The Swan Islands (part of Honduras) lie in the Caribbean c.200 km due north of Laguna Caratasca in easternmost Honduras and 325 km south-west of Grand Cayman in the West Indies. They comprise two main islands, Big Swan (c.6 km²) and Little Swan, and have been identified as a Secondary Area due to the presence of Vitelline Warbler Dendroica vitellina; this, the islands' only resident passerine, occurs also on the Cayman Islands (Secondary Area s014). The population on the Swan Islands constitutes an endemic subspecies, nelsoni, and is (or was in the 1960s) common on both islands. Five species of landbird (including D. vitellina) have been reported breeding on the islands, including the now locally extinct Red-legged Thrush Momocichla plumbea. The islands also support a mixed seabird colony including Red-footed Booby Sula sula, Brown Booby S. leucogaster and Magnificent Frigatebird Fregata magnificens (Monroe 1968).
