Today I was on I-89 coming from Burlington toward Exit 11. Just after going down French Hill, I saw a good-sized bird flying into the woods. At highway speed, all I registered was big head, wide wings, short tail and all brown. I don't think it was a hawk of any kind. It seems odd to see a Great Horned Owl flying in the daytime (this was about 3:10), but that's the closest thing I can think of. - So if you're in the Williston area, be on the lookout.
