A new instance of bats enjoying human blood has surfaced in Brazil. Scientists examining local bat diets found the blood is the life indeed:
Researchers from the Universidade Federal de Pernambuco found evidence of human-blood consumption in hairy-legged vampire bats (Diphylla ecaudata)... Our results suggest that the diet of D. ecaudata is more flexible than expected.
These bats are known for feeding on bird blood, so the presence of human blood as seen in a DNA analysis of bat feces was a surprise. "This species isn't adapted to feed on the blood of mammals," researcher Enrico Bernard told New Scientist.
We at Infocult approve of the researchers' next steps: "Bernard and his team are now looking into how the bats access humans at night, whether it's by finding people sleeping outside or by entering homes."
