A review of the introduced smooth-billed ani Crotophaga ani in Galapagos

摘要

The smooth-billed ani (Crotophaga ani) is a widespread introduced bird species in the biologically important archipelago of Galapagos. Many scientists and local people consider it to be a damaging invasive, and it is possible that it impacts native species and ecosystems via multiple mechanisms. However, evidence for this is largely anecdotal and research on smooth-billed anis in Galapagos is limited. Despite this, there have been repeated attempts to control or eradicate the population over the past few decades, all without long-term success. These attempts continue, but no official plan of action regarding this species currently exists.
