Distribution of the 4 endemic mockingbirds
|
Notes:
- Nesomimus parvulus includes 8 described subpecies. The other three species are monotypic.
- Within the area indicated, Nesomimus 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
- Pending molecular phylogenetic analysis suggests that N. parvulus bauri, the Genovesa (Tower Island) Mockingbird, could be a distinct species more closely related to N. trifasciatus and N. melanotis than to N. parvulus (Arbogast et al. 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
