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.

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.

Revering a Raptor

Oct28

From the day that I first laid eyes on the species, gliding on broad wings over a coniferous forest in the Rocky mountains of Alberta, I have always looked with awe at it, astounded by its sheer magnificence. Many people have soft spots for raptors. I have a soft spot for one in particular: the Northern Goshawk.

I first saw a goshawk just over a year ago. It was early October 2010, and I had signed up for the Mount Lorette Golden Eagle field trip with Nature Calgary. I went out on my own to explore the area right around the location of the watch, and, while out on the path, witnessed an adult goshawk rise up from the spruce trees and circle away. From that moment on I was always looking for goshawks; every chance I got, I would go searching for them.

Rising up out of the forest; my first views of a Northern Goshawk

Several days later, on a biking trip to Fish Creek Provincial Park, I came across an adult Goshawk perched high up in a poplar, sitting and gazing at the world around him. I stood and watched this magnificent raptor for more than half an hour, pointing the bird out to anybody who came near. Many of these were joggers or were merely walking their dogs. They took little interest in this bird, that is somewhat tricky to spot in the city of Calgary. I was rewarded though by the few who did pause to look up at the goshawk and comment on his size.

“What did you say it was called?”

“A Northern Goshawk”, I would reply eagerly, ” it’s somewhat unusual here in Calgary.”

“Really? Wow! Look at how big he his!” After staring up at him for several more seconds, they would smile and move on. Hopefully the Goshawk had made an impression on them though.

While I watched this large, strong accipter (agile, forest dwelling hawks with short rounded wings and long tails) it scratched its head withs its talon, giving me glimpses of those wicked sharp utensils it uses to tear apart its prey. Eventually, it lifted off and disappeared amongst the trees.

Goshawks are among the largest, strongest and most audacious of the hawks of North America. In November 2010, a little over a month since I first observed this species, I got an excellent opportunity to view this audacity. I was riding my bike home from Fish Creek and was running slightly late. I looked down for a moment as I pulled onto a dirt path going around a storm water pond, and, when I looked up again, there, sitting merely yards away from me in a small tree no taller than 10 feet, was an adult goshawk. They now seemed to be everywhere I went! I slammed on the brakes as hard as I could and screeched to a stop, panting breathlessly. Pulling out my camera, I marveled at how close this bird had let me get. I stood watching him, he stood watching me, this went on for several minutes before he abruptly flew away.

Taken with a 200mm lens and no crop; I could see every detail in the feathers

Instead of leaving altogether though, the goshawk started hovering over a field, pulled up, started hovering again and then pulled up once more. Then, with a sharp turn, he came whizzing right at me and flew by me at a distance of about 4 feet! The raptor was so close that my lens couldn’t focus on it!

These incredibly neat personal experiences combined with an amazingly beautiful species, have come to make me love the Northern Goshawk.

Sunday Showcase: Young Swainson’s Hawk

Oct23

Rob English was fortunate enough to capture these stunning shots of a young Swainson’s hawk hunting grasshoppers. He took them in Hulls’ Wood, Fish Creek Park in early September. He says the bird hung around the area for about three days, and showed no fear. His wife named him “Mr. Personality.” Thanks so much for sharing these Rob! Click to enlarge.
