A Bird Story (relax, it’s the last one. . . I think)


The official bird of Alberta is the Great Horned Owl. This is a photo of a mother who had made her nest in the hollow of a large dead cottonwood. Year after year, she’d return to her nest to raise her chicks, usually one. I’m told that one year though, she hatched three and kept all alive until they could fly from the nest. The following year however, there was only one owlet, a fluff ball with eyes. Fascinated, I kept an eye on the little one as it kept traveling along the top branch, back and forth, apparently careful not to venture too far while mom kept watch over her offspring.

One day I did not see the owlet and thought that it had fled the nest until no less than 5 adult owls gathered on nearby trees kept hooting in alarm. I carefully approached the dead tree and peered over the bush. There it was! It had fallen and could not be helped as the surrounding rose bushes were too dense for an adult owl to land and too thorny for a human to attempt rescuing it. The owlet looked helpless and I decided that I would call the Wild Bird Rescue organization if, in an hour or so, the owlet was still on the ground.

But this little chick was a survivor. It remained motionless for some very tense minutes while the adults kept hooting. The trunk of the dead tree was impossible to climb and obviously the owlet could not fly as yet. However, next to the dead tree was a more accessible and slimmer one. The smart owlet picked that one to painstakingly make its way up, mom standing guard over its progress. Using its talons on the smoother bark, it moved up toward the next branch, resting for a while as it reached it, until hours later, it had successfully made it to the top branch and to mom. And there it remained, the nest now unreachable yet just a couple of feet away. This photo of mom on the tree next to the nest was taken under very overcast skies.

A few weeks later, both were gone. The following year, the dead tree fell to the ground.

I haven’t heard any owl hooting this year.

More about Birds

With spring warmth and sunshine, suddenly the air is filled with bird calls and songs. Yesterday, it seemed as if a piece of the sky had just landed in front of my RV; a gorgeous Mountain Bluebird. You can see it and hear its call, not exactly melodious I must add, at: http://www.allaboutbirds.org/guide/Mountain_Bluebird/sounds

I had noticed a pair last year so I suppose they return to old nests. Red-Tail Hawks glide ever so graceful on warm air drafts, not a single feather fluttering. In the nearby field Northern Harriers watch over their nest and swoop down on any interloper. Hmm, that would be Queenie. She remains unflappable under these threats, too intent on diving head first into gopher holes.

I spent a few days at a wilderness park determined to identify birds and their sounds. It’s neither easy nor obvious. One was particularly intriguing; a bubbling sound like that of someone softly blowing into a liquid with a straw. Thanks to Google, I found a site that identified various bird calls and songs, and learned that the Brown-headed Cowbird was the culprit. Neither pretty nor very nice, this bird leaves its eggs in other birds’ nest to have them foster parent its young. But it does make a lovely sound.

Another sound was that of the Gray Catbird. Very elusive, it favours dense foliage and is but a blur when it flies into even denser foliage. A couple of years ago, I kept searching for what I thought was an abandoned kitten when I heard a mew in the bush. I had already rescued a couple of cats dropped by their owners so my reaction was natural. Finally, I realized there was no cat when immediately after the mew, I saw a gray bird swiftly emerging from the foliage and flying away. You can see it and hear it at: http://allaboutbirds.org/guide/Gray_Catbird/sounds .

At the site, you’ll have to scroll down a bit to hear the mew sound posted just below the song. I’m afraid that this will conclude my attempts at identifying birds by their call. It proved to be too confusing, except for catbirds, mourning doves, owls, and brown-headed cowbirds.
