Northern ghost bats (Diclidurus albus) are solitary, rare and notoriously difficult to find. They prefer humid habitats like the areas around the lake and river in Carara national park wich is remarkable for its diversity because of its location in the transition zone between the southern rain forests and northern dry forests of Costa Rica. This female ghost bat was roosting about fifty feet up in a palm (long telephoto lens) and sheltering a tiny infant under her wings.
