I heard of this phenomenom. I think it's called donald ducking (but we can only know for sure if we could see his whole outfit).
i'm not big on beaks. a lot of good furry artists i watch are though. yes it appears to the the face of a duck. or rather an appliance (in the parlance of makeup and costuming people) with the appearance of one. some special thing about ducks? donald's family, darkwing, university of oregon athletics. i also know of at least one platipus fur, and possibly a couple of others. (donald ducking sound like donald trumping, or what your voice sounds like on helium)
