In mаle lаzuli buntings (Pаsserina amоena), a bird species that is native tо Nоrth America, the feather coloration of males ranges from dull brown to very bright blue. Interestingly, it is the dullest and brightest yearlings that are most successful in obtaining high quality territory in a habitat with limited nesting sites. Adult males seem to tolerate dull-colored yearlings, who are perceived as non-threatening, and also keep distance from brightly colored yearlings. Yearling males with intermediate plumage are attacked by adults and therefore fail to obtain territory and attract females.

A curved red blood vessel wraps around the lower part of the alveolus and contains small red circular cells representing red blood cells. Four parts are labeled: A marks the narrow upper passage leading into the alveolus. B labels the large central air space inside the alveolus. C is placed over the red blood vessel, which carries red blood cells along the outside of the alveolus. D is positioned over the thin boundary where the wall of the alveolus meets the wall of the blood vessel.
