Counting Birds

Tuesday I participated in the Belleville CBC (Christmas bird count), organized by the Quinte Field Naturalists. It was my second time out, and what a difference from last year.

Last year the temperature when I left the house was -18C, the high that day was about -10C. There was some wind blowing in our faces for the trail portion of the event (a hike of about 3 hours). And for the first hour or so, almost no birds at all were so foolish as to be up and about in those temperatures. But we did see birds that day, 18 species plus a bonus of a flock 300-400 snow buntings in a field just outside our count area.

This year the temperature was just below 0C when we started, and rose to just a little above. (This has been the temperature around here for the last several days.) It was cloudy, but there was no rain or snow, and the sun broke through in the afternoon.

We started out slow: a few birds at feeders on the drive to the trail we would hike, but then things got better with the spotting of the first northern shrike--sitting high in a tree, at some distance away. Then a second, a little further along, flew into an apple tree, and out again with a piece of apple. After that it stayed with us for several minutes flying to one spot and then another on the sides of the trail, giving us some excellent views. One of the other counters and I got pictures. I think his were probably better. One of mine confirms the sighting (the other was entirely out of focus), but is way overexposed for reasons unknown to me.



Tracks in the snow on the trail included squirrel, rabbit, muskrat, deer, coyote, and one of the larger members of the weasel family, small otter or mink maybe.

After the trail we got into one of the cars headed back to the others for lunch, then headed out for the driving portion of the count in one car. Last year there were just two of us--so only one watcher during the drive. This year with four I think we saw more birds more safely.

We did finally see a red-tailed hawk, just as we were beginning to despair of being able to count at least one of these normally ubiquitous raptors. But we never saw any wild turkeys, although I did have a flock of these guys fly across a road behind me on the drive down to meet the group (and that's one weird sight to see in your rearview mirror!). Towards the end of the afternoon I think it was me who cried "stop" for some robins hanging out by some apple and sumac trees. We saw that they were indeed robins--first time for us that day--first time for me since much earlier in the season--a good bird to count. We got out of the car for a better look when another in the group cried "bluebird!" And indeed there were, five eastern bluebirds, possibly a family group, as there seemed to be only one mature male. They weren't with the robins (who left soon after we arrived), but were presumably attracted to the spot by the same food source. As we watched they flew down, one or two at a time, to eat the fuzzy, red fruit of the sumac. Mourning doves were the most numerous of the birds we saw, and in the bit of coverage remaining we counted many more--then the last bird added to the list, a flock of 50 snow buntings!

Not a good shot either--but you might be able to make out that this is indeed an eastern bluebird

I've learned since Tuesday that the Belleville count area is a circle with a radius of 12 kilometres and its centre at the Belleville city hall (front steps). Nuthatch of Bootstrap Analysis wrote this week of an interesting tool available from Google that can be used to create precise mappings of CBC areas, describing how to go about this--all you need to know is the centre point (well, you also need broadband and a newer operating system than Win98). I think you also probably need a club (like the Quinte Naturalists, not like a baseball bat). I'd like there to be a count that includes Thomasburg some year, but it takes organization to get people out to cover the area on the appointed day. Something to think about though--isn't it Peter? No hermit thrush so far in the count (see species list below), but a sighting might come in as a count period sighting--any species identified in the circle between Dec 24 and Dec 30. These birds aren't counted, but their presence is noted. I won't hear for a little while what the final species list is.

I'd recommend this to any birder--even if you have to travel a little to find a count. It's an excellent time of year to take a whole day off and do some birding.

Pity the Poor Mourning Dove

Last week, in the middle of a sunny afternoon, a sudden wave of birds flew across the yard from the pines at the back, and away--chickadees and mourning doves, for the most part. A feather or two floated in the air. I thought there must be something dramatic going on--but couldn't see anything from the house, and I wasn't dressed to climb the hill in all that soft snow, as it was then.

When I walked up the next morning the evidence was there. Something, and I suspect the red-tailed hawk that's been hanging around for a couple of weeks now, ate (I am guessing) a mourning dove, sitting on the path right near the shed. If I'd walked up when I noticed the exodus I might have seen it. On the other hand, I'd probably have chased the hawk off its meal, and life is tough enough for predators, especially this poor bird that is almost constantly harassed by the neighbourhood crows.

The meal was taken in a snowshoe track--you can just make out a wing print in the edge of it.

The size of the wing print is part of what makes me think that the diner was a red-tailed hawk.

These are just a few of the feathers that littered the ground--but feathers was all that was left.


The quantity and quality of the feathers is what makes me think this was probably a mourning dove. The mourning doves spend a lot of time sitting in the pines at the property line. They spook very easily, but this time the hawk was quicker.

Pity the poor mourning dove. Hooray for the hawk!

Winter Birds

Wonder of wonders--today a flock of 15 to 20 pine grosbeak. This is the first time I've seen this bird in Thomasburg, though early last spring a flock visited friends of mine about 10km northeast of here as the grosbeak flies.

It was very grey today, and the birds insisted on either sitting quite high in a deciduous tree or feeding in a coniferous tree, so it took a while for me to get a good enough look to identify them. But what a treat, and what a pretty bird!

An hour or so after I saw the grosbeaks, the first common redpoll of the season came to the feeder--all alone, which is not the redpoll way, but it looked as if it were travelling with a flock of goldfinches, so perhaps not lonely.

For more winter bird stories, and summer stories from the lands down under take a look at I and the bird #13 at Woodsong. The presentation is beautiful, in keeping with Cindy's beautiful blog, and includes a wide variety of great posts, for example a story about Penguins in Antarctica in dire straits from 75 Degrees South and a stunning varied thrush from Dharma Bums. And much, much more.

The federal election campaign, straddling the holiday season, has been a terrible distraction for me from what I'd much rather be doing: watching stuff, and reading the other nature bloggers. It's good to have so much good nature writing, of the bird variety, in one place, so that I can go back again and again and always find something more to read.

For more information about the carnival go to the home of I and the Bird. The next edition will be hosted by Gwyn at Bird Brained Stories on January 5, 2006. Send submissions to Gwyn or to Mike at I and the Bird central by January 3, 2006.

Snow Spider

A beautiful weekend, not too cold, not too warm--and lots of snow. My weekend visitor and I got out on the snowshoes--and he spotted this critter on an untouched expanse of snow way out in the open, far from tree or shrub.


The spider was moving when we first came up to it--but soon stopped. How did it get there? It appeared before we were close enough to have dropped it out of our clothes (yes, there might always be a spider hitchhiking on someone coming out of this house). I think it was too cold for it to have walked from a hibernation spot. Perhaps dropped there by a bird who had dug it out of a crevice somewhere?

But which weasel?

Sign like I've never seen before out in the snow of the first field this morning--nice deep fresh snow--25 to 30 cm. It may explain the odd tracks coming out from under the shed--but this kind of snow, damp but not too damp, and deep, doesn't show a lot of detail. A casual glance and an expectation of rabbit suggested rabbit, but later observations and a little thought, not rabbit.

Here is a line of the trail created--you can see the body print--almost like what an otter leaves, but narrower, and with less pronounced and smaller footprints.

Out in the field I found a trail showing a body print that ended with an animal diving under the snow and coming up again a metre or two beyond leaving a perfect round tunnel about 4 inches in diameter. (Sorry, I don't really think in metric when it comes to small linear measures, I just pretend sometimes. I really do think in celsius when I think about temperature, and kilometres when I think of driving distances.)

The glove is just under 4" wide.

This diving under the snow is a weasel trait. The holes this creature left looked too big for weasel to me. So I consulted the books. None of my tracking books talk much about the kind of sign this mode of travel leaves--they talk more about the experience of seeing a weasel bounding across the snow and disappearing, only to reappear several feet on.

There was a suggestion though that a long-tailed weasel (or ermine) might leave this big a hole. On the other hand, the size fits a marten or a mink better. Fishers don't generally snow dive this way--and I think would leave bigger sign than this. Argument for weasel: habitat. One would be more likely to find a weasel in a fence line or under a shed than either of the other two. Mink generally hang around and in water. Martens are more inclined to forest. But any of them might be moving around in winter. I've found otter sign (tracks and slides) in the cedar bush in winters past, and that's pretty far from suitable otter habitat.

The tracks, trails, tunnels, lead from under the shed out into the field and into an old groundhog burrow in an old mound left by a topsoil harvest of several years ago. I fear our latest yard rabbit may have been eaten by this visitor last night (not that I found remains, just that the yard rabbit has in the past hid out under the shed, and there was no rabbit visitor to the bird feeders last night). But even so, there may be enough rabbits and nice places to hole up to keep this creature around for a while--so maybe, just maybe, I'll get to see it. If it's white, it's a weasel. If it's very dark, it's a mink. If it's a little lighter, and cuter, it's a marten. So if I do get to see it, I think I'll be able to identify it. But even if I never do--what a pleasure it is to see strange new spoor out there.

Sightings

The cold snap is over -- low last night was a mere -15C (compared to -27C the night before), high today -5C -- so snow is on its way: 10-30 centimetres promised starting tonight and continuing through most of tomorrow. Not so good that last because I have to go to Belleville tomorrow evening to pick up a friend at the train station. But it is good in that it's time to wipe the slate clean out in the fields. The rabbits have worn trails, trenches really, in the snow so thoroughly that I can't see who all might be using them; and there are so many fox tracks criss-crossing everywhere, and pee stains, I can't sort out the signs anymore.

"This place is mine."

I had a bunch of errands to do this week up in Tweed and environs, so, anticipating the snow, I got them done today (and met other citizens of the hamlet and other outliers up there doing the same). On the way out of Tweed, but still in the village, a muskrat crossed the road in front of me, heading in the direction of the lake on whose shores the village sits, but coming from where? A muskrat is a sleek and elegant creature seen from above swimming underwater, but it is a funny looking, humpy creature on land. And from the side its flattened tail looks like a bit of string dragging behind it.

I got home and a few mintues later I finally got to see what's been bugging the crows all day--a beautiful, big red-tailed hawk flew past the house, crow giving chase.

But these aren't the sightings I am here to write about today. Rather I wanted to report the sighting of an eastern cottontail in a backyard in downtown Toronto, reported to me and documented photographically by the friend I'm expecting tomorrow. He suggests that maybe the rabbit had decided to give up life in the ravines, among the foxes and coyotes, for life on the streets. Whatever the case, the streets of Toronto just keep getting wilder and wilder.
