Bird’s-eye view on World Environment Day

For World Environment Day today, we’re in northeastern Costa Rica, a nature lover’s paradise. The UN established World Environment Day in 1974 to encourage awareness and action for the protection of the environment. It begins with research, which is exactly what happens in this pristine corner of the planet. The misty canopy of the forest pictured here is part of La Selva Biological Station, an internationally renowned centre for tropical forest research that's associated with universities and research institutions from the United States, Costa Rica, and Puerto Rico.

The scientists chose a prime location to conduct their studies. Covering nearly 4,000 acres, this is one of the most biologically diverse ecosystems in the world. Researchers and students here at La Selva Biological Station can study at least 2,000 species of plants, 125 species of mammals, 87 species of reptiles, and tens of thousands of insects, arachnids, and other arthropods. And don’t forget the 470 species of birds. Can you spot the black-mandibled toucan in our image?
