As I said, it's probably meant to be a vulture. Specifically, it's probably meant to be a red-headedvulture, that being the generic image of a vulture as far as most Americans are concerned. However, it looks enough not like one - the beak in particular is really jarring if you're at all into ornithology - that it could easily be something else (it looks as much like the aforementioned black stork, for instance, as it does like our red-headed vulture, being equally off-model for both). Basically trying to get any meaning out of a bird drawn like that is like being handed a spork as your only clue for what you're getting for dinner.
