I'll take Canada Geese over vultures or buzzards!

I used to spend most weekends sailing at Nockamixon, and the turkey buzzards would just love to perch on top of sailing masts, which created two problems:
1. Those birds are effing huge, like a Beagle with wings, and they'd actually break wind vanes and other mast heads, due to their weight and hard landings.
2. They'd crap all over your boat, while perched on the mast. And this isn't the nice lilly-white crap of a Blue Jay, it'd be big bloody dog turds, all over your boat deck or cover every Saturday morning!
The geese do tend to leave huge minefield swaths of their turds on the lake shores, probably worse at Galena than Nockamixon, but at least that's not coming at you from above! And they're not covered with or filled with blood, like the buzzards.
Speaking of vultures and sailboats, I remember seeing a deer get hit on Mountain View Drive (Rt. 563) on my way to a sailing race one morning, freshly killed around 9am. By the time I passed it on my way home around 2pm, it was a stripped-clean skeleton on the shoulder of the road! Those birds work fast.
