2015 Peregrine and Osprey Nest Cams

Posted by Bob Lefebvre

Ospreys are now back in the city, and Peregrine Falcons have been back for a few weeks. The regular nesting Peregrines returned to the University of Calgary a month ago, and as of yesterday, four eggs were in the nest. That should be it for egg-laying, so now you can watch until they hatch and the young fledge.

Watch live here, and there is a link where you can view the nest on YouTube, and comment on what you see.

Meanwhile, both the male and female Osprey were back at the Calgary Zoo nesting platform by April 16. You can watch live here.

Links to both cameras will be at the top of our right-hand sidebar until the birds have left, so you can always come to Birds Calgary for a quick link to the nest cams.

We have now removed the Snowy Owl sightings link for the season. You can check eBird for all this year’s Snowy sightings here.

April Birds & Beers

The next Birds & Beers event in Calgary will be held Friday, April 17 at the Horton Road Legion, 9202 Horton Road SW, from 6 to 9 pm. Everyone is welcome, including kids if they are accompanied by an adult. So come on out any time after six to chat with your fellow birders.

More information and a map can be found on the event’s Facebook page.

The eBird Calgary 2015 competition will be awarding the prizes for the first challenge, and there will also be a door prize. The event is not just for people in the competition but for anyone who wants to socialize with other birders and have a drink and a bite to eat.

Passing the Torch

Posted by Bob Lefebvre

I think that most birders would love to live in a world with stable and prospering bird populations so that we could study and enjoy birds merely as a pleasurable hobby. Unfortunately that is not the case, as birds and other animals face serious threats almost everywhere on the planet. Many birders now spend much of their time and energy trying to combat habitat loss and other threats to the birds.

Traditionally, a typical birder is middle-aged or older. It is often a hobby taken up seriously by adults after their children have left home. When we get together for meetings and field trips, the majority of us are over 50 years old.

The percentage of the population that is interested in birds and birding is quite large – birding is second only to gardening as a hobby in North America. But only a small percentage of those backyard birders do it seriously. Consequently, our political voice is not as strong as it could be, or as it needs to be to effect positive changes for our natural world.

Most children have an innate fascination with nature and truly enjoy seeing birds and animals, and learning about the natural history of the earth. Unfortunately this eagerness to appreciate nature is often not fostered, resulting in a waning interest in nature and a lack of awareness of environmental issues. We need to raise a new generation that can be a strong voice for conservation.

Paul PGPhoto by Paul Gee. Many of us have seen a look of  delight like this when sharing our birding experiences with children, or with adults who are new to birding.

One of the most important things we can do as birders, as parents, grandparents, aunts and uncles, is to teach the children in our lives to respect and understand nature, and to be a force for conserving and restoring our natural heritage. This is one of the main motivations for many of us who do things like writing for bird blogs, leading field trips, running bird counts, and organizing birding competitions.

There are many opportunities to get and keep kids interested and involved. Nature Calgary offers many field trips of all kinds, which are free and open to everyone. Children can attend as long as they are accompanied by a parent or guardian. Similarly, the Friends of Fish Creek birding course welcomes any paid adult participant to bring children along, for which they are charged only a nominal $5 fee per child for the entire course.

One of our goals in organizing the eBird Calgary 2015 Big Year birding competition was to try to encourage more children (and adults who are novice birders) to get involved in the local birding community. As of today we have 23 beginners, and 13 youths under 17 registered. We would love to have more, and the deadline to enter is Tuesday, March 31.

If you can’t get out with your kids, there is still a lot you can do. I know of one parent in Calgary who takes his three kids on a nature walk to a new location every Saturday – just to get out and enjoy the birds, mammals, flowers, and trees. You could do this in your own yard or local park. You can also make a point of regularly watching nature shows on TV with them, and encouraging them to read about nature.

I ran into one of the youths in the competition early this year, and talked to his mother about his interest in birds. She regularly drives him to various parks and other locations to look for birds, and told me that birding has changed their lives. The following is an excerpt from an email she sent me:

In an age where kids are connecting more with social media and video games, I am very grateful that my son is growing up connecting to the natural world by his own choice. I have not yet bought him a cell phone because I want him to be in his world first, thinking and aware, without electronic distraction. Birding really requires that one is fully present…and it is clear he is learning to use his senses to hear and see birds. Through birding, he is excited to sleuth out (this is a phrase he has used with me) new species; happy to spot birds that he’s only seen in his books or posted by others.

I really should write the producers and actors of the movie “The Big Year” to thank them….that movie lit the fire for my son’s interest in birding. His next steps were birding sites like Nature Calgary and then eBird. Although he still likes a few video games, a good deal of the time he is on eBird, reading his new Sibley’s, looking at his photos…or now setting up his Flickr account.

Birding HAS changed our lives. We were pretty stuck inside, lots of screen time (computer and TV) and it seemed like I was always instructing him on something or asking him to stop the video games on the computer. Ours days were often not as positive as I would have liked. It is delightful to have birding where he is on point rather than me – both for technical content and motivation. I view this as a natural progression of independence for him and it’s wonderful for me to relax and just be with him. When he found the Northern Saw-whet Owl the other day we were both jumping up and down and high-fiving it in the frigid weather :) He was thrilled to find it (our second trip looking) and it’s great to see him so happy. Those are golden moments for me…both to be included in the find and to celebrate with him. Our birding trips are some of our happiest times together. He researches and plans, I drive, the world slows, we look and listen…and companionably walk together. Wow, that’s really what I want in life right now….for both of us!

I am acutely aware that my time with my son is limited; soon (4-1/2 years) he will be off to University. Birding has refocused our priorities and energy towards something rewarding and enjoyable and it’s getting us out and moving. I really believe that birding is drawing us closer while providing him with a pursuit he can call his own his whole life. It’s the best of what we like – books, travel, a worthwhile quest… and beautiful birds. My son said it himself the other day: “Birding really helps you appreciate things.”

What a gift it is, for both the child and our world, to be able to instill that sense of wonder and belonging. I welcome you to share this post, and to please share with us your stories of how connecting with nature has affected your lives.

Birding Competition Update – March

Posted by Bob Lefebvre

The first of the mini-competitions within the eBird Calgary 2015 Competition was to find the most species within the circle in the first three months of the year. With just a few days to go there are some close races. As more spring migrants arrive every day, there is still time to find more species.

Here are the leaders in the three categories as of March 28. In the Experienced category, note that Daniel Arndt and Andrew Hart are not eligible for prizes – Daniel is a member of the organizing committee, and Andrew is President of Nature Calgary.

Youth

Aidan Vidal                       60 species
Simone Pellerin-Wood        57
Birdboy Canada                 48

Beginner Adult

Aphtin Perratt                   65
Nicole Pellerin                   63
Darlene Shymkiw              62

Experienced Adult

John Thompson                 90
Andrew Hart                      85 (not eligible for prizes)
Daniel Arndt                      84 (not eligible)
Blake Weis                        82
Brian Elder                        77
George Best                      74

Ebird Usage

One of our goals for the competition was to greatly increase the use of eBird by local birders. The number of checklist submissions for the first three months of the year is way up over last year, and we hope to see an even bigger increase in the coming months. Note that the competition area includes all of Calgary county, plus parts of three other counties, so I have compared numbers for Calgary and for all of Alberta to get an idea of the increased usage of eBird.

Number of eBird checklists submitted, January to March:

2014 Alberta – 4,996

2015 Alberta – 6,498

2014 Calgary county – 1,919

2015 Calgary county – 3,484

To a close approximation, the entire increase in eBird usage in Alberta (up 30%) comes from the increase in Calgary county reports.

The number of bird species reported is also way up. This probably is mostly due to the milder conditions and an increase in overwintering birds this year, and perhaps some earlier spring arrivals than last year. Nevertheless, as more birders get out and use eBird, we do get a more complete picture of all the species in our province and local area.

Number of species reported by month:

2014 – Alberta

January    101

February   103

March       128

2015 – Alberta

January    111

February   105

March       140

2014 – Calgary county

January     78

February    78

March       103

2015 – Calgary county

January     91

February   87

March       122

There have been a total of 1,216,532 individual birds reported in Alberta so far in 2015 (752,772 in Calgary county). That’s a lot of data in the eBird database!

As of today we have an even 100 participants in the competition, with a few days still to go until the March 31 deadline (13 Youth, 23 Beginner Adult, 64 Experienced Adult). If you or anyone you know wants to join, email us at ebirdyyc@gmail.com. We’d really like to increase the number of youths and beginners involved. There is no set time commitment, and even if you only get out a few times in the year, it helps to contribute to our knowledge of local birds, and of course it is good for you too! Don’t worry too much if you’ve missed out on the first part of the competition; you can still get all the winter species next November and December.

In the next few days we will announce the April Birds & Beers event, at which we will award the prizes for the first mini-competition. We are planning some regular field trips to target some of the difficult-to-find birds in the circle, and later in the spring, a Big Day field trip to see how many species we can find in the circle in one day. In the meantime there is a full slate of Nature Calgary field trips that you can participate in, and the Friends of Fish Creek are taking registrations for the 12-week Spring Birding Course, which starts on March 30.

Join Us For the Birding Competition!

The deadline to enter the Calgary birding competition is March 31. Join over 100 other birders who are trying to see as many species as they can in the Calgary area in 2015.

Furry Friday: Flying Squirrels

Update: For the first time, the group (45 people) did not get to see the Flying Squirrels on March 20, and we didn’t hear any Saw-whet Owls either. It was a very humid, misty, foggy night with the temperature near freezing, so that may have had something to do with it.

—————-

Next Friday, March 20, Dan Arndt and I will lead the annual Nature Calgary outing to the Weaselhead to see Northern Flying Squirrels. This is a popular outing, likely because people don’t often get an opportunity to see these animals. It can also be challenging, because we often have to wait for over an hour in the cold and dark before the squirrels make an appearance. But if you are patient there is a very good chance you will see these elusive creatures. In over a dozen trips to see them, I think we have only missed them twice. We generally get to see them glide, and we see them up close at a particular bird feeder which they apparently visit each night, looking for seeds that the birds have overlooked (we re-stock the feeder just before the field trip so that they will stay and feed for a while).

For birders, we often hear Northern Saw-whet Owls and sometimes other species.

If you want to join us, we meet at the north Weaselhead parking lot, 37 Street and 66 Avenue SW, at 8 pm, Friday March 20. Here is the information about the field trip on the Nature Calgary site.

Many people are not even aware that we have flying squirrels in Calgary (I wasn’t until we saw one at this location in 2008), but they are in fact common throughout the boreal forest, and probably in the city as well. Because they are nocturnal they aren’t often seen.

Most of the photos below were taken last spring on one of our scouting trips. We set up in the bush within ten feet of the feeder, and were able to get great looks. All photos by Dan Arndt, March 26, 2014, except as indicated.

Below is a Northern Flying Squirrel approaching the feeder after landing higher in the tree. You can see the wide flattened tail which acts as a rudder and as an additional gliding surface. (This photo taken March 23, 2012, by Dan Arndt.)

The next shot shows the large eyes and the furred flap of skin with a dark edge between the wrist and ankle. This is called the patagium, and it forms the main gliding surface when the legs are extended. (This photo was taken by Dan Arndt on March 17, 2012.)

Below, a Northern Flying Squirrel at the feeder:

Below, Feeding. Note the patagium extending from the forward part of the wrist. There is a cartilaginous rod several centimeters long (inside the patagium) jutting out from the wrist, which helps to support the skin.

13440577024_1e3b75555a_k

The remaining photos were actually taken before the 2014 flash photos above. We use a red light to locate the squirrels. Apparently they can’t see these wavelengths, so it doesn’t disturb them, and we can see them approach. Once they are feeding they settle in and are more tolerant, and do not usually leave even when you use flash photography or approach them more closely.

Here is another post that Dan wrote after our 2012 field trip: Barred Owls and Flying Squirrels.

More facts about the Northern Flying Squirrel:

  • occurs throughout the forested regions of Canada, except Vancouver Island and the island of Newfoundland
  • absent from the treeless arctic and great plains
  • the similar Southern Flying Squirrel occupies the eastern US and parts of southern Ontario and Quebec
  • the Southern species is rapidly expanding northwards, and is hybridizing with the Northern
  • since Northern Flying Squirrels are nocturnal and shy, they are often thought to be scarce, but are in fact well distributed and and common
  • with a population density of 0.1 to 3.5 squirrels per hectare, they likely have the highest total population of any squirrel species in Canada. This is a minimum of 260 squirrels per square mile in the poorest parts of its range, up to over 900 per square mile in food-rich areas
  • they are active all year, and breed from March to June
  • usually nest in tree cavities (abandoned nests of other squirrels or birds), but may construct a drey in summer
  • are clumsy walkers
  • can glide up to 65 metres, dropping about 1 metre for each 2 metres of glide length
  • are very maneuverable, able to make a 90-degree turn in flight, or even to corkscrew around a tree and land on the same tree at a lower point
  • after landing on a tree, they immediately scurry around to the other side, in case they are being pursued or watched by a predator
  • are preyed upon by owls, hawks, weasels, coyotes, raccoons, bobcats, lynx, wolves, foxes, cougars, and domestic cats
  • are especially vulnerable to large nocturnal owls like Great Horned and Barred Owls
  • in Oregon, Northern Flying Squirrels make up about 50-60% of the diet of the endangered Spotted Owl, which consumes an average of 260 squirrels per owl per year
  • Northern Flying Squirrels eat mainly fungi (especially truffles) and lichen, along with seeds and nuts of trees. They supplement this with fruit, tree sap, buds, insects, small birds and eggs, small mammals, and carrion
  • they are a keystone species, vital to their environment due to their feeding activities which disperse tree seeds and the spores of symbiotic fungi throughout the forest

Join us next Friday for a chance to see these amazing animals!

My main source for information on Northern Flying Squirrels was the excellent book The Natural History of Canadian Mammals by Donna Naughton.

Sunday Showcase: Hawk versus Kingfisher

Posted by Bob Lefebvre

On one of our Friends of Fish Creek birding course field trips last fall, we were treated to an amazing chase in the Weaselhead Nature Area. We were in the woods just past the bridge over the Elbow River when I heard the distinctive rattle of a Belted Kingfisher. We hurried back to the river to try to see this bird, which, given the late date (November 8) was likely attempting to overwinter in Calgary, as they sometimes do.

Suddenly the Kingfisher took flight, and a small hawk appeared and gave chase. We later identified it as a Sharp-shinned Hawk. In all, it tried five times to catch the Kingfisher out of the air, with a short break between attempts three and four, during which both birds rested on nearby perches. The Kingfisher actually moved to a perch closer to the Hawk, apparently to keep a better eye on its movements.

The amazing part of this chase was the the Kingfisher escaped each time the Hawk got really close by splashing down in the river! Then the Hawk would pass by, and the Kingfisher would emerge form the water, calling loudly. Of course, Kingfishers hunt in this way, diving into the water after small fish, but Sharpies are used to catching their prey in the air. The Hawk didn’t want to get its feet wet, and never managed to get its meal.

A couple of the people on our walk got a few photos of this encounter.

The 12-week Spring session of the Friends of Fish Creek birding course begins on March 30, 2015. See this post for more information.

Spring Birding Course 2015

The Friends of Fish Creek are now taking registrations for the very popular Spring Birding Course. New for this spring is the option to go out twice a week rather than just once. These courses are a great value for all the time you get to spend to spend in the field, and the rate for youths sixteen and under is still only $5 (with a registered adult) for the entire twelve-week course! Register online here.

Spring Birding Course 2

Sunday Showcase: Eagles of Beaverdam Flats

Posted by Bob Lefebvre

The lower Bow River in Calgary, downstream of the weir, is a great spot for winter eagle-watching. There is a plentiful food source, consisting of dead or dying Canada Geese, Mallards, and other waterfowl. Among the tens of thousands of birds on the open parts of the river, there are always some that are sick or injured (some of them wounded by hunters). Bald Eagles will readily scavenge the dead birds.

11281326655_fd22bd9a73_kNear-adult Bald Eagle eating a Mallard, Beaverdam Flats, December 8, 2013. Photo by Dan Arndt.

The Bow River is warmed by runoff from the waste-water treatment plants and other city runoff. Because of this, the Bow below downtown Calgary is often the only large body of open water in the area during cold winters. (This has only been the case since about 1975. Before that, there were no waterfowl here in the winter since there was no open water. There were very few eagles seen here until about 2000, as they recovered from critically low numbers caused mostly by DDT poisoning.) These days, good numbers of eagles, mostly juveniles, are seen on the river in winter at the Inglewood Bird Sanctuary, Inglewood Golf course, Carburn Park, Beaverdam Flats, and all the way down through Fish Creek Park. The largest concentrations seem to be at Carburn and Beaverdam.

When the wind is blowing from the west, as it often is, you can watch the eagles soaring right over your head. Here are some photos taken by John Stegeman on a Friends of Fish Creek outing in January.

Occasionally the eagles will gather in a small area and you see quite a number of them together. Here is a photo taken in January by Ron Friend.

Eagles- Beaver Dam Flats-Jan 21,2015 029Five Bald Eagles and four Common Ravens in one tree, Beaverdam Flats, January 21, 2015. Photo by Ron Friend.

A few years ago I saw fourteen juvenile Bald Eagles in one tree at Carburn Park. I mentioned this to Gus Yaki, and he said he had seen seventeen at once at Beaverdam Flats, and he once met a person from the adjacent Lynnwood neighbourhood who claimed he had a photo of an incredible thirty-one!! (He agreed to send Gus the photo but either couldn’t find it or lost the email address – if you’re out there, please send it to us!)

Thirty-one might be the unofficial Calgary record, but here we have an amazing photo of twenty-six Bald Eagles (and two Common Ravens) taken at Beaverdam in January 2009 by Ron Kube. (Click the photo to enlarge it. It can be hard to spot every last one, but there are indeed 26 eagles. The one that’s really hard to see is just above and to the right of the adult that is at 9 o’clock, a little in from the left edge. The ravens are together at the lower centre of the photo.)

Tomorrow, Family Day, will present a good opportunity to look for eagles in Calgary. Dan Arndt and Rose Painter are leading a Nature Calgary field trip to Carburn Park. See the Nature Calgary field trip page here.
