The first in a series of environmental field recordings, here's a 10-minute glimpse into typical Costa Rican night ambience. Although Costa Rica only makes up about 0.1% of the Earth's landmass, it contains about 5% of our planet's biodiversity. Covered in rainforests, the wealth of plants, animals and insects here can be overwhelming to any city-dweller. Dare I say the nights here are louder than those in America's urban areas due to all the nocturnal critters that emerge. Featured prominently in this segment are the Tink Frogs (Eleutherodactylus diastema), who's ubuitous call has a punctuated electronic or metallic quality. At night, you are immersed in a soundscape of countless numbers of these vocal amphibians. This is a binaural recording and headphone listening is recommended.
