observations, document the most species, and engage the most people. Calgary aims to be the top-performing Canadian city with a goal of over 10,000 observations posted. Make as many observations as you can April 26-29 so get outside and help to put Calgary’s biodiversity on the map!

Check out all of the CNC resources on the following pages:

The City Nature Challenge webpage. Watch the events tab as more field trips are added.

CNC 2024 Facebook Page

The Project Page on the iNaturalist website.

As birders, we can participate by taking as many photos of birds as we can over the four days. Any identifiable photo is good so don’t worry too much about the quality of your pictures. We also need to document everything, so don’t hesitate to photograph House Sparrows, Black-billed Magpies, and other common species. Then you have until midnight on May 5 to upload your photos to iNaturalist.

These were a few of the other species I saw on the 2023 CNC. I didn’t know some of the species identifications until I entered them into iNaturalist. (Photos by Bob Lefebvre.)

Since I have my phone with me when I’m birding, I can use it to get photos of other species which are difficult to get with a big camera (photos by Bob Lefebvre):

Brickwork Woodlouse — Elegant Sunburst Lichen

I have found it to be a great experience to use iNaturalist to learn more about our overall biodiversity. Like most birders, I am interested in all of nature, not just birds.

Watch this short video about the 2024 Calgary City Nature Challenge:

Matthew has set a goal of having 10,000 observations made over the four days this year. In 2023 we had 9,301, so we are getting closer! We also hope to better our total of 762 species recorded last year.

So check out the project links above and plan to participate in an event, or just head out on your own!

Welcome Back Mountain Bluebirds!

Apr4

By Cathy Warwick

The Mountain Bluebirds are back in Calgary and surrounding areas! The “Friends of Fish Creek” birders saw five at Carburn Park on March 21st. The Bluebirds appear to arrive faithfully on the Spring Equinox every year. This picture Carole Steeves took of a Mountain Bluebird sort of sums it up. Imagine you fly all night from the Southern States and, exhausted, you land in Calgary only to be greeted by a cold wind and snow covering all the food. Perhaps I am projecting my own “snow-fatigue” onto this bird in the picture. Hang in there little guy, things will turn around soon. And then it will get bad again, and then better again… this is Calgary after all.

This cold Bluebird is probably stuck eating seeds and old berries it finds. When the weather gets warmer it will switch to its main food source – insects. According to Audobon.com, it especially likes caterpillars, beetles and grasshoppers. Maybe that’s why it makes its home in the open fields around Southern Alberta, a lot of bugs.

Years ago my family traveled up to the Ellis Bird Farm near Lacombe expecting to see a flock of Mountain Bluebirds in the spring. It was there that I learned that the bluebirds are very territorial while breeding and, according to their fact sheet, need to nest about 2-3 acres apart. That is why the nest boxes are put on what is called a ‘Mountain Bluebird Trail’. There are many such trails in Alberta and the efforts of volunteers building and monitoring nesting boxes can be read about all over the internet. It’s fun to slowly drive down a Bluebird trail. If you’re lucky you will see the unmistakable bright blue of a Male Mountain Bluebird. They are like a piece of the summer sky come to life. If you see a bird pop out of the nest that is more navy blue with a bright white chest then is probably a Tree Swallow that has taken a nest box.

Like the Blue Jay the blue comes from the structure of the feathers and the way it refracts the light. There is no actual blue pigment in the Mountain Bluebirds feathers. This is probably one of the more irritating facts that you can tell a beginner birder – “That bird isn’t really blue you know.” Birders already have a nerdy reputation so let’s use this fact sparingly. It’s interesting though, this bird really is sky blue, as the sky is also just refracted blue wavelengths.

The Mountain Bluebirds are in a hot competition for nesting cavities. They fight Tree Swallows, House Sparrows, other Mountain Bluebirds and worst of all – the European Starling. Yes, these aren’t your blue birds of song, flitting around Cinderella and landing on available shoulders. Reading about them on the internet the adjective “aggressive” comes up a lot. The Mountain Bluebirds are tough fighters scraping out a living. Needless to say, their population numbers fluctuate and although they are currently listed as ‘Least Concern’ their peak in population was in the 1940’s. According to the Nature Conservancy of Canada they have decreased by approximately 26 per cent between 1966 and 2014. Their scrappy, fighting spirit will be needed, as well as the help from the nest box volunteers.

Here is a link to the Calgary Area NestBox Monitors Society

Note: In addition to a number of migrating Mountain Bluebirds that have been seen along the Bow River in the past two weeks, there was a pair of Western Bluebirds seen at Carburn Park up until March 30. This species is rarely seen in Alberta, and this is likely the first sighting ever in the city.

2024 marks the 25^th anniversary of the Brooks count –- come celebrate this milestone with us! To register, click here: Brooks and Writing-on-Stone 2024 registration form. Registration will close on April 30, 2024.

We will hold pre-count meetings on the Fridays before each weekend. At these meetings we will assign count areas, distribute maps and checklists, go over count protocols, introduce your fellow birders, and answer questions. Please plan to be there. We will also host informal gatherings on the Saturday evenings – a great opportunity to get together to swap birding stories and win some fun prizes! A full schedule for both weekends can be found in the brochure below.

Because weather is sometimes inclement on the Brooks weekend, we have reserved a meeting space at the Heritage inn (note new location). We are asking each participant in the Brooks count to contribute $12.00 to cover meeting room costs. If you plan to join the Brooks count, please e-transfer $12.00 per person to Donna Wieckowski astolat@shaw.ca no later than May 15. Cheques and cash also accepted. Thanks!

Results of the January 1, 2024 Fish Creek Park Count.

Posted by Bob Lefebvre

The annual half-day bird count in Fish Creek Park was a lot of fun and a great success again this New Year’s Day. We had a high number of species, with high counts for several, and some new species for the count. It was another mild day, as it had been for pretty much the whole winter up to then.

Despite the Park Rules, someone has been leaving seeds for the birds. This Downy Woodpecker was so used to being fed that it kept comng to our hands briefly even though we had no food. Photo by Matt Wallace.

This count is not an official Christmas Bird Count, but it has a pretty long history now, and it is an important tool to monitor the long-term population trends in the park. If you want to learn more about the count in all areas of the park, come to Birds & Beers this Thursday, February 8, where the Count Organizer Jim Washbrook will present the results and answer questions.

Results of the Calgary and Priddis Christmas Bird Counts will also be presented at Birds & Beers. In case you missed it, here are some of the results from the Calgary Count, showing the species recorded and the numbers of each:
