Click and Count — photographic estimates of bat populations at caves

Of the various methods used to estimate bat colony size, photography is currently one of the least explored. The potential advantages of using photography, however, are numerous, particularly for colonies with high numbers of individuals. This paper describes how the authors used photographs to estimate bat roosting density in the world’s largest colony of Geoffrey’s Rousette fruit bat on Samal Island, Philippines. Colony density was highly variable and possibly influenced by physical features of the cave and circadian rhythms of the bats. The methods outlined in this study provide a basis for reliable population estimates that will be vital to conservation efforts.

To continue from the great work done at the Cambodian FF workshop, the roost count data sheets and protocols, along with the disease guidelines have now all been translated into Indonesian. They are now available in the resources section. Thanks to Sheherazade and Felicia Lasmana for their work on it!
