Except in certain circumstances, birds do not 'poo' on you consciously. A bird, when it feels the need, will expel it's waste, even when flying. If you just happen to be underneath when that happens--well, you know the rest.
In some circumstances, certain birds employ a method of driving off predators, whereby they will actively 'dive bomb' the offending target (that could be you), releasing the foul smelling mixture.
Birds land on you if you are wearing bright colors and are fairly still, just so they can have a resting place.

All birds can land. Some, such as Swifts, normally stay in flight for most of their lives (except, for the females, to raise chicks). They may find it very hard to take off again.
