Range DescriptionIcterus northropi was recently split from I. dominicensis following studies into the morphology, life history, vocalisations and genetics of the dominicensis group (Price and Hayes 2009, Sturge et al. 2009). It is endemic to the Andros group in The Bahamas, including North Andros, South Andros and Mangrove Cay. It formerly occurred on Abaco, but disappeared for unknown reasons in the early 1990s (M. Price in litt. 2010, 2011). In 1997, a "liberal" estimate was put forward of 150-300 individuals on North Andros and South Andros (Price and Hayes 2009); however, more recent surveys recorded a total of 81 individuals on North Andros, 22 on Mangrove Cay, and 24 on South Andros. Assuming 50-100% detectability, total numbers are estimated at 127-254 (M. Price in litt. 2010, 2011). These surveys did not extend to the interior (pine forest) and western side (mangrove) of Andros; however, the species is thought to be rare in these habitats (Currie et al. 2005, M. Price in litt. 2010, 2011, W. K. Hayes in litt. 2011). Habitat on Wood Cay may be suitable, but other cays within and around Andros are thought likely to be too small to support populations. Initial results of a genetic study suggest that the species has one subpopulation, as there is some movement between islands (M. Price in litt. 2010, 2011).
