Yes, it is called an anus.
Birds do not urinate. They expel a mix of urine and feces (poop).
Urine is liquid Feces are solid
Birds do not urinate as people do. Their urine is excreted with their feces. Their feces is actually brownish-black in color and the white you see mixed in with it is the "urine", which is actually very concentrated urea, not urine itself. Also, usually the bird feces can be white with a black spot or dot, not the other way around.
Urine and Feces are just the scientific name for pee and poo.
Through an opening called the cloaca, like all birds. This one opening is used for urine, feces, and all sexual functions.
Cats use urine to mark territory. Their feces doesn't do much.
Birds, unlike mammals, don't produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste.
Because birds eliminate water and solid waste from the same hole in their body, they don't have a hole for urine and a separate hole for solid waste.
Urine is basically sterile unless you have an infection. Feces are FULL of bacteria. But you should not get in the habit of drinking urine! It is still body waste.
Feces and urine
They don't. Like all birds, they excrete urea (not urine) along with their feces through the cloaca. The urea is very concentrated and is the white portion of the droppings, whereas the dark colour is the feces.
Mostly by urine and feces.
