The conservation status of the Galapagos Martin is rated as Vulnerable (BirdLife International 2010). The range of the species is small, and although the total population size is not known, the population is believed to be in decline. The total population is estimated as less than 1000 individuals (BirdLife International 2010).
Effects of human activity on populations
The causes of apparent populations declines in the Galapagos Martin have not been established, but the introduction to the Galapagos Archipelago by humans of predators (such as rats Rattus) and parasites (such as the botfly Philornis downsi) are suspected of playing a role (BirdLife International 2010).
