Monitoring a Flicker nest

Posted by Matthew Sim

As spring approaches once again, I like to reminisce about the previous year and all of its most exciting moments.

For the past several years, flickers have nested in my neighbor’s tree. I had never really observed this nest closely before; however, last year, I did just that.  Flickers usually excavate nest holes in dead or dying tree trunks or large branches. These nest holes are most often found at 6-15 feet off the ground and will often be reused.  By late May/ early June in Calgary most flickers have laid their 5-8 white eggs. I started to notice that the flickers were more active around the nest in early June and it is my belief that on around the 3rd or 4th of June, “my” pair laid their eggs.

This is the nest hole with the female looking out on June 10. The flickers had been in and out of the hole since late May

    Incubation of the eggs ranges from 14-16 days and I had been closely following all the bird’s actions in attempt to discover when the eggs would hatch. On June 24, I heard the first sounds coming from the hole. The flickers had been born! I think that we can assume that there is a possibility that the young flickers were born a day or two earlier and I had not heard them until then.

If you compare this shot with the photo above, you can see that the leaves around the hole grew a lot as the summer progessed, adding even more security and privacy to the flicker residence.

The first visible evidence of the young flickers was the clean-up crew. As all parents can attest to, there is a lot of cleaning up involved with kids.  The adult flickers, both male (pictured in photo above) and female, had to work constantly to ensure that their young were well-fed, safe from predators and, perhaps most importantly, in a clean home.

July 1st came around and I had still not seen the young flickers, though I had definitely heard them. Each and every day they were getting louder and louder and soon I could hear them from across the alley, in my yard, maybe 35 feet away. The young flickers cry is often described as a hissing noise and is uttered for two weeks, day and night, growing stronger as the birds grow older.  I was not worried about not having seen the flickers yet as their eyes do not open until they are ten days old, so  wouldn’t be seeing them until then. July 3, I was up in Banff, where I happened upon a flicker nest with two young already poking their heads out of their hole. At that point, I couldn’t help but wonder how my flickers were doing.

July 5th, marked a special day for my monitoring project. That day, I got my first glimpse of the young flickers. I took my first photos of the young flickers on July 9th, and they were looking healthy and fit; all 3 of them!

But that’s where it went all wrong. The nest holes of flickers (and often of many other species of birds) are the scenes of very fierce battles. Three young birds with very sharp bills, duking it out for supremacy and the right to remain looking out of the nest hole, therefore receiving the most food. The stronger birds almost invariably end up on top, and maintain their authority by jabbing the others with vicious pecks of their beak. The opening is only big enough for two heads and the third one gets pushed to the bottom. There, the young flicker receives very little food and consequently, it perishes. July 9th, I took the photo above, showing 3 young flickers. By the next day, July 10th, I was only seeing 2 young flickers.

Disappointed though I was, I realized that sometimes, this is the way nature must work. I continued to watch the flickers for several days, amazed at the rate at which they grew. After about 4 weeks, the flickers would fledge and would begin to leave the nest; my flickers started appearing out of the nest around July 16th. The two young birds started hopping about and practicing flying, getting ready for the day when they would leave the nest altogether.

Than one day, I did not see the flickers. Nor did I see them the next day. Or the day after that. It would seem that the two young flickers that I had watched for a nearly a month had successfully fledged. I don’t think I ever saw these two again, though I was seeing flickers in the neighborhood, which might just have been one of the young. From time to time, I did hear the distant call of several Northern Flickers and I couldn’t help but wonder if it was the fledgelings, calling away.

 

Bebo Grove and Shannon Terrace – Fish Creek Park’s quieter, calmer west side

Posted by Dan Arndt

This week the Friends of Fish Creek course was touring through Bebo Grove, over to Shannon Terrace, then back again. It’s approximately a 5 km route, return, and throughout the week, some great new birds were seen, such as the American Three-toed Woodpecker, Boreal Chickadees, and a fairly good number of White-winged Crossbills.

Bebo Grove to Shannon Terrace Route

I was most excited for the American Three-toed Woodpecker, since that would be a new bird for me for the year, and probably a more satisfying sighting than my original sighting of it, which ended up being back at my computer scanning through my photos and later realizing that yes, that little black and yellow lump on the trunk of the tree was, in fact, the American Three-toed Woodpecker I’d been looking for.

Here’s that photo, for reference, taken back in August 2010 at Brown-Lowery Provincial Park.

Unfortunately, both Saturday and Sunday groups missed out on good sightings of the woodpecker, but at least on Sunday we got to hear it calling amongst the trees, and a brief flyover allowed at least one confident ID, but certainly no photo opportunities. Flyovers of uncommon birds seemed the rule of the day, as we also had a Grey Jay towards Shannon Terrace, which, to my understanding, hadn’t been seen in the park for a number of years.

The good side is that we did get great views of Hairy and Downy Woodpeckers, Red-breasted Nuthatches, the amazingly adorable Boreal Chickadee, and a few Townsend’s Solitaires.

I was particularly happy with this shot of the Common Raven, which are always hard to shoot against a light sky, which tends to wash out their features. Thankfully, this bird decided to perch in the foliage, allowing much better views of its somewhat iridescent plumage.

Add to that the many great angles we were given of the White-winged Crossbills, such as this one, detailing the presence of the crossed-bill for which it gets its name.

The gender of the Red-breasted Nuthatch can be identified by the color of the crown. The male, seen below, has a jet black crown.

The female, on the other hand, has a grey crown. Even without the two of them together, just a quick comparison of the color of the eye line and the crown can show that telltale difference.

Both the male Downy and Hairy Woodpecker can also be identified by the bright red patch on the back of their heads, while the female lacks the red patch.

I was quite impressed at this little Townsend’s Solitaire on Saturday. While preening, it stretched out its wings again and again, showing off the thick yellow bar in the primary flight feathers of the wing. Unless it’s displaying like this, that yellow bar is almost invisible, and in some individuals, nearly absent.

Wednesday Wings: Bathing Merlin

If you’ve taken any pictures of interesting birds in the Calgary region, you can share them with us by emailing birdscalgary@gmail.com and we may post them on the blog.

Dave Arnold took these great shots of a Merlin having his Sunday bath on the edge of the Bow River.  Thanks for sharing, Dave!

Ian Chatt also witnessed this and got these three photos:

Join The Great Backyard Bird Count

From February 17-20, take part in a free, family-friendly, educational activity that is loads of fun and supports bird conservation! Each year, tens of thousands of Canadians and Americans take part in the Great Backyard Bird Count (GBBC), counting birds wherever they happen to be. The possibilities are endless!

The GBBC is a great way for people of all ages and levels of birding experience to learn more about local bird species. It’s the perfect opportunity to connect with nature, from your living room window or by hiking a local trail. Count on your own or as part of a group of family, friends, or classmates. The GBBC is also an ideal way for more experienced birders to introduce others to the wonderful world of birding.

Explore the species seen in your community or province using maps and charts on the Canadian GBBC website, where you can also find out how to take part in the community challenge and view Canadian highlights. Make the birds in your neighbourhood count as part of the big picture in continental bird conservation. You don’t need to pre-register, just start counting and submit your results!

It’s as easy as 1,2,3!

1. Plan to count birds for at least 15 minutes on one or more days of the count. You can count for longer than that if you wish! Count birds in as many places and on as many days as you like—one day, two days, or all four days. Submit a separate checklist for each new day. You can also submit more than one checklist per day if you count in other locations on that day.

2. Count the greatest number of individuals of each species that you see together at any one time.  

3. When you’re finished, enter your results through our web page. You’ll see a button marked “Enter Your Checklists!” on the website home page beginning on the first day of the count. It will remain active until the deadline for data submission.

A grey day at Beaverdam Flats

posted by Dan Arndt

 

Sometimes it doesn’t seem like there are enough hours in a weekend to get a proper update in! It certainly doesn’t help when it seems like such a quiet day with very little bird activity.

Sunday morning walking through Beaver Dam Flats seemed eerily quiet. Despite the sheer numbers of Canada Geese, Mallards, and Common Goldeneye on the Bow River, once we steered away from the eastern bank and into the primarily barren deciduous wooded area, the bird activity seemed to completely quiet down. We were treated to a good number of low flyovers by both juvenile, immature, and adult Bald Eagles, and a great sight of a Common Merganser gulping down an extremely large fish, the highlight of the morning were the Townsend’s Solitaires along the eastern slope of the valley. We counted three separate individuals, one in particular allowed us an extremely close view.

Enjoy the pictures, and I’ll be back to my regular wordy posts next Monday!

Wednesday Wings: Tree Geese

A blast of summer among the snowy owls and redpolls! Rob English has sent us some Canada Geese photos that are not your usual view of these birds. He says “This was new to me as I’d seen them in poplars but never  fir trees.  They were scrapping over some old magpie nest they wanted for a perch and were really causing a commotion until the one drove the other off and it went to another fir tree about 25 yards away. I took these shots in Carburn Park last May.”
