“The increased availability of food and nesting habitat for the Azores bullfinch led to a gradual increase in the bird’s numbers. In 2010, with a population estimate of about 1,000 birds, IUCN downlisted the species to ‘endangered.’ In 2016, the organization downlisted the bird again to ‘vulnerable.’ The current population size of the Azores bullfinch is estimated to be around 1,300 individuals distributed across nearly 5,000 acres of suitable habitat in the Pico da Vara/Ribeira do Guilherme area.”
