Weaselhead Bridge – Ring Road Petition

Posted by Bob Lefebvre

Most Calgary birders are aware by now that the ring road construction adjacent to the Weaselhead Nature Area in SW Calgary is well under way. A huge area has been cleared in preparation for building a bridge over the Elbow River.

This project has been discussed for decades, and birders have been very concerned about building a bridge and highway through such an environmentally sensitive area. I think it has long been assumed that when the time came, if it did, the builders would be sure to follow best environmental practices to minimize the impact on this area. In particular, it was hoped that a clear span bridge like the Stoney Trail bridge over the Bow River would be built. Instead, the plan is to build an earthern berm or cut-and-fill bridge, which will fill in the valley up to the road level for most of the span, essentially forming a dam across the floodplain. This design will have many negative consequences for the birds and other wildlife in the valley, and create a great many problems during flood events.

The Weaselhead Nature Area is on the right, and the ring road construction showing the diversion of the Elbow River on the left. As you can see, there has already been a stunning amount of disturbance, cutting off the Weaselhead from the ecologically diverse Elbow Valley to the west. Photo from the website http://www.yyccares.ca/recent_pictures.

A concerned group of local citizens is petitioning the Alberta Government to build a better bridge over the Elbow. Please visit their web page YYC Cares. There is a great deal of information on their site, and you can sign the petition there.

Nature Calgary’s Big Week of Birding

Posted by Bob Lefebvre

For many years Nature Calgary has held a Big Day on the Victoria Day holiday – an attempt to find as many species as possible in one day, in this case all of them inside the Calgary city limits (we had 116 species this year). During the 2015 Calgary Birding Competition we decided to add a Big Day in the Calgary Region–the 80-km diameter circle centred in Calgary. We did the trip again last year. In both cases we saw lots of good birds (151 species in 2015, and 132 in 2016) but it is a long day with quite a few dead stretches of driving.

For this year, we decided to try something new: A Big Week instead of a Big Day in the 80-km circle. There will be a series of field trips offered from June 4 to 10, and we will try to reach a cumulative total of 175 species on these trips.

Most of the trips will be led by myself, Andrew Hart, and Rose Painter. We will kick it off with a day-long trip to the northwest corner of the circle, around Water Valley, on Sunday June 4. The final day will feature another long trip to the south and southwest. Both of these trips require registration because car-pooling will be required and spaces will be limited.

There will also be several field trips offered during the week, including trips inside the city to the Weaselhead and Inglewood Bird Sanctuary. A couple of other trips will be Twitch ‘n’ Tours, our term for for a field trip with a known starting point but for which the destinations are not decided until the last minute, so that we can chase rare birds or ones we have not been able to find so far.

If you want to see how many species you can find in the Calgary region in one week in June, join us for some or all of these outings. See the Nature Calgary field trip page for details and to register.

Weaselhead and North Glenmore Park in Early April

Posted by Bob Lefebvre

For the first week of the Friends of Fish Creek Provincial Park (FFCPP) Society’s spring birding course, the groups birded the Weaselhead from the north parking lot down to the other side of the bridge over the Elbow River, and North Glenmore Park, including the stormwater ponds opposite the canoe club. The goal was to look for some spring migrants such as American Tree Sparrows in the Weaselhead and for Swans on Glenmore reservoir, and possibly Snowy Owls on the remaining ice.

Max Ortiz Aguilar went with the Sunday morning group on April 9th and took photos of some of the birds and mammals they saw, including the Trumpeter Swans shown above. Glenmore Reservoir is a good place to find migrating swans in spring once the ice begins to go out. (All photos taken with a Canon 6D and a Tamron SP 150-600mm.)

In the Weaselhead, the group spotted American Tree Sparrows.

Tree Sparrows are arctic nesters and an early migrant in the spring. Sometimes a few will overwinter here. Note the reddish streak behind the eye, the two-toned bill (black above, yellow below) and the dark central breast spot. These features distinguish it from the similarly rusty-capped Chipping Sparrow, a species which is common here in the summer but which doesn’t arrive back until early May.

The Weaselhead is a great place to find mammals too. Snowshoe Hares are common, and are now mostly in their brown summer coats.

Furry Friday: Snowshoe Hare

Tony LePrieur photographed this Snowshoe Hare in the Weaselhead Nature Area of Calgary on February 20, 2017.

Snowshoe Hare, Weaselhead, February 20,2017. Photo by Tony LePrieur.

Snowshoe Hares (also called Varying Hares) can be found in the city in wooded areas like the river valleys, Fish Creek Park, the Weaselhead, and Griffith Woods Park. They are smaller and have shorter ears and tails than the common White-tailed Jackrabbits you see in residential neighbourhoods and open fields. Jackrabbits have black-tipped ears and a longer white tail. Snowshoe hares have huge hind feet, as their name indicates.

Although they are usually quite common in places like the Weaselhead, they are secretive during the daytime and are rarely seen. You often see their tracks in the snow when birding in these wooded areas. Snowshoe Hares also blend in to their surroundings very well – the white winter coat you see in this photo will soon turn to a rusty brown to help camouflage it during the summer months.

Pileated Woodpeckers

Posted by Bob Lefebvre

The spectacular crow-sized  Pileated Woodpecker is always a treat to see, and they are not very shy birds, so occasionally you can get great close-up looks at them. They are not common in Calgary. Look for them in three areas: Around the Glenmore Reservoir, including the Weaselhead, and upstream on the Elbow River through Griffith Woods Park; The west end of Fish Creek Park; The east end of Fish Creek Park on the Bow River, and north on the river as far as Carburn Park. They are year-round residents here, so look for them any time you are out in these parks. If you live near these areas you may also get them coming to suet or nut feeders occasionally.

All photos by Tony LePrieur.

Pileated Woodpecker (male), Bebo Grove, Fish Creek Park, December 4, 2016.

In the above photo you can see the distinctive rectangular hole that these birds make when feeding. They eat Carpenter Ants, which often infest large trees and deadfall. If you see a fresh hole like this, often near the base of a large tree, you will know you are in a Pileated Woodpecker’s territory.

Female Pileated Woodpecker, Bebo Grove, Fish Creek Park, December 4, 2016.

The female above (likely the mate of the male in the first photo) is distinguished from the male by the black stripe from the bill to the throat, which is red in males. In addition, the red crest does not extend all the way to the front of the head on the female as it does on the male.

The nest hole of a Pileated Woodpecker is a large oval, usually high in a dead tree, or occasionally in a power pole (as seen in Griffith Woods Park). The male will make a new nest hole each year.

Below are more of Tony’s photos of Pileated Woodpeckers in Calgary.

Winter Birds of the Weaselhead

Posted by Bob Lefebvre

Many local birders have been heading down to the Weaselhead Nature Area recently to see several owl species, notable a Barred Owl, which is a species not often seen in the city.

The Barred Owl is usually seen on the north-facing slope of South Glenmore Park just above the Weaselhead. In the Weaselhead proper there have been sightings of a Northern Pygmy Owl, Great Horned Owls, and a Northern Saw-whet Owl this month.

The Weaselhead is a great place for winter birds as it attracts the visiting winter finches as well as many of our resident birds, and it has a variety of mammals as well. Below are some birds and mammals of the Weaselhead photographed by Tony LePrieur.

Pine Grosbeak, male, Weaselhead, January 8, 2017.

Pine Grosbeak, female/immature, Weaselhead, January 8, 2017.

Pine Grosbeak, male, Weaselhead, January 21, 2017.

Pine Grosbeaks are here in small numbers this winter and the Weaselhead is probably the best place to find them. They readily come to the feeding stations along the main path.

Bohemian Waxwing, Weaselhead, January 21, 2017.

Bohemian Waxwing, Weaselhead, January 21, 2017.

Bohemian Waxwings roost overnight in the Weaselhead in huge numbers but might be found there at any time of the day in winter.

Common Redpoll, Weaselhead, January 8, 2017.

Common Redpoll, Weaselhead, January 8, 2017.

Common Redpoll, Weaselhead, January 21, 2017.

Another of our visiting winter finches, redpolls (common and Hoary) are here in small numbers this winter. They are easy to find in the Weaselhead as they also go to the feeders.

Black-capped Chickadee, Weaselhead, January 8, 2017.

Black-capped Chickadees are one of the most common songbirds in the Weaselhead year-round. You can also find Boreal Chickadees and occasionally Mountain Chickadees there.

Downy Woodpecker, Weaselhead, January 21, 2017.

Hairy Woodpecker, male, Weaselhead, January 21, 2017.

Other resident woodpeckers are the Pileated Woodpecker and Northern Flicker (Flickers are migratory but we have some here year-round). In winter you can sometimes find Black-backed and American Three-toed Woodpeckers as well.

Blue Jay, Weaselhead, December 6, 2015.

Dark-eyed Junco (Oregon subspecies), Weaselhead, December 6, 2015.

These sparrows are more commonly seen in the winter, and it is far more common to see the Slate-colored subspecies of Dark-eyed Junco.

Pine Siskin, Weaselhead, February 28, 2016.

Siskins are erratic in their movements and there are very few in the city right now. When there are big flocks around you will find them in the Weaselhead.

White-throated Sparrow, Weaselhead, December 6, 2015.

White-throated Sparrows are common breeders in the Weaselhead and you can hear them singing loudly there in the spring. Usually a few overwinter in Calgary, but I haven’t heard of any in the Weaselhead this winter.

American Tree Sparrow, Weaselhead, February 28, 2016.

Tree Sparrows pass through on migration but we often have some overwinter here. They will come to seeds under the feeders in the Weaselhead. Again, I haven’t heard of any this winter.

And now for a few mammals.

Coyote, Weaselhead, January 21, 2017.

Meadow Vole, Weaselhead, February 28, 2016.

Meadow Vole, Weaselhead, January 28, 2017.

I seem to see more Meadow Voles in the Weaselhead than anywhere else. In the winter look for them scurrying under feeders to quickly grab a seed. They are the preferred prey for Northern Pygmy-Owls.

Bobcat, Weaselhead, December 13, 2015.

Bobcats are seen more often in the Weaselhead than anywhere else in the city. To see more photos of this one and the rest of its family, see this post.

The Weaselhead is also one of the best places in the city to see Snowshoe Hares and, in the summer, Least Chipmunks. Red Squirrels are also common, and it is one of the few places in the city where you can reliably find Northern Flying Squirrels.

Furry Friday: Muskrat

Tony LePrieur photographed this Muskrat in the Weaselhead Nature Area on November 20, 2016. Muskrats are semi-aquatic rodents related to voles and lemmings. They feed mostly on aquatic vegetation such as cattails. They are active all year and can be found in the winter in Calgary along the rivers, and around lakes and ponds. They are well adapted for the cold and for swimming under the ice.

Sunday Showcase: Autumn in Calgary’s Parks

Posted by Bob Lefebvre

Catching up with some great autumn photos of Calgary Birds and Mammals, taken by Tony LePrieur from September 25 to October 16, 2016. The locations were the Inglewood Bird Sanctuary, Carburn Park, Fish Creek Provincial Park, and the Weaselhead Nature Area.

unnamed

Boreal Chickadee, Bebo Grove, FCPP, September 25, 2016. The bird has no tail. Birds don’t molt all their tail feathers at once, so this indicates it probably survived an attack of some kind.

unnamed-1

Great Horned Owl, Bebo Grove, FCPP, September 25, 2016. These resident owls are fairly common it the city. Pairs will be spending the days resting on their winter roosts now, and by February (or sometimes even January) they will be on their nests, incubating eggs.

image1

Great Blue Heron, Inglewood Bird Sanctuary, October 16, 2016. The herons have usually all migrated by mid-October, but a few may stay later.

image2

Harris’s Sparrow, seen at the south end of the big bridge over the Elbow River in the Weaselhead on October 16, 2016. The bird was seen for at least a week, from October 16 to October 25. These Sparrows mostly migrate well east of Calgary and are a bit of a rarity here. They sometimes overwinter, so it is worth looking for.

image3

American Tree Sparrow. These arctic breeders are passing through here now and some overwinter here.

image5

Dark-eyed Junco. These sparrows are pretty common here in the winter and can be seen in residential areas right now, often feeding on the ground under bird feeders.

image6

American Robin bathing.

image61

American Robin. They passed through here on migration in huge numbers a few weeks ago, but there are always quite a few that overwinter here, mostly in the river valleys.

image7

Northern Flicker (male). A migratory woodpecker, but again there are always lots in Calgary in the winter – either some local breeders that overwinter, or birds that bred farther north and migrated this far. They will readily come to suet and nut feeders.

image8

Downy Woodpecker (male). A year-round resident that also will come to feeders.

image10

Coyote.

image1

Black-backed Woodpecker. A bit of a rarity in the city, they are occasionally seen in the west end of Fish Creek Park, from Bebo Grove to Shannon Terrace. This one was photographed there on October 23, 2016.

image2

Pileated Woodpecker (male). Another resident woodpecker.

image3

Rough-legged Hawk. This is the common buteo in our region in the winter. They have arrived in good numbers from their northern breeding grounds. Most commonly seen outside the city, especially west of the city.

image4

Black-capped Chickadee. Year-round resident.

image5

Muskrat. They are active all winter in open water.

image6

Mule Deer buck.
