Brown Thrasher

Posted by Bob Lefebvre

Brown Thrashers are rather late migrants, usually arriving in the Calgary area in mid-May or even late May, as do their Gray Catbird cousins. The bird shown here was one that actually overwintered here this year. It was first noticed before Christmas 2016 in Airdrie by Heinrich Lohmann.

The bird was coming to a feeder in Heinrich’s yard and continued to do so into March of this year. The photo below was taken on March 10th, and the bird was last seen on March 11th. It may have moved on to its summer territory then, getting a big jump on its migratory rivals (although if so, it will have a bit of wait for any females to arrive back).

It’s not unheard-of for Brown Thrashers to overwinter in Alberta. One was seen in Calgary in December 2015 and (I believe) one in Canmore later that winter. One was seen north of Edmonton in February 2015. Of course, these birds are at high risk when spending the winter so far north. Their normal winter range is in the SE United States. As I said, a bird that successfully overwinters here will get first choice of breeding territories. But it’s also possible that birds that overwinter are only doing so because they were sick or injured during the migration period, and were unable to head south.

In any case it’s always interesting to see a “summer” bird here in mid-winter.

North Glenmore Park and the Glenmore Reservoir

On our visits to the Weaselhead on both May 31 and June 14, we visited parts of North Glenmore Park in search of shorebirds, Brown Thrashers, and whatever else might turn up.

We found a couple of great birds on both days, with a Nelson’s Sparrow and a Brown Thrasher as their usual spots on May 31, and on June 14 we found a Caspian Tern and a beautifully lit Cedar Waxwing during a brief moment of pale sunshine.

This Brown Thrasher has been a regular visitor to the park during the May Species Count, usually found just below Parking Lot “C”, but we also heard two others singing in the Weaselhead that morning, which is a good sign that they’re actually increasing in numbers around here. Their random, rambling, repeating song is distinctive, and usually how we find them first, long before we ever see them. This guy decided to pop up into the aspens and sing for us as we watched.

On the north end of the park are a series of small ponds for stormwater runoff. Thankfully, on May 31, it was fairly calm and clear, so we did get a chance to walk out onto one of the small spits of land where I was hearing a Nelson’s Sparrow singing, and again, he decided to pop out into the open for us to get a few looks at him.

On June 14, I was notified of a Caspian Tern on the Glenmore Reservoir, so after our morning walk a few of us headed over to take a look for it. Thankfully we found it right where it had been seen all morning, at first resting, and then a few times lifting its head to display that bright red bill and gape at some of the low flying swallows. Perhaps it was simply tired of being buzzed by their nearby flights!

We went over to look for the Brown Thrasher again, but sadly we only caught a brief glimpse of it. We did find this Cedar Waxwing sitting nice and pretty in the same tree that the Brown Thrasher was singing from two weeks prior.

Have a great week, and good birding!
