rare bird, a idiom
An exceptional individual, a unique person, as in That wife of yours is a rare bird; you're lucky to have her. This idiom, generally used as a compliment, is a translation of the Latin rara avis, which itself was used from about 1600 on and began to be translated only in the late 1800s.
