for example pidgeon poop

[texol]

Humans can be toilet trained, so can dogs, cats and even rabbits but are there any other animal that can be? Also does for example does a pidgeon know when it needs to poop or do they just do it anywhere at anytime(as lucky as it supposed to be) without knowing that they are doing it? and please this is a serious question.

I think they normally jettison their load just before take-off,especially if alarmed..(pigeons that is)

No, they tend to aim for people with dark clothing and no hats!

They are trained by their parents from a young age to drop their toilet whenever they are immediately above either a walking human being, or a washing line of freshly washed sheets.

Seriously, I suspect they just do it whenever their little bowels are full. Not being basicially grounded animals like cats or dogs, they have no need to seek out appropriate toilet grounds, so can just go anywhere at any time..

Judging by the amount of guano building up on the catch on my garden gate, i would say their pretty much poopers of habit !
