Crepúsculos: Guided tour and conversation around the ecology of bats

Crepúsculo Vernáculo

Event Slider

Thanks to the sophisticated echolocation system they use to fly and hunt in total darkness, bats are the undisputed kings of the night, both in nature and in the city. With 27 species, bats represent the most diverse group of mammals in Portuguese fauna but despite their importance to ecosystems and even to man, many of this species are currently threatened with extinction both in Portugal and around the world.

Researching the relationship between the figure of the vampire and the animal that served as reference, and establishing a bridge between art, science and biology, biologist Jorge Palmeirim invites us to discover reverberations, signs, and presences of bats in the gardens of the Calouste Gulbenkian Foundation.

On this visit we will dive into the fascinating aspects of the biology of these animals, watch bats manoeuvring in flight, listen to them echolocate using ultrasound converters, and talk about the sensory world in which these creatures live, so different to our own.
