A photo of two Galapagos Mockingbirds chasing after water on the Galapagos Islands, Ecuador. These birds can sense water from far away due to the fact that there is no fresh water on the Galapagos Islands, save one island.
The Floreana mockingbird is listed as Endangered on the IUCN Red List.
The small populations of the Floreana species are especially affected by El
Niño cycles, which cause significant changes in population size. Global
warming may increase the occurrence and severity of these cycles.
The extinction of Floreana mockingbirds on the main island is likely to be
due to a combination of factors. It has been associated with the loss of
Opuntia cacti, which were destroyed by invasive goats, donkeys and pigs
and are now very rare on this island.
Predatory cats and black rats that eat mockingbird eggs are likely to have
affected mockingbird populations. The smooth-billed ani is an introduced
bird that preys on nestlings including mockingbirds. Parasitic Philornis
flies have been found in mockingbird nests, affecting nestling survival.
San Cristóbal mockingbird populations are declining within their
restricted range on a single island. This species is listed as Endangered on
the IUCN Red List. The Española species is listed as Vulnerable due to its
restricted range. Habitat degradation and the impact of invasive species
and climatic events continue to threaten these species.
Like other Galapagos birds, mockingbirds are susceptible to introduced
avian diseases, such as avian pox. Avian pox was introduced with bird
species brought to the islands, including poultry. In the future, avian
malaria and West Nile virus infection may also become a problem.
