Flying Squirrels of Calgary

Nov14

I seem to be doing a lot of mammal posts lately, but as birders, we are interested in the entire web of nature.  I find that the more birding I do, the more interested I become in all other animals, and in plants as well.

Last Saturday, Dan Arndt and I, plus assorted wives and girlfriends, took a hike at dusk in the Weaselhead with the intention of finding and photographing Northern Flying Squirrels.  These rodents are strictly nocturnal, so many people aren’t even aware that they exist here.  But in fact they range across the entire northern boreal forest of Canada and Alaska, and down into the continental United States as well.

I first saw these animals in March of 2008 when I attended a Nature Calgary “Owl Prowl”, led by Gus Yaki, to listen for Northern Saw-whet Owls.  We didn’t hear any owls that night (according to Gus, it was Christmas – “the First No-owl”), but as we walked back through the woods in the dark I saw a shape streak through the trees against the dim sky.  I assumed it was a bird going to one of the nearby feeders, but what bird goes to a feeder in the dark?  Then someone shone a flashlight on the trees, and we saw that it was a small squirrel with very large reflective eyes!

Since then Nature Calgary has had annual outings to this spot to see these amazing animals, and we did see them again in 2009 and 2010.  This spring they didn’t show, so I wondered if they were still around.

On Saturday we arrived a little early, so we walked around the forest on the south side of the Elbow River bridge for a while, hoping to see an owl.  Again there was no luck spotting any owls, but we did see one Pine Grosbeak and one Common Redpoll, plus dozens of Canada Geese overhead.  At dusk we headed back across the bridge to the feeders to set up our cameras.

Sunset was at 5:05 pm and two Northern Flying Squirrels glided in at 6:05 pm, right on schedule, as it seems that they make this feeder their first stop of the night, a half-hour or so after it gets dark.  The squirrels seemed reluctant to go right to the feeder – they hid in the trees somewhere for ten minutes or so before we saw them again.  We saw a few more gliding shapes and some squirrel silhouettes on tree trunks, and heard them scrabbling up and down the bark, but never got a good look at them.  Finally, my wife snapped a few shots with a flash when she heard one on the tree in front of her, resulting in a couple of fuzzy images as the squirrel tentatively climbed down toward the feeder. (Click on pictures to enlarge them.)

We will certainly be heading out again in search of the Northern Flying Squirrel.  Maybe someday we’ll get a photo as clear as the one below.

Christmas Bird Count 2011 – Here’s Your Chance to Volunteer!

Nov13

House Finch

The 60th annual Calgary Christmas Bird Count will take place this year on Sunday, December 18th.  There are two ways to get involved – as a birder in the field, or as a feeder-watcher in your yard.

There are over thirty territories in the count circle, so we need to get a lot of birders out in the field to identify and count all the birds.  In recent years the number of field volunteers has dropped below 100, and we’d like to get it back up over that number for this 60th count.

The Count Circle (click to enlarge).

If you’d like to help with this, please consider volunteering.  You don’t have to be an expert birder – there will be at least one experienced birder in each territory, so you will be assigned to help them out.  Most groups will be going out for the full day, but you can participate for a half-day if you wish.

Contact Phil Cram at crampj@telusplanet.net to volunteer, or for more information.  

American Wigeons

Feeder-watchers:

If you are unable to get out birding with us on December 18, you can still participate by spending some time counting the birds in your yard.  You needn’t spend all day at this, but should try to record the maximum numbers of each species in your yard, and the time spent watching.

To participate as a feeder-watcher, you must register to take part, and live within the above 24-km-diametre count circle.  If you are outside the circle, perhaps you have friends who feed birds and live within it – you could persuade them to take part, and assist them with their counting.

Contact Jean Moore at jmmoore@ucalgary.ca or phone 403-282-4162 for more information on the feeder-watch program, or to volunteer.

Northern Flicker

There are several other Christmas Counts in the Calgary region every year.  Keep an eye on our “Free Nature Walks” tab at the top of this page for updates on these, or see the Bird Studies Canada page to find a list of all counts in Canada.

Birds of Elliston Lake

Nov11

A little-known gem in the city is Elliston Lake, a stormwater pond at the east end of 17th Avenue SE.   It is the second-largest body of water (after Glenmore Reservoir) in Calgary.  At times it can harbour an impressive array of waterfowl, as well as some interesting mammals. (Click on pictures to enlarge them.)

Photo by Dan Arndt

When the Friends of Fish Creek group went there last Saturday, the lake was mostly frozen over, but there were still several thousand waterfowl on the few open areas.  (The northeast corner of the lake usually has some open water all winter.)

 The north half of Elliston Lake, looking west.

From 17th Avenue SE, turn south on 60th Street to access the parking lot.

The action actually started before we even got to the parking lot – a Merlin was feeding on a Rock Pigeon on the roadway.  I got a poor shot through the car windshield.

There was quite a bit of traffic, so it abandoned the pigeon and landed on a nearby pole.

Photo by Dan Arndt

A few minutes later we saw the Merlin attack a flock of pigeons above 17th Avenue.

Almost as soon as we started the circuit of the lake, someone spotted a Red Fox out on the ice.

Later, we saw the fox check the shoreline for disabled waterfowl, but it came up empty.

Photo by Dan Arndt

The birds didn’t seem to mind the fox much; they just moved away from the shore.

A close inspection of the masses of Canada Geese and Mallards turned up some interesting birds:

Northern Shoveller (rear centre)

The next picture highlights the size difference between a Green-winged Teal and a Mallard, and shows off the brilliant colour in the teal’s speculum.

Photo by Dan Arndt

A juvenile Barrow’s Goldeneye (below, rear) is identified by having a steeper forehead and shorter bill than the Common Goldeneyes.

Many of the Canada Geese on the lake belonged to one of the small, short-necked subspecies, but there was one goose in among them that was smaller yet – only slightly bigger than a Mallard.  At first I thought it might be a Cackling Goose, but those are Mallard-sized and have a very stubby bill.  This goose (lower centre) is just a very small subspecies of Canada Goose.  Compare it to the Mallards just behind it.

Here is a Gadwall (rear):

There were a few Ring-necked Ducks:

Below are two Ring-necked Ducks (right foreground) with Lesser Scaup:

This Lesser Scaup landed on the ice and tried to walk back to the open water, but slipped…

…so he just gave up and sat down.

We also saw some Common Redpolls feeding on birch seeds:

Two Rough-legged Hawks flew over, the second one chased by a Common Raven:

Near the end of our tour, some Canada Geese walked out on the ice, then flew off…

Bird Profile: Bohemian Waxwing

Nov5

A rush of wings, followed  instantly by  high-pitched trills break the silence. It is a cold, wintry scene, snow falling slowly from the never-ending sheet of clouds that blanket the sky in a gloomy grey. Standing still, nothing is to be heard; no cars, no people, and, above all, no birds. Just when it seems as though the entire world has gone into a peaceful slumber, the calm is broken by the sound of nature.

When they descend in hundreds, berries don’t last long at all. These birds are highly social and travel tight together, descending en masse on fruit bearing trees, where they proceed to rapidly consume thousands of berries. A very hardy bird, the Bohemian Waxwing toughs out the frigid winters of northern latitudes, enduring harsh conditions.The waxwing is both gregarious and elegant with a slick crest, and soft, silky plumage; it is deemed attractive by many. Named for the red, drop-shaped, waxlike tip on their feathers, this bird has warm grey-brown plumage, a black patch through the eye and a yellow-tipped tail. Bohemian Waxwings are berry aficionados and during winter, survive on the fruit of trees such as mountain ash and juniper, but also eat saskatoon and choke berries. Such a heavy reliance on one source of food can greatly affect a birds population and will cause much fluctuation. If there is a high population one year and a low fruit crop the same year, many waxwings will disperse in winter further south out of their regular mapped range. These years are known as irruptive years and are cherished by southern birders who do not usually get the opportunity to observe these birds.

I love witnessing large flocks of Bohemian Waxwings, it is possible to hear the whir of thousands of wings as they land, the twittering as they communicate endlessly, and the soft thud of berries as the fruit falls into the snow below, dropped by  a careless tug from the beak of a waxwing. Sometimes, after the flock has left, the snow will be littered with bright red berries. Then as cars and people pass over the fruit, the snow will be stained a rose color, evidence of the masses of birds that banqueted there.

Remember next time you are shoveling snow in -30 degree weather; you are privileged in that you can witness this elegant species brightening up the dull grey day. These birds are truly northern and hardly extend into the U.S. They are definitely one of the things I will miss most about Calgary winters.

Join Project Feeder Watch

Nov4

Backyard birdwatchers across Canada are invited to take part in the 25th season of Project FeederWatch, from November 12 through April 6. With each season, FeederWatch increases in importance as a unique and indispensable monitoring tool for more than 100 bird species that winter in North America. Last year, over 2,500 Canadians and 11,000 Americans counted backyard birds; their observations help scientists better understand the health and behavior of birds – an important indicator species for the well being of our planet.

Each checklist submitted by ‘FeederWatchers’ helps scientists at Bird Studies Canada and the Cornell Lab of Ornithology learn more about where birds are, how they are doing, and how to protect them. Participating in Project FeederWatch is a great way for families and friends to connect with nature, have fun, and help birds. You do not have to be an expert to participate – they’ll send you a poster of common birds, and help is just a phone call or email away.

Participants choose how much time they want to dedicate to the project. They are asked to select their own two-day count period once every two weeks, and then count for as little as 15 minutes (or as long as they like) on one or both of those days. Sightings are entered online at www.birdscanada.org/volunteer/pfw or reported on paper data forms and mailed in at the end of the season.

Data from FeederWatchers have helped scientists learn about changes in the distribution and abundance of feeder birds over time, expansions and contractions in their winter ranges, the spread of disease in bird populations, and the kinds of habitats and foods that attract birds.

Loon Survey, Part Three

Nov2

It’s high time I updated the Loon Survey I did for Bird Studies Canada this past summer. You can read about the survey, and see pictures of the eggs, fledglings, and adult loons, on my previous posts: Loon Survey, Part One, and Loon Survey, Part Two.

In late August I returned to Leisure Lake, near Bragg Creek, to check on the Common Loon family.  The purpose of the third visit, late in the season, is to see if the young loons have survived.  Like all birds, loons have a high rate of mortality among fledglings.

I was happy to find that the two young, still in their brown plumage, were doing well.  They were starting to look like adults. (Click on any picture to enlarge it.)

  Juvenile Common Loon, about two months old.

The two juveniles with an adult.

However, despite making a long slow circuit of the entire lake, I only saw one of the parent loons.  I thought that perhaps one of the adults was hiding on shore somewhere, but I’ve been told that loons are so ungainly on land that they only go ashore to incubate their eggs.  It’s possible that it was in the reeds somewhere and I missed it, but that seems unlikely.  Perhaps one of the adults departed for the wintering grounds earlier than the other adult and the young.  I don’t know if they normally do that or if they all leave together.  The other possibility is that the missing adult succumbed to disease or a predator.  It will be interesting to see what happens there next spring.

If you want to participate in the Canadian Lakes Loon Survey, there are plenty of unmonitored lakes with loons on them.  Contact Bird Studies Canada for more information.  Here is a link to the Canadian Lakes Loon Survey page.
