Guadalupe Junco

Junco insularis

Endangered

It faces a very high risk of extinction in the wild in the near future. See full glossary

The Guadalupe junco is a bird endemic to a single Mexican island in the Pacific, Guadalupe Island, where it survives in the last stands of cypress and pine forest. Feral goats stripped the island's vegetation for more than a century, and their eradication in 2007 has allowed the forest and the junco to begin to recover.

Fun facts

  • The eradication of feral goats from Guadalupe Island in 2007, after more than a century of degradation, is one of the most ambitious island restoration projects in Latin America, and the cypress forest has begun to regenerate for the first time in generations.
  • The island lost several endemic species before that intervention, among them an owl and a kinglet of its own: the junco is one of the survivors.
  • Its total range is a fraction of an island of 250 square kilometres, which keeps it in the endangered category even though its population is counted in tens of thousands.
