Do barn owls use the bathroom?

Yes. Barn owls use the bathroom just like other animals do. Owls produce three types of waste: liquid urine, semi-solid urates, and solid feces. Owls excrete urine and urates through the cloaca, an orifice which also functions as the reproductive vent. Feces are eliminated through the cloaca as well. Barn owls often leave behind white-colored splotches of urates when perching or roosting as well as brown- or black-colored droppings of feces
