About 7% of 340 adult vampire bats and 33% of 258 younger bats (<2 years of age) failed to feed on a given night. But when they do feed, wild vampire bats fill up like water balloons. Jon Flanders took this picture of a male vampire bat. He had originally caught this bat around the … Continue reading Foraging vampire bats can expect big meals or none at all
Talk: Cooperative food-sharing in the vampire bat Today! Monday August 31st @ 3 PM Location: Zoology Part II Lecture Theatre, Cambridge University, Downing Street, Cambridge, UK CB2 3EJ Map Thanks to Neeltje for organizing this talk.

There's an obvious benefit to her: bats with larger sharing networks are more successful at getting fed. But there’s potentially a more subtle benefit.

The smaller image shows one adult female greater spear-nosed bat (Phyllostomus hastatus) left behind with several pups unrelated to her. Both these images … Continue reading Crèches in bats and the ‘huddler’s dilemma’
