If I remember correctly, they excrete liquids/solids from the same orifice, which is why it is usually white…
Found more info on why it looks white:
Strictly speaking, bird poop itself is not white – it is in fact the urine element of a bird’s waste that gives it this distinctive color. Birds do not have a bladder that functions in the same way as a mammal’s does, and are adapted to make themselves as light as possible to enable the maximum flight efficiency at all times.

I decided to quote additional information from the source above, for those curious:
What makes bird poop white?
As birds do not have separate organs for urinating and defecating, all waste is excreted through one single opening called a cloaca. The cloaca serves as an entrance for reproductive purposes, for laying eggs, and as an exit point for excretion of bodily waste. The white sticky paste pooped by birds is uric acid, the equivalent of pee for birds.
What type of bird poops white?
The droppings of all bird species will contain some extent of the white uric acid component, but the rest of the feces may also be colored according to the bird’s diet.

They reproduce by rubbing butts as well.
Quit blowing my mind lol. What’s this butt rubbing shit… I thought males and females have different organs?
They do, but the cloaca is pretty much ubiquitous on birds.
