Swans Mystery

Back to the mystery swans we encountered at The Wilds. As some of you web-savvy readers have already determined, these were trumpeter swans. I should pay more attention when I name my images for uploading!

Before 1900, trumpeter swans were extirpated from most of their North American breeding ranges by hunting. Only a remnant breeding population remained in Alaska and remote parts of the West.

During the 1990s there was a captive breeding and reintroduction program for trumpeter swans here in Ohio. The Wilds served as a captive rearing facility for birds hatched in captivity. The goal was to acclimate the birds to living in the wild so they could later be released along the Lake Erie marshes. More than 150 swans were released and today there is a small breeding population. At The Wilds a few birds are still around. I assume the flight feathers on their clipped wings grew back and they are now fully flighted, but don;t really know where to go.

The weird thing about these two birds is that one had black legs and one had yellow legs—at least the upper parts of the legs we could see above the water. You can see this in the photo below: the right hand bird has the yellow upper legs.

We checked the birds carefully in the spotting scope. Black bills eliminated mute swan. No pale yellow lore leaned us toward trumpeter. The notably long, straight black bill also pointed to trumpeter. The yellow-legged bird also was banded.

Yep. Captive but free-flying trumpeters.

Knowing that trumpeters had been captive-raised here, it's exciting, but not that exciting, to see them. Now if these had turned out to be tundra swans, we'd have been a bit more stoked. Tundras fly right over southeastern Ohio in the late fall/early winter on their way to the Atlantic Coast. Seeing a couple of tundra swans is always a notable event.

Odd swans are the least weird thing one can see while birding at The Wilds. More on that soon.

At The Wilds: Mystery Birds

The Saturday after Thanksgiving we took the kids birding to The Wilds, a 20,000-acre recovering strip mine that's an endangered animal breeding and research facility. In the temperate months you can tour The Wilds in one of their buses. But most bird watchers visiting The Wilds just like to drive the roads to see what birds are around, in the vast grassy fields, and the many ponds and lakes that dot the landscape.

On the south side of The Wilds there's a long, string-straight piece of road that passes a couple of long, narrow lakes. Well, calling these lakes might be a bit of a stretch—they are not naturally occurring. Really, they are deep scars in the earth, cut by massive machinery as it removed seams of coal. Now these giant holes have filled with water.

That matters not to the waterfowl that pass through these parts. The two white birds above were on this lake, loafing and preening. Swans, at first glance. But which swans?

More on this line of inquiry tomorrow.
