Crocodile bulks of swallowed prey flesh and bone. Many large crocodilians swallow stones (called gastroliths or stomach stones), which may act as ballast to balance their bodies or assist in crushing food, similar to grit ingested by birds.

Quail-plover like the wind going through a pipe during moonlit nights. The Sahel from southern Mauretania and northern Senegal eastwards to northern Cameroon and southern Chad into South Sudan and southern Sudan with separate population in northern Benin and coastal Ghana, with another in Uganda, Kenya and Ethiopia. The quail-plover has an extremely large range, its population trend is not known, the population is not understood to be undergoing a sufficiently rapid decline to approach the thresholds under the population trend criterion while the population size has not been quantified so the species is evaluated as Least Concern.
