When preening, a bird (such as this red lory) draws individual feathers through its beak, realigning and re-interlocking the barbules. Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.

The uropygial gland, informally known as the preen gland or the oil gland, is a bilobed sebaceous gland possessed by the majority of birds used to distribute the gland's oil through the plumage by means of preening.
Among animals, birds spend considerable time preening their feathers. This is done to remove ectoparasites, keep the feathers in good aerodynamic condition, and waterproof them. To do that, they use the preen oil secreted by the uropygial gland, the dust of down feathers, or other means such as dust-bathing or anting.

Bird flu can be diagnosed by testing samples taken from a sick person’s nose, throat, or eye, but testing is primarily recommended for people who have symptoms and have been recently exposed to ...
The bird flu outbreak continues to spread in the U.S., affecting more than 100 flocks in 18 states over the past 30 days. However, the risk of a person contracting the illness is low.
The practice may also act to supplement a bird's own preen oil. A third purpose may be to render the insects more palatable, by causing removal of distasteful compounds. More than 200 species of bird are known to ant. [21] "Passive anting" refers to when birds simply position themselves so as to allow insects to crawl through their plumage. [6]
