WARNING! On July 27th and August 10th, scheduled interventions will be carried out on the electrical connection in order to improve the infrastructure, although no impact on services is expected.

Bat Monitoring Programme

Citizen science programme to monitor bat populations

 ChiroHabitats

Monitoring of bat species in all kind of habitats using passive acoustic monitoring.

 ChiroRivers

Monitoring of bat species present in aquatic ecosystems, used as ecological Indicators of water and riparian forest quality.

 ChiroBoxes

Monitoring of bat species that use artificial roosts such as bat boxes.

 ChiroRoosts

Monitoring of bat colonies in natural or artificial roosts such as caves, mines, tunnels, churches or buildings.

 ChiroCaptures

Data collected during capture sessions using mist-nets, harp-traps, hand-nets or direct captures in roosts.

Do you want to start using this platform and you have a great amount of data you would like to add to the project?


Massive data import

Advanced Working Groups

Do you want to go one step further in the conservation of bats and contribute to the specific monitoring of threatened species? The Working Groups make it possible to obtain long-term trends in the populations of different bat species of interest.

Send us your sightings!

If you find a bat at home or grounded, or you identify it through your acoustic detectors, do not hesitate to send us your observation! But if you find the bat in a nest-box or a bat-box, or you find a bat colony or an individual in which could be a potential roosting site, it is better that you sign up in our website and enter the information in the ChiroBoxes and ChiroRoosts sections respectively!

This information is crucial to complement the distribution data of the different species all around Europe. Take a picture or send us the recording so we can identify it. Thank you so much!
