I’ve watched loons intimately for 25 years, and I just noticed a couple of splendid bits of camouflage for the first time. The light was right. First, the tail. Not only does it hold a chick on that scooped back but in the absence of a young chick riding up there, it looks like one. Confuses an eagle like all get out, I suspect. Eagles aren’t that bright. Thing is, there are two loons, rarely together, and usually one chick, often floating alone in the middle of the lake, on the principle that eagles are punctual (they are) and can be relied on (well, not really; they’re slouches). The chicks are often riding, though. When larger, they’re swimming at a parent’s breast, usually Mom’s, although Dad brings fish, so that’s good. And look at this second bit of camouflage: a ghost chick swimming along at the breast line. It’s all in the feathers.
Or is the chick in behind and slightly older, with its head peeking up, going in the opposite direction as Mom? An eagle is slouching at speed. It can count, but, sheesh, where to go? This moment’s hesitation is why there are still loons, because by the time the eagle has figured out, it has passed by. Beautiful!
