Birds have to eat alot to afford the energy required for flight; hince the droppings. Also, their bodies try to keep them light so they can fly, so they don't ruminate their food as much as mammals.
Another interesting fact about birds is that they never urinate. All of their bodily waste goes out the same place as a solid (or simi-solid). So what you call bird "poo" is also bird "pee"!

It's true that birds have only one exit for bodily waste. It's called the vent or cloaca. The white part of their droppings is like our urine, and the brown is like our feces. Birds poop so much because they have a much higher metabolism than people.

Birds have a fast metabolism. They have to eat a lot, and it goes through very quickly. In one end, out the other.

they are small == small stomach, easy disgestion
and because poo and pee come out of the same hole, so it happens twice as much

They eat a lot.
They eat a lot because they are small warm blooded creatures.
