1000th observation passed!

Today, the AfriBats-project passed its 1000th observation with a beautiful series of long-term observations of a family of Mauritian tomb bats (Taphozous mauritianus) by Martin Grimm from Tanzania.

Since the last collection of highlights, there's been a fantastic and increasing number of bat observations from around Africa, Madagascar and smaller islands. Some were obtained during dedicated research projects while a large number was contributed by interested citizen scientists.

Jack Bradbury, of Hypsignathus-fame, shared some of his historic bat observations from Gabon, which date back to the 1970ies and which were taken during a time when technology was far less advanced than today. Hard to imagine the serious constraints to bat research ...more ↓

This is Eric, the same individual posted on the 9th of February 2015, now trying to practice flying and growing very well on a diet of pasteurised milk and banana, with some variation of guava and mango.
He tries wild figs but does not seem able to break into them.
Radius is now 8.7 cm and body weight of 100 g (+/- 10g)!

Identification of these small Epomophorus bats in Kasanka is a bit tricky: they clearly belong to the crypturus/labiatus/minimus group based on the pattern of the palatal ridges. Morphometrically, they agree with what Bergmans & van Strien (2004) identified as "E. cf. labiatus" from Malawi, and are smaller than E. crypturus, E. angolensis, and E. anselli.

However, these small Epomophorus would also agree in measurements with what was previously called E. minor, and what is now generally accepted as E. minimus. The latter species is currently assumed to range from Ethiopia to East Africa, with no records near Kasanka NP. Based on distribution, Kasanka specimens are tentatively referred to E. labiatus.

About

The bat fauna of Africa and surrounding islands boasts ~ 300 species, but the distributions of many species are poorly known. Despite the crucial role of bats (Chiroptera) as pollinators and seed dispersers of plants as well as predators of insects, one-fifth of the bat species in Africa are threatened, and populations are declining due to habitat loss, disturbance and destruction of roost ...more ↓
