Nest hygiene in wattlebirds

Many nestling birds, especially the passerines, produce membrane-covered faecal sacs on a regular basis as they grow.

Sometimes these sacs (usually white in colour with a black tip) are deposited over the edge of the nest, or commonly they are removed by the parents to keep the nest clean and hygienic. As this series of images shows the sacs are also sometimes consumed by the parents.
