Three-dozen or so pigeons were perching on a utility line in the alley in back of my neighbor’s house this morning. Suddenly, all the birds took off.

What spooked them? I’m sure it wasn’t any movement I made from inside the house. Then a crow came along, and the black bird found himself the object of harassment when the flock of pigeons swooped at it. A moment later, the pigeons were gone, and the crow found a perch on the streetlight in front of the neighbor’s house.

A few minutes later, the crow moved on and the pigeons were back in residence doing their high wire act.

Last summer, I was intrigued to see a red squirrel scrambling along the top of the wooden fence in our backyard. That was a surprise, as it was the first time I’d ever seen a red squirrel in Butte. The squirrel didn’t hang around long, as half a dozen magpies, that also didn’t think the squirrel belonged, were chasing it.

Moments of wildlife drama, and it’s just one of many such moments that take place every day right in our backyards.

These vignettes are my way of noting that this coming Presidents Day holiday weekend, it will again be time for the annual Great Backyard Bird Count.

The Great Backyard Bird Count is a joint project of the Cornell Lab of Ornithology and the Audubon Society, along with their Canadian partner, Bird Studies Canada. This weekend will mark the 15th annual celebration of birds in winter. Last year, participants submitted over 92,000 reports of bird observations, the third consecutive year of observations exceeding 90,000.

The goal of the Great Backyard Bird Count is to get a continent-wide snapshot of bird populations and their distribution, and to get a handle on trends that may be happening. For example, last year, the most numerous bird counted was the European starling, a bird not native to North America. In 1890 and 1891, 100 starlings were introduced to New York’s Central park. A little over a century later, the descendants of those birds now number over 200 million and are distributed across the entire continent.

Snowy owls are birds that have been in the news in recent weeks. These are arctic birds but this winter there have been sightings across many northern states, including Montana, and as far south as Boise, Idaho. With our generally snow-free fields across southwestern Montana, this might be a good weekend to take a drive in the country to see if any of those snowy owls are in our area. These large, white owls should be easy to spot.

Participating in the Great Backyard Bird Count is easy. Just make a point of spending as little as 15 minutes on one or more days this coming weekend: Friday, February 17, through Monday, February 20. You can do this from inside the house, or go for a walk in your neighborhood, or go for a drive around town or the countryside. Make a note as to what birds you see and how many, and then when you get back home, log onto the internet to www.birdsource.org/gbbc, and follow the instructions on how to submit your list.

This could also be a good group project for a class, family, or scout troop. It’s a great way to introduce kids to nature and the wildlife that lives around us.

As for this weekend, let’s note that the holiday officially commemorates the birthday of our first president, George Washington, who was born February 22, 1732. Actually, at the time Washington was born the British Empire still followed the Julian calendar, which by that time was 11 days out of sync with the Earth’s orbit around the sun. So, Washington was born on February 11 on the old calendar.

The British Empire adopted the more accurate Gregorian calendar in 1752, skipping from Wednesday, September 2 to Thursday, September 14, and in 1753, Washington celebrated his 21st birthday on February 22.
