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.
