Distribution of the 4 endemic mockingbirds
- Mimus parvulus includes 8 described subpecies. The other three species are monotypic.
- Within the area indicated, Mimus parvulus occupies all large islets, and some smaller islets, with some notable exceptions:
- Pinzón (Duncan): wiped out by introduced black rats before ever observed (Curry 1986)?
- Baltra (South Seymour): driven to extinction by direct or indirect human activity during World War II, when Baltra was transformed into an American military base and airfield
- Daphne Major: only 1 individual detected in > 30 years of intensive field study of finches
- Recent phylogenetic analysis suggests that M. parvulus bauri, the Genovesa (Tower Island) Mockingbird, could be a distinct species more closely related to M. macdonaldi and M. melanotis than to N. parvulus (Arbogast et al. 2006). However, work in progress using microsatellite DNA also suggests that the Genovesa population could have derived from hybridization between a population allied with M. parvulus and individuals from the M. macdonaldi population (P. Hoeck and L. Keller, in preparation).
- The Floreana Mockingbird persists only on two small islets, Champion and Gardner-by-Floreana (not to be confused with Gardner-by-Española). More
