Do swans look in windows?

We're reading EB White's Trumpet of the Swan for school right now. I haven't read this story since I was young, but I remember absolutely loving it. I've been wanting to read it to the boys for awhile. I had totally forgotten that the main character, Sam Beaver was from Montana and much of the story takes place here. Small world, I guess. The other day we were reading from chapter 4 where the cob begins one of his long, drawn-out babbling speeches. In this one he's talking about fatherhood ...

"Here I glide, swanlike," he said, "while earth is bathed in wonder and beauty. Now, slowly, the light of day comes into our sky. A mist hangs low over the pond. The mist rises slowly, like steam from a kettle, while I glide, swanlike, while eggs hatch, while young swans come into existence. I glide and glide, swanlike. Birds sing their early song. Frogs that have croaked in the night stop croaking and are silent. Still I glide, ceaselessly, like a swan."

I stop to reflect on what I just read. There's something odd about that paragraph. I ask the boys, "How would a swan know what a kettle is?" They both look at me and Nathan replies, "Maybe he looks in windows when he's flying." Oh dear. That struck me funny and I cracked up laughing. Hmmm, maybe they do. Come to think of it, I've had turkeys looking in my windows. I've had bears press their nose up on my glass doors. I know the squirrels have seen me and a few times I've been chuffed at through the window by deer outside. I can't say I've seen any swans watching me fire up the tea kettle, but hey, anything is possible, especially in Montana!
