En: Galapagos Report 2011-2012 (2013), p. 174-179.Tema: The mangrove finch (Camarhynchus heliobates) is the rarest of 13 Darwin’s finch species endemic to the Galapagos Islands (Dvorak et al., 2004; Fessl et al., 2010). Currently classified as Critically Endangered by the IUCN, with an estimated population of 100 individuals, ongoing conservation management is essential to prevent extinction. Historically widespread throughout mangroves of Isabela and Fernandina (Dvorak et al. 2004), the mangrove finch is now restricted to 30 ha of mangroves in north-west Isabela at Playa Tortuga Negra (PTN) and Caleta Black (CB) (Figure 1). Until 2009 a remnant population was present south of Bahía Cartago; however, recent attempts to locate these birds have failed. Threats to the species include predation from introduced rats (Rattus rattus), nestling mortality through parasitism from introduced botflies (Philornis downsi), potential inbreeding through small population size, and environmental phenomena (tidal waves, volcanic uplift, etc.) destroying remaining habitat (Dvorak, 2004; Fessl et al., 2010). Effects of other introduced predators such as cats (Felis catus) and anis (Crotophaga ani) remain unknown (Fessl et al., 2010). Reasons for past declines are likely a combination of those listed (Fessl et al., 2011).
