Most species of birds have external nares located somewhere on their beak. The nares are two holes—circular, oval or slit-like in shape—which lead to the nasal cavities within the bird's skull, and thus to the rest of the respiratory system. [10] (p375) In most bird species, the nares are located in the basal third of the upper mandible.
Nostril. A nostril (or naris / ˈnɛərɪs /, pl.: nares / ˈnɛəriːz /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove ...
The beak, bill, or rostrum is an external anatomical structure of birds which is used for eating and for preening, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young. Although beaks vary significantly in size, shape and color, they share a similar underlying structure.

The jaw muscles, which allow the bird to close its beak, attach to the proximal end of the lower mandible and to the bird's skull. [34] The muscles that depress the lower mandible are usually weak, except in a few birds such as the starlings (and the extinct Huia ), which have well-developed digastric muscles that aid in foraging by prying or ...
The brown pelican is the national bird of three Caribbean countries—Saint Kitts and Nevis, Barbados, and Sint Maarten—and features on their coats of arms. [136] [137] [138] It is also the state bird of the US state of Louisiana, which is known colloquially as the Pelican State; the bird appears on the state flag and state seal. [8]
A nose is a sensory organ and respiratory structure in vertebrates. It consists of a nasal cavity inside the head, and an external nose on the face. The external nose houses the nostrils, or nares, a pair of tubes providing airflow through the nose for respiration. Where the nostrils pass through the nasal cavity they widen, are known as nasal ...
The eyes and beak can be almost totally obscured by these fluffy head feathers. English budgerigars are typically more expensive than wild-type birds, and have a shorter life span of about seven to nine years. Breeders of English budgerigars show their birds at animal shows. Most captive budgerigars in the pet trade are more similar in size and ...
