This past Sunday at Ankeny NWR, after successfully chasing the Tufted Duck at Pintail Marsh despite icy winds and rain, Caleb and I headed over to Eagle Marsh for a quick check.
There were five swans in the water, one of which had no yellow on its bill. However, we concluded based on the shape of its facial features that it was still a Tundra Swan, and not a Trumpeter. Yesterday an eBird alert informed me of an as-yet-unconfirmed report of a Trumpeter Swan from the refuge, which I'm guessing was the same bird.
I'm still inclined to think ours was a Tundra Swan, but would be happy to know what more experienced birders think (and if we're correct, to warn others of this possibly misidentified bird showing up in eBird alerts). A photo of it appears in my eBird checklist here:
