Of owls and other birds




Not only wildflowers, birds, too, are back in full force. This afternoon I watched four robins splashing in the pond in front of the house to which the gold fish returned from their winter quarters in the basement a week ago. Chipping sparrows and white-throated sparrows are adding their voices to those of the robins, from time to time a blue jay interjects its hoarse voice. Right on time – though sadly no longer at our place for the last couple of years – the swallows came back on May 11; it is amazing how faithfully they arrive at this date year after year. Only the hummingbirds are still missing: they usually come back on May 22 or 23, and I will keep my eyes open for the first tiny shape on the top branch of the dead poplar tree across from the back porch, a favourite perch. 

Unfortunately a whining, almost cat-like voice has been alerting me several times a day to the presence of a bird unwanted in the yard because of its harmful habits: the yellow-bellied sapsucker, or rather a whole clan of them, it seems. Already the pines beside the back entrance bear witness to their diligent efforts to secure food, neat rows of holes weeping sap, a perfect trap for insects which, along with the sap, provide sustenance to the birds. The pines seem to be able to withstand this abuse, although their trunks are scarred and creviced, but birch and fruit trees for instance become prone to fungal infection in these wounds and often don’t survive. Needless to say I am not thrilled to see the sapsuckers. They seem to have finished the drilling for now, probably just coming back to collect food; I don’t see them that often anymore.



At the beginning of the week, however, I had a most wonderful bird encounter. Back in March already my friend Glenice told me about a pair of Great Grey Owls (Strix Nebulosa) she saw regularly when she went cross-country skiing in a friend’s pasture, about three quarters of an hour from our place. They occupied a nest where a red-tailed hawk had nested several years ago, and for a while Glenice saw the female sitting on the nest. Neither of the owls were concerned with the presence of humans, and by now an owlet, possibly two, have hatched; Glenice wasn’t sure. She had invited me to come for a walk and see for myself a couple of weeks ago already, and on Monday it finally worked out for both of us. 

We got there mid-morning, the road and pasture still muddy from the recent rains, but at least dry from above. Janice, the owner of the pasture, decided to come with us, and we neared the nesting area talking quietly, enjoying the beautiful spring landscape, the fresh green of newly leafed-out poplars. ‘Here we are,’Glenice said when we had reached an area of high trees with not too dense underbrush. And really: there was the nest, maybe three or four metres above the ground in the fork of two sturdy poplar branches. The female was sitting quietly, and a chick showed us its light coloured back. The mother stretched her wings for a moment and then flew off to a nearby tree, settling down and calmly watching the nest, sometimes turning her big head with the beautiful markings to gaze at us. To me, great grey owls look old, somehow, and wise. Never before had I seen one of these huge owls - the largest species of owl in the world by length if not by weight – that close, for such an extended period of time. My viewings mostly happened from a car, just a glimpse, and every time I am thankful when that occurs. This, however, was almost magical. 

We alternately watched the mother and the nest with our binoculars. Suddenly I saw a second owlet half hidden behind the trunk of the tree, soon raising itself up to its full height and looking down at us. Its sibling had turned around now, too, and the two funny little dark owl faces with their lighter coloured beaks were in full view. The mother, still not at all concerned about us, made little cooing noises from time to time, not unlike a mother cat or a cow talking to her calf, but she made no attempt to return to her brood. A little while later a third chick appeared between the other two, maybe a little smaller, but undoubtedly alive and well. We were amazed how the nest, not overly big and rather flimsy looking, could hold all these birds. The mother had been with the chicks at first, after all, and they all found room somehow. What a wonderful experience to watch this family!

This was not to be all yet, though. I had noticed for a little while already that the attention of the female was no longer fixed on the nest or us; she was looking in a different direction. The sounds she made had changed, too, the calls a little louder, closer together, but still no hoot, more a brief call. A second large owl swooped in: the male had arrived. He was doing what owl males do all through the nesting season: bringing a mouse for his mate. He sat on a tree nearby, the female flew up to him, took the mouse, and the male left right away again. The mother shifted the mouse until it was positioned just right before it disappeared in her beak. A moment later I watched her swallow, the mouse gone for good. How lucky we were to see all of this in one single visit! After half an hour or so we turned back to the road, watching a couple of brown backs receding through the bush, maybe fifty metres away: two yearling moose, judging by the size. 

Of course I looked up more information on the Great Greys and found out that they are less shy and secretive than other kinds of owls, that encounters like ours are not uncommon.  The owlets fall or jump from the nest when they are three to four weeks old, but since they cannot fly yet for another two weeks they have to climb back into the nest. This is when they are most vulnerable, of course, and the mother is very vigilant during this time, ready to defend her young when needed. Once the young owls can fly the mother usually goes off on her own, leaving the father to feed the offspring, which he does until they are able to hunt on their own by autumn.

When it's spring time in Alberta ...





It’s been a very long time since I last posted anything, and right now we should be about as far removed from harvest as we could possibly be: it is spring, even in Alberta, after all! 


While this is true for our farm it sadly isn’t for many other farmers here: the wet conditions in the fall led to a lot of crop being left out unharvested last fall. Some went out late in the fall, even in December yet, when there was not much snow and the weather dry, and combined as much as they could, others took advantage of a few good days in the last week or ten days, but still there are many fields with canola swaths, some with wheat and even barley, some uncut and now flat on the ground after the spring snows, of course. Even if it could be salvaged much of it will be mouldy or contaminated by deer and mouse droppings.

We haven’t been faced with those particular challenges – we’ve had our share of those twice previously, years ago – and had been hopeful that we could start our field work reasonably timely. These hopes were dashed a few days before Easter when we received 50mm of moisture, about half of it in rain, the other half in snow. The ground was still saturated from the wet fall, and this made matters much worse than they would have been in a drier year, of course. Again the puddles slowly went away, wet areas in the fields started to dry up – until the next snowfall about ten days later. 
The water pools on the lawn are still big enough for Leo to bathe in
We usually say that we cannot even think of field work until the ‘lakes’ in the lawn have dried up, but about a week ago a few warm, windy days made it possible for field work to start, even though low areas still had to be left out. We have about one fifth of our acreage seeded now, but after about 20mm of rain these past few days we have to wait for things to improve again. We haven’t had a spring this wet in a very long time, and the gravel roads are in very bad shape, some of them nearly impassable with a smaller car. 
 
Beautiful day in late April

The upside to this is that everything is wonderfully green. Ducks and geese must be revelling in the abundance of water, and the frogs have been muttering their hearts out from every little pool of water for weeks. I have been enjoying ‘my’ forest where every walk brings new discoveries.A few weeks ago I watched the courtship dance of two red-tailed hawks, and after a few walks where they complained about my presence it is now very quiet: she is likely sitting on the nest, not drawing any attention to herself. Robins, chickadees and white-throated sparrows are singing, and already green walls have grown up where I could look far between the white trunks of the poplars: the underbrush is hiding animal trails from view. By now, however, I know how to find many of them since I am becoming more and more familiar with my trail, recognize oddly shaped trees and family groups of others, know where tree fungi have grown like footholds on a climbing wall and which trees are most favoured by the woodpeckers. 


Things change every day at this time of year. The first wildflowers are in bloom, and when I knelt down to inspect some small plants more closely on yesterday's walk a sudden sweet scent enveloped me: the creeping stems of sweet woodruff with their whorly leaves crushed under my knees. The most stunning find, however, just like every spring, were the clumps of golden marsh marigolds that had pushed up all along the edge of the swamp. For me, this means it is now truly spring.
