A cloaca is a common chamber and outlet into which the intestinal, urinary, and genital tracts open. It is present in amphibians, reptiles (therefore dinosaurs), birds, elasmobranch fishes (such as sharks), and monotremes. Plancental mamals and most bony fishes have an anus.
anus is an opening through which waste material get excreted but cloaca is a small chamber that is used to pass faecal matte,urine and sperms to the exterior.
It is called a cloaca, pronounced klo-a-ka
Tortoises defecate through their cloaca, which functions as their anus.
A pig does not have a cloaca because they have both reproductive organs and an anus. Only animals with 1 opening have a cloaca.
Liquid waste is eliminated from a frog through its kidneys, which filter waste and excess substances from the blood to produce urine. Urine then travels through the ureters to the cloaca, where it is expelled from the body as waste.

Owls, like all birds, have a cloaca for all excetory functions.
In frogs, the cloaca is located posterior to the large intestine and anterior to the anus. It serves as a common chamber for the excretory, reproductive, and digestive systems, collecting waste products from the large intestine before they are expelled through the anus.
Monotremes, the echidna and platypus, have a cloaca. Monotreme means one hole, and is a reference to the cloaca.
Yes, like all birds, buzzards excrete waste through their cloaca, which is a single opening used for the expulsion of both waste and reproductive fluids. This means that their feces, which can include undigested food, are expelled from the anus as part of this process. So, while it's not technically called an anus in birds, the cloaca serves that function.
Remember that dinosaurs were the precursors of birds and they were also reptiles. Birds and amphibians, male and female, have a sexual organ called a cloaca which they would press together to exchange sperm. However, reptiles do have an internal penis, that only appears externally during sex, which would be used with the female's cloaca.
