Did you know…?

• It is one of the few birds occupying the páramo of the Costa Rican summits, an environment that exists only above 3,000 metres and that in Central America is limited to a handful of massifs.

  From

• It is extraordinarily trusting with people: it comes up to the mountain huts and to walkers on Chirripó looking for scraps, behaviour typical of birds that evolved without land predators.

  From

• Its bright yellow eyes against dull plumage make it unmistakable: no other bird on those summits has them.

  From

• Its geographical forms are so different that until 1973 they were classified as five or six separate species, and numerous subspecies with very different plumages are still recognised today.

  From

• There are estimated to be more than six hundred million individuals, which places it among the most abundant land birds in North America.

  From

• The population that colonised the campus of the University of California, San Diego in the 1980s has developed measurable changes in behaviour and morphology within a few decades, and is a case study in rapid urban evolution.

  From

• 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.
