Please note: This article
This posterior opening is not the whole cloaca but only its visible part. The cloaca is a part of the digestive tract and it is a small chamber with a mucous membrane. In some cases this tissue can slip through the posterior opening. Vets talk about a cloacal prolapse. In most cases, female birds are affected by this health complication while they're laying their eggs. But also male birds can be affected by it. A cloacal prolapse is a life-threatening condition!
In budgies, the part of the body close to the posterior opening is covered by white down which is clean as long as the bird is healthy. If a bird suffers from diarrhoea or polyuria, faeces or urine stick to these feathers in many cases.
