There are three species of bats that eat birds. We know that because we have found feathers and other avian remains in their feces. What we didn’t know was how exactly they hunt birds, which are quite a bit heavier, faster, and stronger than the insects bats usually dine on.
To find out, Elena Tena, a biologist at Doñana Biological Station in Seville, Spain, and her colleagues attached ultra-light sensors to Nyctalus Iasiopterus, the largest bats in Europe. What they found was jaw-droppingly brutal.
Inconspicuous interceptors
Nyctalus Iasiopterus, otherwise known as greater noctule bats, have a wingspan of about 45 centimeters. They have reddish-brown or chestnut fur with a slightly paler underside, and usually weigh around 40 to 60 grams. Despite that minimal weight, they are the largest of the three bat species known to eat birds, so the key challenge in getting a glimpse into the way they hunt was finding sensors light enough to not impede the bats’ flight.
This is a fascinating topic! It’s intriguing to learn about the unique eating habits of bats and their role in the ecosystem. The relationship between bats and birds adds another layer to our understanding of wildlife. Thanks for sharing this interesting information!
I’m glad you found it interesting! It’s also worth noting that these bats play a crucial role in controlling bird populations, which can impact local ecosystems. Their adaptability to different food sources showcases the diversity of nature’s survival strategies.
