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.

 

Brand New Downies

We recently had a couple of very cute visitors to the yard – a couple of hatch year downy woodpeckers. They seemed to be eagerly checking out their surroundings, much like excited youngsters of any species in a new environment.  They were so small that when the first one landed on the tree, I thought for a minute it was a Brown-creeper.

The Woodpecker Tree

While on my latest bike ride into Fish Creek Provincial Park, I came across one very special tree. I have started calling it: The Woodpecker Tree. Standing proud and tall on the banks of the creek, this poplar tree seemed to be a gathering place for woodpecker food. I abruptly stopped on the dirt path I was riding on because I had heard a Hairy Woodpecker calling. I approached the tree for closer inspection and I was surprised to see 2 Downy Woodpeckers and a large female Hairy Woodpecker. Much to my surprise I heard another Downy Woodpecker calling high up in the tree and I looked up to see a male Downy Woodpecker and a White-breasted Nuthatch. I then heard a tapping coming from the opposite side of the tree and found it to be a male Hairy Woodpecker tapping away. Eventually, my final count of woodpeckers came up to 3 Hairy Woodpeckers, 4 Downy Woodpeckers and the lone White-breasted Nuthatch.

This tree obviously fulfilled the nourishment needs for 7 woodpeckers and a nuthatch. As I continued to watch all these birds, I saw them eating insects, tapping at fungal growths on the tree and investigating sap.

After a dozen of  minutes or so, the woodpeckers started to spread out into the surrounding area to hunt down more food. Yet some of the birds, stayed on the woodpecker tree, clearly enjoying the abundance of good food.

Now, I can’t help but wonder if this is a regular occurrence at this tree, or was it a one-time event?
