Fregata minor magnificens

Mathews

, 1914,

Santa Fe Island, Galapagos Archipelago

.

Formerly included in F. aquila or sometimes in F. minor. Galapagos population has been suggested to merit treatment as a separate species, on basis of morphological and genetic data#R; at the other extreme, races lowei and rothschildi, supposedly separable on length of wing, tail or bill, have commonly not been accepted; further study required. Three subspecies currently recognized.

Subspecies and Distribution
  • F. m. rothschildi Mathews, 1915 – islands off America, on Pacific coast from NW Mexico (Baja California) to Ecuador, and on Atlantic coast from Florida to S Brazil.
  • F. m. magnificens Mathews, 1914 – Galapagos Is.
  • F. m. lowei Bannerman, 1927 – Cape Verde Is, in E Atlantic Ocean.
