macqueenii

Macqueenii is a Latinized patronym used as a species epithet in the scientific names of several organisms to honor a person named Macqueen. In binomial nomenclature, macqueenii is the lowercase genitive form derived from Macqueen, with the suffix -ii indicating a masculine honoree.

The best-known usage is Chlamydotis macqueenii, commonly called Macqueen's bustard, a large ground-dwelling bird of the bustard family (Otididae). It inhabits arid and semi-arid regions from the Middle East to Central Asia, favoring desert steppe and open grassland. The species is known for cryptic coloration and display flights by males during courtship.

Beyond birds, macqueenii appears in other genera as a patronym commemorating a Macqueen who contributed to natural history, though the specific individual varies by source. The epithet illustrates how scientists honor collectors and researchers in taxonomy, linking modern names with historical figures.
