A Merlin in Our Midst

By Cathy Warwick

Introducing Catherine Warwick – Cathy is a local birder who has been living in Calgary since 1997. She has been birding seriously for about fifteen years. She enjoys hiking, writing, and tavelling. Cathy has been writing an article about birds for the Lakeview News and Views newsletter for the past year or so. Birds Calgary will be featuring her new articles here monthly, and reposting some older ones too. Welcome aboard, Cathy!

A Merlin in our Midst

You may have seen a Merlin swoop past and thought – “That is one fast Robin.” This small but fierce falcon is a very fast flier, so fast it’s usually a blur. So you can be forgiven for mistaking it for a Robin that has gone to the gym regularly and lost its big red belly, as well as gaining some wing definition. What unmistakably identifies it as a Merlin, however, is the call it is making as it swoops around. They make a loud, “Klee-klee-kleeee” sound in flight that evokes the wilderness. This call is drawn out and falls in volume as it happens. In addition to the sound you can look for a smart-looking striped tail and sharp wings should it happen to land and give you an eyeful.

In Calgary I have seen them at the tops of trees, speeding around and calling out noisily. Sometimes they will have Magpies and Crows chasing them. This drama in the birding world is understandable when you find out that Merlins don’t build their own nest, they essentially take over the nest of a Magpie, Crow or another raptor. How lazy! No wonder the Crows and Magpies try to chase them away. Merlins have been known to lay their eggs right on top of a domed Magpie nest. The mother Magpie would be moving her brood in a hurry. Pack your bags kids, a killer has moved upstairs!

The Merlin is one of the smallest raptors in Alberta and is pretty darn cute. They must be terrifying to songbirds however, swooping in and picking off the slowest. Songbirds are its main source of food. Consider this: A Sparrow weighs about one ounce, as much as a pencil, thus a Merlin is estimated to eat about 900 a year. It’s a lot of work! They need all their energy for their fancy aerodynamics, and can’t waste it on such mundane things as building a nest. Most of their kills happen in the air, probably because they are such terrific fliers. It’s no wonder little birds seem nervous all the time, one minute you’re flying around and the next you are snatched up by a pint-sized raptor. Merlins eat pigeons too, which are basically the same size as them, talk about fierce!

It’s possible the ones in Calgary will over winter here, city Merlins often stay instead of heading to South America like they are supposed to. Merlins just started to be city dwellers as recently as 1960, possibly at the same time as House Sparrows became plentiful. Merlins have a long history with people anyway, in medieval times they were trained as hunting falcons. They were called ‘Lady hawks’ because women favoured them. Is it because our puny lady arms would crumple under a big falcon? No, surely it’s because a Merlin’s charm is as large as they are small. 

The best birding app out there is named after them in fact. If you ever want to identify a bird by sound just get the Merlin Bird ID app from Cornell Labs. It’s a miracle to hold up a phone to a singing bird and get an identification right away. It makes birding a lot easier.

Seeing a Merlin is the birding equivalent of a bolt of lightning, streaking around our residential streets.

Birds of Carburn Park in March

Posted by Bob Lefebvre

Carburn Park has been a good place to bird all winter, and it is one the best places to visit in the spring as well. Tony LePrieur photographed these birds in the first half of March, as we began to transition to spring birding. All photos by Tony LePrieur.

Merlin

Great Horned Owl

Great Horned Owl. These birds are early nesters, and are on the nest by mid-February. Disturbingly, there have not yet been any reports of nesting Great Horned Owls in the city. It appears that the local Meadow Vole population has undergone one of its periodic crashes, and the owls may not have enough food to raise a brood. If they don’t start soon there won’t be time to teach the young how to hunt before next winter, so they may forego breeding altogether this year.

Bohemian Waxwing

Bohemian Waxwing. They will soon be leaving the city for higher elevations or more northerly breeding locations. Most are gone by mid-April, with occasional sightings into the first week of May.

Northern Flicker

Northern Flicker. This male may be starting a nest cavity soon. They have been very vocally claiming their territories in the past three weeks or so (and drumming too). The red malar mark or mustache indicates a male. Females lack a mark there. This bird is an intergrade between the two subspecies, the Red-shafted which has a red malar mark and lacks a mark on the nape, and the Yellow-shafted which has a black malar mark and a red mark on the nape. The majority of flickers in the Calgary area are intergrades.

Downy Woodpecker

Downy Woodpecker (male). Like the Northern Flickers, males and females of this species are paired up and are beginning nesting behavior.

Northern Shoveler

Northern Shoveler (male). This bird, and the female below, was not reported this winter, so is likely an early migrant. An early Northern Pintail has also been reported on the river.

The Friends of Fish Creek bird the Irrigation Canal

Posted by Dan Arndt

The Western Headworks Canal (known to many of us simply as the Calgary Irrigation Canal, or Bow River Irrigation Canal) is an amazing area to bird any time from early spring all the way through to the beginning of autumn. The canal itself provides foraging and feeding opportunities to all varieties of dabbling ducks throughout the breeding season, while the established trees and shrubs along the edge of the canal are home to no end of songbird species throughout the year.

There is a very special time of year though, just after the first of October, when the Western Irrigation District stops drawing water from the Bow River and allows the canal to drain for the winter. It is at this time that the canal becomes prime feeding habitat for a few more exotic species. Unusual and rare gull species are often found among the flocking Ring-billed Gulls, late migrating shorebirds feed along the extensive mudflats, and the tail end of songbird migration can often bring exciting birds such as Rusty Blackbirds and the occasional Harris’ Sparrow along the edges of the canal. All of this excitement is over far too quickly for some as the water levels rapidly deplete over the course of the first two weeks following the drainage.

According to the Western Irrigation District website, “the Western Irrigation District provides irrigation water to over 400 farms and 96,000 acres of land, and supplies municipal water to over 12,000 people in four different communities through 1,200 km of canals and pipelines.  Like other irrigation districts in Alberta, the WID operates under the rules and procedures of the Irrigation Districts Act.  The WID is headquartered in Strathmore, Alberta, which is approximately 40 kilometers east of Calgary.”

On October 4th, I joined the Friends of Fish Creek to walk the canal a few days after it had begun draining. For one reason or another, this year seemed to have fewer birds than I remember in the past, and the water seemed much lower this early on than previously. That said, the walk started off on a high note while I watched this Northern Flicker feeding on berries in a shrub while I waited for the group.

Almost immediately upon reaching the edge of the canal, we began seeing some of the diverse assemblage of waterfowl that feed along the canal. The most common of course was the Mallard, with almost all of the males having returned to their brilliant green-headed breeding plumage.

A lone female American Wigeon dabbled in the shallow water, barely lifting her head to check us out as we walked by.

A little further on, a pair of female Northern Shoveler floated by, followed closely by a pair of female Green-winged Teal.

The highlight of the waterfowl though are always the Wood Ducks. A fair number of them were found feeding along the canal early in the walk. As we continued down the canal, something spooked them and they flew up the canal and our of sight. These birds are likely from the same stock found at the Inglewood Bird Sanctuary, where they are known to breed each year.

It’s always a bit of a surprise to see what shorebirds we can find down along the canal. It’s one of the best places to get good, close looks at Greater Yellowlegs, often in large numbers.

Less often though do we get Wilson’s Snipe. This year there seemed to be more than a few feeding along the canal.

It was a little later on that we got a good look at what may have flushed the Wood Ducks earlier in the day. This female Merlin swooped in and perched in the trees right above us for a few moments before flying on and continuing her hunt.

There is one major benefit to the large numbers of Rock Pigeons that take residence in our urban centers here in southern Alberta, but it’s never a pretty sight to see. They make a great meal for any number of hawks, falcons, eagles and owls. Every once in a while though, one of these raptors gets chased off a fresh kill by a family of corvids. It is quite possible that this was a kill stolen from our female Merlin above, or from the Sharp-shinned Hawk that as giving us continuous fly-bys all morning.

While we kept our ears and eyes sharply focused on the shrubs nearby, and our alertness really paid off. We heard a handful of American Tree Sparrows, saw few Dark-eyed Juncos, and caught decent looks at what are likely to be our last Yellow-rumped Warblers for the year.

It always pays off to check out the gulls down on the canal though. As we walked the canal, we found hundreds of Ring-billed Gulls feeding in the shallow water.

One of our sharp-eyed participants pointed out this little Mew Gull all by itself. They feed a little bit differently than Ring-billed Gulls tend to, but the real differences are the major field marks. You might note the plain yellow bill, smaller, rounded head, and overall “softer” features than the Ring-billed Gulls above.

Mid-November in Pearce Estate Park – But I LOVE identifying gulls!

Posted by Dan Arndt

… said no one ever. I kid, I kid. There are a few die-hard larophiles (from the Latin larus, meaning gull, and the Greek philos, meaning to have a strong affinity for, to love, AKA people with WAY too much time on their hands) out there who spend dozens of hours each year picking through flocks of Ring-billed and California Gulls to pick out a rarity, but I certainly don’t have the patience for that. Some people draw the line at flycatchers, others at shorebirds, specifically peeps, but me, I draw mine at gulls.

Don’t get me wrong. Gulls are wonderful in their own way, but spending hours picking through hundreds of them for something a slightly lighter or darker shade of grey is not my idea of a fun time.

November 15, 2015

November 15, 2015

As fall begins to cool and the ponds and creeks begins to ice over, there are a number of large gravel bars along the Bow River where gulls begin to accumulate in numbers. Our reason for visiting this park were specifically because a couple of uncommon gulls had been reported here resting among the dozens of Ring-billed Gulls. The three species we were here to find were the Thayer’s Gull, Mew Gull, and Lesser Black-backed Gull. We did come up with the first two, but our Sunday group was a few days too late, as the Lesser Black-backed Gull hadn’t been seen since Wednesday.

This photo was taken through my Vortex Viper spotting scope using a PhoneSkope adapter and my Samsung Galaxy S5 built in camera. Can you spot the Mew Gull? I couldn’t for a good half hour. I’ve seen many Mew Gulls in British Columbia, usually associating with California Gulls but never among Ring-billed Gulls. I was expecting to find a gull with a bit of a lighter mantle, rather than darker. The Mew Gull is just a little bit to the left of center, resting with its bill hidden.

[exif id=”15035″]

Here’s a shot of the bird zoomed in a bit closer with its bill out. It’s now obvious that the bird is a shade or two darker than the Ring-billed Gulls on the mantle, and has a tiny, unmarked yellow bill. Again, the Mew Gull is the one just a little bit left of center with the round head and dark eye. A tough spot, to be sure!

We did get a good look at many of the other gulls, including this immature Herring Gull sitting on the remains of the old weir. It was particularly noticeable due to its large size, pink legs, and overall dark plumage, but that bill shape was also a good indicator!

Ring-billed Gulls

[exif id=”15032″]

And of course, here are a couple of the ever-present Ring-billed Gulls on the water. The low angle sunlight and the perfectly clear morning sky made it a bit tough to expose correctly, but it’ll be one of the last shots I would get of any gulls until late February or early March next year. It’s surprising every year how they just seem to totally disappear around the end of November and by the time the Christmas Bird Count rolls around, they’re almost a distant memory!

Double-crested Cormorant

Another great sighting that day was this immature Double-crested Cormorant, who gave us a fly-by and perched in a tree across the river shortly after. This would be the latest sighting of this bird I’ve ever had, and from other reports, it is apparently sticking around a bit further downstream!

We headed a little west where earlier groups in the week had found a some Bald Eagles, and we certainly weren’t disappointed. At first, the immature eagle flew in to check us out, and a few minutes later the adult flew in and flushed the younger bird off. When I had visited the park earlier in the week, I noted that the gulls seemed to have a sixth sense for approaching eagles, flushing easily a full minute before they came into view from my angle. When you’re a gull you have to be on alert for predators, especially ones that can so easily take you out like a Bald Eagle can!

While we were watching the Bald Eagles, we spotted this male Merlin as he flew in with what appears to be a House Sparrow in his talons. Because this part of the park is adjacent to a large residential area, it wasn’t too surprising to hear and see the House Sparrows, it was a bit of a surprise to see this guy!

We walked all the way back to the east end of the park where we watched this girl fly in and perch above us. I suspect she was watching the ground for voles, as she sat there staring at the ground for quite some time while we watched.

Black-billed Magpie

As we watched the Merlin, a couple of Black-billed Magpies flew in and began foraging on the ground, but also keeping a sharp eye on her. They spent a good amount of time keeping an eye on us as well.

Around this time, the traffic on the pathway started to pick up due to a running race, so we headed back in to the inside of the park.

One of the birds we had heard flitting about overhead for most of the morning was a single Common Redpoll. Towards the end of our walk that morning it popped up into this shrub and perched for a few minutes, giving everyone good (but distant) looks at it. While this season is a pretty good one for these birds, I still haven’t had a chance to see one up close and personal.

On our way out of the park, we walked past a couple Mallards in the floating fen ponds near the entrance, showing off once again their bright green breeding plumage, curly black tail feathers, and complex browns and grays. It’s nice to see them back in full colors after a few months of seeing them in eclipse plumage!

And that’s it for another week! Have a great week, and good birding!

Bebo Grove and the arrival of winter birds

Posted by Dan Arndt

It certainly didn’t feel anything like fall on our last few outings with the Friends of Fish Creek. Aside from a little bit of snow sticking around, and a bit of a brisk start, we’ve had incredible luck with our fall weather here in Calgary, or at least on our Sunday walks!

Bebo Grove is one of our most anticipated outings in the fall for a number of reasons, all of which are owls. Northern Pygmy-Owls were the star last fall and winter, and there’s always the chance of finding Great Gray Owls, Barred Owls, and of course Great Horned Owls. It is also relatively dense spruce forest, which draws in both species of crossbill, Pine Grosbeaks, and even Common and Hoary Redpolls.

While we didn’t have much luck in the redpoll department, we did have a good variety of everything else, and even had a couple bonus raptors show up!

Bebo Grove - November 1, 2015

Bebo Grove – November 1, 2015

For the third (maybe fourth?) year in a row, the star of our show was Bob. Bob is a Red-breasted Nuthatch with a fairly prominent patch of leucism (read: white feathers) on his head. He’s the dominant bird in his little mixed flock of Black-capped and Boreal Chickadees, Red-breasted Nuthatches, and Brown Creepers, which is noticeable immediately when he is being fed. He flies in, right to the food, flushing every other bird nearby, and coming back time and time again to gather more for his numerous caches.

We searched for American Three-toed Woodpeckers, Black-backed Woodpeckers, and even Pileated Woodpeckers in the area surrounding the picnic tables, but came up almost entirely empty. We did find a Hairy Woodpecker a little bit to the west, but once we entered the next stand of spruce between Bebo Grove and Shannon Terrace, things really started getting busy!

We stopped shortly after to investigate the tops of the nearby spruce trees, as cones began raining down onto the pathway in front of us. Nearly a hundred White-winged Crossbills were filling the trees above us, calling, feeding, and flying about in a frenzy.

As we were walking through the dense spruce, we heard some agitated chattering of chickadees and nuthatches, as if they were harassing a predator of some sort. We searched around and as we came into a clearing to get close enough to investigate, a young Great Horned Owl flushed up from a spruce across the clearing, flying west and away. It definitely pays to check these things out, even if its only a rare occasion where you actually do stumble upon a prize like that! As we scanned the trees north of the clearing for where the owl went, we did spot this distant Sharp-shinned Hawk. It’s just too bad it didn’t stick around when we got just a little bit closer later on.

A little further to the west, we found yet another mixed flock, and had a few Boreal Chickadees, Black-capped Chickadees, Brown Creepers and still more Red-breasted Nuthatches feeding heavily in the trees, and a few even posing nicely for us.

Coming into the next clearing, we had a bit of a close encounter with a big Mule Deer buck. We actually found him first having a bit of a sparring match with a willow shrub, but as we walked by, he took notice of us and just had to show off his antlers.

We headed towards the barn at Shannon Terrace before turning back. It was a little more quiet to the west than we usually have it, but it wasn’t too much further along that we found out exactly why. This female Merlin was keeping a sharp eye on the ground below, especially one of the feeding stations, and looked quite interested in any little movement nearby.

So with that, we headed back to take a second look for Northern Pygmy-Owls, Barred Owls, and American Three-toed and Black-backed Woodpeckers, but came up (mostly) empty, so we followed the edge of the wetland back to where we had found Bob earlier in the day, but were alerted to the presence of yet another Great Horned Owl by the chattering and squawking of a pair of Blue Jays.

Wednesday Wings: Merlin with Rock Pigeon

Posted by Bob Lefebvre

I have often seen Merlins chasing Rock Pigeons, but it seems to be a very hard bird to catch. On April 10, 2015, near 19 Street NE and the Trans-Canada Highway, Chris Johnson got this excellent shot a Merlin with its Rock Pigeon prey.
