No feeding the birds - including feeding chicken fingers to the ducks - which my kid thinks is hilarious!
Seriously though, as odd as feeding ducks chicken fingers is, I think most of the damage is done with fries. 
Not even just bending over...
Yeah them and the white crane birds sometimes take your food without you giving it to them.
Proper attire is a huge issue. My daughter constantly points out females dressed like they are ready for the club not Disney.
I think the hard part is that "commercial" gear is a hard line to define these days. More and more people have various levels of high-end cameras and glass these days which only a decade ago was limited to a much smaller segment. The Forum (formally the Ice Palace) here in Tampa where the Lightning play has rules about length of lens for example in an attempt to limit pro gear. But it doesn't truly provide an accurate limit on pro gear.
My guess is that they left it vague so they can determine on a case-by-case basis in the park when they feel something is too large. But of course, that makes it highly subjective and one CM's definition of "too large" might not be another's idea leading to confusion, frustration and uncertainty on the part of the guest.
VERY good comments here. Maybe some of us should whip up a list of rules and submit them to Disney. We're the ones who have to see those t-shirts and listen to those idiot chants and put up with the morons taking flash pictures on Pirates of the Caribbean!
No wonder those ducks are fat and happy
My son gets upset with the ducks at FlameTree BBQ demanding handouts. Don't mess with a boy and his food.
Dont you mean for a "prostitution hotel" ?
Hey now, if they can get away with showing stupid Captain EO still, then why can't I use my VSH camcorder?
No joke, especially the freakishly aggressive ones that sit on top of Golden Oak Outpost and swoop down at yours as you start to walk away! We had one knock some right out of my husband's hand...
