One of the main behaviors that can be observed in birds is “preening”. Through this special activity, birds remove parasites, dirt, dust etc. from their feathers while repositioning that particular feather next to adjacent feathers. This process helps to keep the bird healthy. A gland named ‘Uropygial’ or simply the preen gland is situated at the base of their tail which produces an oily substance to keep their feathers glossy and shiny.
