Tropical Biology in Costa Rica

Leith and I just arrived in Costa Rica for a field course in Tropical biology with the Organization for Tropical Studies (OTS). Our first stop is Palo Verde, a dry tropical forest that is a unique habitat.  Here with the Organization of Tropical Studies (OTS) course, we are observing an incredible diversity of wildlife from longhorn beetles (Cerambycidae), to the frog-eating bat, Trachops cirrhosus, to the Limpkin, Aramus guarauna. Drawing inspiration from this mega-diverse ecosystem, we are carrying out research projects, learning cutting edge research techniques, and squeezing a little time in for fun too.

If you would like to keep up with our progress visit our course website.  We upload a science minute podcast daily and blog about our progress overall on the course.

Notes from the field: Ectophylla alba

Ectophylla alba, the Honduran white bat, is a unique species of Neotropical leaf-nosed bat. Not only they are among the very few species of bats that are almost completely white, but they are extremely specialized in their diets and roosting ecology. Males and females of the species skillfully construct delicate tents from the leaves of Heliconia plants, and their diet is restricted to fruits of Ficus colubrinae plants. During our most recent trip to Costa Rica, we had the opportunity to record and measure these bats as they frantically fed from a F. colubrinae fruiting tree (below). Fruiting events in Ficus plants occur in short bursts and are scattered throughout the landscape, and E. alba likely choose places to “camp out” according to the potential for food availability.
