Woodcreepers (Dendrocolaptidae)
Ivory-billed Woodcreeper (Xiphorhynchus flavigaster) - HBW 8, p. 432
French: Grimpar à bec ivoire
German: Strichelbaumsteiger
Spanish: Trepatroncos Picomarfil
Other common names: Laughing Woodcreeper; Stripe-throated Woodcreeper (“striatigularis”)
Taxonomy: Xiphorhynchus flavigaster Swainson, 1827, Temascaltepec, México, Mexico.
Sister-species relationship with X. lachrymosus has been suggested on basis of molecular data. Assessment of geographic variation is complicated by marked individual variation in coloration, overall size, and pattern of streaking (width and shape) both above and below. Race mentalis poorly differentiated from nominate; saltuarius, ascensor and ultimus weakly differentiated from eburneirostris. Described form striatigularis, known from unique type specimen from S Tamaulipas (Mexico), sometimes treated as a full species, but recently shown to rep.. View all taxonomy...
Sister-species relationship with X. lachrymosus has been suggested on basis of molecular data. Assessment of geographic variation is complicated by marked individual variation in coloration, overall size, and pattern of streaking (width and shape) both above and below. Race mentalis poorly differentiated from nominate; saltuarius, ascensor and ultimus weakly differentiated from eburneirostris. Described form striatigularis, known from unique type specimen from S Tamaulipas (Mexico), sometimes treated as a full species, but recently shown to represent an aberrant individual of present species. Eight subspecies recognized.
Subspecies and Distribution:
- tardus Bangs & J. L. Peters, 1928 - NW Mexico (SE Sonora, N Sinaloa); intergrading with race mentalis in W Durango.
- mentalis (Lawrence, 1867) - Coastal W Mexico (C & S Sinaloa S to Michoacán); intergrades with tardus in W Durango and with nominate in W Guerrero.
- flavigaster Swainson, 1827 - SW Mexico (Guerrero, S Oaxaca).
- tardus Bangs & J. L. Peters, 1928 - NW Mexico (SE Sonora, N Sinaloa); intergrading with race mentalis in W Durango.
- mentalis (Lawrence, 1867) - Coastal W Mexico (C & S Sinaloa S to Michoacán); intergrades with tardus in W Durango and with nominate in W Guerrero.
- flavigaster Swainson, 1827 - SW Mexico (Guerrero, S Oaxaca).
- saltuarius Wetmore, 1942 - NE Mexico (S Tamaulipas and SE San Luis Potosí S to N Veracruz).
- ascensor Wetmore & Parkes, 1962 - Caribbean slope of S Mexico from S Veracruz and N Oaxaca E to Tabasco, possibly also N Chiapas E to adjacent Guatemala.
- yucatanensis Ridgway, 1909 - Yucatán Peninsula; populations at base of peninsula S to N Belize, possibly to NC Guatemala (Petén), show signs of intergradation with eburneirostris.
- eburneirostris (Des Murs, 1847) - Caribbean Slope of Central America from C Guatemala and Belize E to Honduras, also locally in N Costa Rica; Pacific slope from S Mexico (extreme SE Oaxaca, S Chiapas) S to NW Costa Rica.
- ultimus Bangs & Griscom, 1932 - hills of Nicoya Peninsula, in NW Costa Rica; possibly intergrading with eburneirostris in adjacent lowlands.
