The final Birds & Beers of the 2023-2024 season is this coming Thursday, June 13th. As usual, we meet from 5 to 9 pm in the big ballroom at the Legion, 9202 Horton Road SW. We will feature a presentation by Diane and Bob Leonhard about their recent trip to Central Amercia.
Here is the presentation description:
Between January 28 and February 7, 2024, we spent ten days with Eagle Eye Tours in Belize and Tikal National Park, Guatemala. During this time we saw approximately 270 species of birds, including 75 lifers. After starting in Belize City, our first few days were spent at The Jungle Lodge in Tikal where we encountered some incredible birds, such as the Ocellated Turkey, Boat- billed Herons, several wood-creepers, the rare Orange-breasted Falcon, the spectacular Agami Heron and numerous others. We then returned to Belize, where we spent three nights at the Jade Jungle Lodge in the hills of western Belize. Here the highlights included the fabulous food and an incredible look at a spectacular Spectacled Owl. In the Mountain Pine Ridge area we got a good look at the huge King Vulture and excellent views of a very co-operative Rusty Sparrow. Our final few days were spent at Birds Eye View Lodge in the Crooked Tree area north of Belize City. Here we got great looks at many new birds including, Yellow-lored Parrots, Yucatan Jays, Yellow-headed Parrots, Aplomado Falcons, Black-collared Hawks, Snail Kites and many more. A real treat was the excellent look at the scarce and secretive Yellow-breasted Crake. It was a wonderful tour with two excellent guides and a nice group of participants.
This presentation, with many photos of the birds, will begin at about 7 pm. Come early if you want to visit or have a meal and a drink. Everyone is welcome!

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.
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.
The Apple Podcasts page about Birds of Alberta.
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.
The podcast is available on Spotify and other platforms as well.
Check out the Birds of Alberta podcast – it is a welcome addition to Alberta’s wildlife media.

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.

The May Species Count covers a huge area in the Calgary region. Volunteers go out to their designated routes on either the Saturday or Sunday (or both) and record all the bird species they see, and the numbers of each. There will likely be several routes available in the city and in rural areas. You should have a choice of a small or large city area, or a large rural territory or a part of one.
The birds above were seen on the 2023 May Species Count in the Longview Area, May 28, 2023. Photos by Bob Lefebvre.
Results are submitted by eBird and you are encouraged to get some photographs too. If you are inexperienced and not confident to go out on your own, you may be placed with an existing group.
The 80-km radius Calgary Count Circle with the rural territories numbered. There are numerous different habitats represented, including prairie, parkland, urban, boreal forest, and foothills.
The routes available will be known soon and I will post updated information. If you are not already slated to take part and are interested to join us, or for more information, email the organizer Andrew Hart at andrewhartch[at]icloud.com. Andrew is out of the country right now so if you just want more information about the count, email me at birdscalgary[at]gmail.com.

Featuring a presentation by Stephen Boucher on winter birding in the Ebro Delta, Spain.
Birds & Beers continues next Thursday, May 9th, from 5 to 9 pm at the usual location, the Royal Canadian Legion at 9202 Horton Road SW in Calgary. At about 7 pm there will be a presentation by Stephen Boucher on a trip he made in November 2023 to the Ebro Delta and the Catalan Pyrenees in N.E. Spain.
Everyone is welcome at Birds & Beers. We meet in the large ballroom. Come early if you want to have something to eat or drink, or just come for the presentation if you wish.
The City Nature Challenge is unique in that anyone can participate anywhere in the area from April 26-29. But if you want to take part with an organized group there are many events being offered.
To contribute to the CNC you have to post your observations on the iNaturalist app or website. If you would like to learn how to use iNaturalist, or if you need a refresher or have any questions about the CNC, organizer Matt Wallace is offering a tutorial tonight, Tuesday April 23, at 7 pm. This will be done over Zoom. Here is the link to the meeting.
The CNC area includes Calgary, Cochrane, Airdrie, Chestermere, Okotoks, Foothills County, and Rocky View County. Any iNaturalist obserations made in this area from April 26-29 will contribute to this project.
Matt has organized a number of events throughout the weekend. These include all-day blitzes, birding walks, and more specialized events such as pond study and a pollinator walk. Click the link below to see all the events!
For Nature Calgary members, there are three events on Sunday April 28 which are not full. These include a Birding Blitz on St. Patrick Island near the Zoo, a Bryophyte Blitz in the Weaselhead, and a Plant Walk in Glenbow Ranch Provincial Park. See this page to register.
More information from Matt Wallace:
April 26-29 take photos of wild plants and animals in your yards, neighborhoods, and favorite parks. Then upload your observations to the iNaturalist app or to iNaturalist.ca before Midnight May 5. This is the sixth year I have organized the Calgary CNC and it has grown immensely. There are over 700 cities involved worldwide and we are competing with them to see how many observations we can make, the number of species we can document, and the number of people we can get to participate. The two metrics I am most concerned with for our area are the number of observations and the participants.
My personal goal for CNC is that we can make a combined 10,000 observations or more during the four days. I also hope that we can make 250K observations by 2025 (We are currently at 169,000 observations just in Calgary). If each of us were to make even 10 observations over the weekend, we could make the CNC target and could be the top-performing Canadian city (49 participating Canadian cities this year).
The area which you can participate in during CNC includes: Calgary, Cochrane, Airdrie, Chestermere, Okotoks, Foothills County, and Rocky View County. Participate in groups, at events or even go exploring on your own. Heck, make a “big day” out of the four days if you’re up for the challenge. I have helped to organize around 15 events across the region all happening Friday-Monday which can all be found on the website below.
Types of subjects we love to see shared on iNaturalist include Birds, Plants, Butterflies, Insects, Fungi, Lichens, Mosses, Mammals (pretty much everything and anything but NO people or pets).
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:
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.

While you’re out there, you can also get photos of non-bird biodiversity with your camera. Maybe you won’t know what species you have, but iNaturalist has an artificial intelligence that can help with the ID, and even if you have no idea, other iNaturalist users will help to identify everything.

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):

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!
Diane Stinson will present on Canada’s High Arctic.
Next Thursday, April 11th, we will have another Birds & Beers event at the Legion at 9202 Horton Road SW in Calgary. The event starts at 5 pm and at 7 pm there will be a presentation by Diane Stinson on a trip that she and her husband Rob took to the High Canadian Arctic last summer.

Canada’s High Arctic – Diane Stinson Rob and I went to Canada’s High Arctic in August last year. The original itinerary had us exploring Ellesmere and Axel Heiberg Islands, including stops at Devon and Beechy Islands. The wildfires in Yellowknife changed that. Instead, we started in Iqaluit, sailed north along the east coast of Baffin Island through the Davis Strait and Baffin Bay, crossing the Arctic Circle, and into Lancaster Sound. There we explored areas on Devon and Beechy Islands (Franklin Graves), finishing in Resolute. While we didn’t see some of the bird species we were expecting initially, we did see some great birds (largest colony of Northern Fulmar in Canada), as well as major mammals (polar bears, walrus, Bowhead Whales).
The expedition team of experts included Noah Strycker (author of “Birding without Borders” – a book about his global big year in 2015) and three other ornithologists. A historian, an archeologist, a glaciologist, and a marine biology expert all gave excellent talks. Our outings included zodiac cruising, shore walks, and helicopter excursions. We experienced an amazing “Tundra to Table” dinner and the “Polar Plunge,” before exploring Resolute.

Everyone is welcome to Birds & Beers! Come for the good food and drinks that are available, visit with your fellow birders, and stay for the presentation!
Mountain Bluebird, photographed by Carole Steeves,Carburn Park, Calgary, 21 March 2024.
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.

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.
