So, I took these photos back in March 2012. This entire time, I've assumed they were Cedar Waxwings. But just now, as I went in search of some sort of fun fact to share about the bird so there'd be some text to go along with these, I discovered they're not Cedar Waxwings, but Bohemian Waxwings—the cinnamon color you can clearly see under the tail is one of the most distinctive differences between the two.
Most likely, given when I photographed them, these birds were on their way back up to their summer breeding grounds in the far north of Canada.
As for that fun fact? According to the Cornell Lab of Ornithology, "The Bohemian Waxwing does not hold breeding territories, probably
because the fruits it eats are abundant, but available only for short
periods. One consequence of this non-territorial lifestyle is that it
has no true song. It does not need one to defend a territory."
