There has been a winter's worth of snow this December. Above is a photo of a spruce seedling I planted 5 summers ago. I took the picture on the 23rd of November. Below is an image from approximately the same location taken on the 28th of December. All you can see of the spruce seedling is one twig poking out of the snow.
I saw my first insect yesterday, some sort of flying insect, a midge perhaps. The temperature was hovering around zero and the ground is still snow covered yet the insects are stirring. The birds know spring is around the corner too. I saw my first red-wing blackbirds on the 12th staking out claims in the bushes across the road. I haven't seen a robin yet, perhaps the snow is still too deep. It will take quite some time to melt the snow pack this year. A couple of weeks ago on the 12th when the last warm spell attempted to make a dent in the snow banks, it formed a large puddle over the bike path.
More snow today. We have had quite a lot of snow this winter which makes a change from the last two winters. One unfortunate side effect of deep snow is that the white plastic spirals that protect the trees from the meadow voles aren't as effective. In the below photo you can see a meadow vole has almost completely girdled a maple tree just above where the plastic spiral stopped. A warm spell in January had given a hard crust to the snow, then a later snowfall gave the voles something to tunnel through at this new surface. This photograph was taken at the end of January when another warm spell revealed their pathways. Some of them were only market out by the dirt from their feces. In the photo below the dark specks of dirt on the snow around the trunk are feces from the meadow vole.
Not too far from this tree I spotted tracks that told a very clear story in my mind. In the first photo below you can see the tracks of a meadow vole as it was hopping over a fresh sprinkling of snow past a few grass stalks poking out of the snow. Suddenly its tracks stop at a place where there are a whole mess of confusing tracks. Looking more carefully in the second photo below there are a few specks of bright red. Somebody caught the poor guy and whoever caught it must have flown there. You can see what are clearly the mark of the bird's broad tail and the marks of its feet. About 10 feet from this spot in the third photograph are the marks of a large bird's tail as it brushed the snow. The story that comes to me is of a meadow vole scampering along in the dark over the fresh fallen snow when an owl perched 50m away in the bushes spots it. It launches itself and glides in low over the snow. It caught the vole before the little guy even knew it was there and dispatched him on the spot before taking off to feed at a more secure location. I would bet the bird was an owl as a vole is quite unlikely to be out in the open like that except at night, the most likely candidate being a Barred Owl as I know they are about because I saw one this winter in the Stoney Swamp.
As a bonus, here is a Youtube video of a meadow vole behaving quite strangely in broad daylight. This isn't my video but I saw a meadow vole behave like this several years ago on the berm. It just rested in broad daylight on top of the snow as I passed quite close by on my skis. I didn't have my camera with me that day or else I would have had plenty of opportunity to get a good closeup of the fellow.
I came back from Christmas in rainy Vancouver and was greeted by this wonderful blanket of snow. It was almost up to my knees when I trudged through it to inspect the goings-on on the berm. Not much is happening. There were very few tracks in the snow except my own.
Around New Years is the latest sunrise of the year, coming up in Ottawa at 7:43AM. From this point on the days are getting longer by more than a minute a day.
Can hardly wait for spring.
Today is the earliest sunset of the year. Hopefully yesterday's snowfall stays around to brighten up the rest of the winter. I only learned last year that the length of the solar day varies over the course of a year due to the earth's axial tilt to the celestial equator. The solar apparent noon varies by as much as 16 minutes from noon over a semiannual cycle. In Ottawa, in November the solar noon is about a quarter of an hour before noon while in February it is about a quarter of an hour after noon. At the equator where there is always about 12 hours of sunlight, the earliest sunset occurs in early November, but because our hours of sunlight, this far north, are still shortening in November sunset continues to get earlier and earlier even as solar noon moves back towards the clock noon.
In the foreground of the above picture you can see several clumps of poplars that have sprung up on the north slope of the berm. These suckers have grown about 20 feet over the past four summers since the mower was banished from the slope. They are already starting to shade the trees planted on the slope in 2009. The planted trees may have to put up with some shade for a couple of decades, but that is the way of natural succession. The sugar maples will still be relatively spindly in 20 years time. The ones planted in 1995 still look like they could be toppled by a couple of blows with a good sharp ax. Poplars are very fast growing but short lived trees. you can see in the background of the above picture one of the parent poplars, planted in 1995, had already grown into a large substantial tree before it was blown down by a wind storm this summer.
The first snowfall of the season fell yesterday. Late November, before the snow flies, is a pretty dreary season and the insect photography opportunities are quite limited. The one bug I have been seeing lately are mosquito like insects hovering around small trees and bushes. As late as last Thursday I saw one hovering around this basswood. More often there are a whole bunch of them bobbing up and down in a little cloud. From what I've read on the internet what I was likely seeing were male midges trying to find a mate.
Midges are a new insect for me. I had always thought that midge was just a generic term for small annoying flying insects, now, thanks to the internet, I have learned they are a family of insects (Chironomidae) that resemble mosquitoes but don't bite. They are very common; large swarms of males are often seen hovering over or just to one side of a bush or tree limb. They spend most of their life as aquatic larvae; the adults don't eat but only live long enough to mate and lay eggs. Finding midges in November isn't surprising as many midges species are cold tolerant; some will even appear in winter to mate. That is an amazing strategy to avoid predators; just appear once the predators have all either died off or have gone into hibernation. It also probably makes it easier to find a mate in the brief time they have before they die.
