In 2014 and 2016, I traveled to Kenya to sample a broad range of bat species for microbial symbionts and malaria-like haemosporidian parasites. During these trips, I was able to sample over 30 species of bats with Dr. Paul Webala and his students (see MSc student Beryl Makori's work here!). Little is known about symbionts or haemosporidian diversity in east African bats, so our surveys targeted a variety of habitats, from the coral coasts near Arabuko-Sokoke to the open dry savannah of Ol Jogi Wildlife Conservancy in Laikipia County, to the lush and chilly rainforest of Kakamega in the west, and down into a variety of caves, mines, buildings and outhouses. This work has already produced novel insights into the evolution of malarial parasites in vertebrate hosts, and we are just scratching the surface of microbial diversity in these amazing animals.

Among many collaborations between the Kenya Wildlife Service, National Museums of Kenya, and Field Museum of Natural History, the Bats of Kenya Project has emerged as a promising effort to scientifically document chiropteran diversity in Kenya. In addition to documenting species throughout Kenya, scientists working on this project are collecting data on echolocation calls, parasites, and pathogens.
Paul has worked closely with communities throughout Kenya. Here he is pictured with Ms. Beatrice Amadalo, who has been awarded a certificate of recognition as a "Bat Guardian" by the IUCN Species Survival Commission. Beatrice runs a farm that serves as the roosting site for a large colony containing many thousands of Straw-coloured fruit bats (Eidolon helvum). Allowing such a large colony of bats to roost safely over crops comes at a great financial cost to local farmers. It is not only economically costly, but can be torturously loud as well (just listen to the video below!). We owe great thanks to men and women like Beatrice and her husband who struggle under the weight of such sacrifices.

Footage of some rowdy Eidolon helvum I captured on Beatrice's land. We sampled and released quite a few of these guys for blood parasites...they are not only loud, but unruly in the hand as well...
