A member of the B. brachyurus clade (which see). Formerly thought to be most closely related to Geranoaetus albicaudatus. Several recent molecular studies, however, indicate that present species and B. swainsoni are sister-taxa#R#R#R#R; diverged only very recently from B. swainsoni and colonized Galapagos Is through a single event#R. Recent analyses revealed that galapagoensis had highest levels of genetic uniformity found in any natural bird population, with degree of uniformity strongly influenced by island size, and high levels of genetic similarity between geographically proximate island populations#R. Monotypic.
