Watch the Ospreys and Peregrines!

Posted by Bob Lefebvre

The weather may still be a little closer to winter conditions than to spring, but now the Ospreys and the Peregrine Falcons are back, and you can watch them at their nests from the comfort of your home.

The first Peregrine returned to the University of Calgary campus on March 31, 2014. You can watch a live feed from the nest camera here: U of C Falcons .

The first Osprey was reported at the platform by the Calgary Zoo on April 17. You can see the live feed here: Zoo Osprey .

So far there hasn’t been much activity at the nests, but once the females are on the eggs it’s a lot of fun to check regularly and see the feeding activity, the hatching of the eggs, and the growth of the chicks.

There will be a link to these cameras on the right-hand sidebar of the blog throughout the nesting season so you can check on them regularly.

Sunday Showcase: Goshawk Feeding

Karen and Roger Bolton had the unusual experience of seeing a Northern Goshawk eat a Blue Jay in their yard in Glamorgan, SW Calgary, on December 7, 2013. These powerful raptors are scarce in winter in the Calgary area. They feed on game birds like pheasants and partridge; rabbits, and rodents, as well as songbirds. (Click on the photos to enlarge them.)

Refinery Park and Lower Beaverdam Flats – An Eagle’s Paradise

Posted by Dan Arndt

Well… maybe paradise is overselling it a bit, but we did a good show from a few Bald Eagles on our outing this past Sunday! Three days this week the outings had been cancelled due to extreme weather and extreme cold. Unheard of for the hardiest of our leaders, but everyone has their limits! Unfortunately, the weather early this morning kept most of our participants away, so we headed off with three leaders and one hardy participant into the cold and the wind.

What started off as a cold, blustery and grey day turned into some amazing blue skies, much warmer weather than we’ve seen all week, and some great opportunities to get some action shots. Needless to say though, it took a little bit for everyone to get going, including some of the first groups of birds we saw. This backwater along the Bow River was completely full of mostly Canada Geese and a few Mallards for good measure.

Even the Bald Eagles looked completely unimpressed in the cold and the wind. The expressions of utter contempt for both us, and the hundred or so waterfowl just below them in the water, have led me to nickname these two as Hekyll and Jekyll.

As we turned back to follow the river bank southward, things started to pick up. The sun was making a serious attempt to break through the meager cloud cover to the south and east, and some of the birds began to show a few more signs of life. A third immature Bald Eagle was being chased (but not quite harassed) by the Common Raven keeping a keen eye on it from below.

As the wind picked up a little, it caused the birds to begin to fly up-river, allowing some half-decent flight shots. Along with the wind picking up, the sun finally began to break through, and provided some great light for the remainder of our walk. First up, a male and female Common Goldeneye, flying by within a few minutes of each other.

A moment later, a female Barrow’s Goldeneye flew by, and a male of the same species broke away from the Canada Geese at the far shore and made his way into the middle of the river shortly after.

This group of Buffleheads touched down in the water about halfway into the river, showing off their bubble-gum pink legs. That’s one lucky male Bufflehead getting the pick of mates this winter!

And last but not least, this male Common Merganser flew by quite close, showing off his bright red bill and a hint of green in the head as the sun began to shine.

We continued south along the river without seeing too much else of note, but shortly after we turned back on one of the inner pathways, this subadult Bald Eagle flew by behind us and alighted in a tree, closely tailed by a flock of scavenging Common Ravens, looking for whatever scraps they could manage to steal from the wary bird of prey.

A couple of Black-billed Magpies even came in for a piece of the action. Or maybe just a piece of the Mallard.

If there’s one thing I love most about winter birding in Calgary, I’d have to say that above the Snowy Owls, above the winter finches, and even above the odd vagrants we’re gifted with every couple of years, I certainly love seeing the influx of Bald Eagles the most. One of the groups this week in Beaverdam Flats recorded no less than ten (yes, 10) Bald Eagles in a single outing. While it’s not quite the same as the incredible numbers seen on both east and west coasts in the height of the season, it’s still an incredible treat to us landlocked city-slickers to have such unrestricted access to these regal and immensely powerful raptors.

That brings us to the end of our Autumn Birding Course for 2013. We’ll be picking back up in January again, but between now and then I’ll be sure to keep you all updated on the Christmas Bird Counts I’m taking part in, as well as the various travels that I happen to find myself on this holiday season!

Thanks again for reading, and good birding!

Wednesday Wings: Ospreys

Ospreys have returned and have started to nest on platforms across the city. When this Osprey arrived at the platform at MacLeod Trail and Highway 22x on April 24, he first had to evict a pair of Canada Geese who had thoughts of nesting there too. Photos by Joe Harley.

Joe also got some great shots of an Osprey with a fish south of Carburn Park. This is one of the pair that is nesting at the Lafarge platform along MacLeod Trail just south of Southland Park.

Zoo Ospreys are Back – Watch Live

The Ospreys are back on the nesting platform at the Calgary Zoo. So far there are just a few sticks on the platform, so if you tune in to the live Enmax web cam, over the next few weeks you can watch them build the nest, lay eggs, and raise their young until they fledge.

Below is a link to the web cam. We will also have a link on the right sidebar of our Home Page throughout the nesting season. Check out the U of C Peregrine Falcon nest cam too!

Go to the live web Osprey nest cam here.

Peregrine Falcons at U of C

Since at least 1995, Peregrine Falcons have nested on Craigie Hall at the University of Calgary. For the past few years, there has been a live nest cam so that we can watch the falcons at the nest, and see the young falcons hatch and fledge.

The first returning Peregrine was sighted on March 25 this year, and by April 9 the pair was ready to nest. The first egg was laid on April 16. We will have a link to the nest cam on the sidebar of our Birds Calgary home page throughout the breeding season.

Sunday Showcase: Bald Eagle Fledgling

Rob English got these photos of a recently fledged Bald Eagle in Carburn Park in early August 2012.  The bird had just recently left the nest across the river.
