New goose species?

I came across the strangest thing today on one of my usual jaunts through the woods. I was keeping my eyes peeled for the piliated woodpecker, as always, when I noticed what must be a hybrid goose species. It had blue markings on the bill and I could have sworn I heard it speaking in plain English. I assume it was male, and he seemed to be giving himself some sort of inspirational pep talk. He took off before I had a chance to decipher his honking. I’ve been searching through my textbooks all night and I can’t find anything even remotely related to its characteristics. Could I have discovered a new species? I’m going to go out first thing tomorrow to search for it again.
