To better understand how to face to the recurring nuisances caused by the numerous crows in Paris, a study was set up by the National Museum of Natural History at the request of the city's environmental services since July 2015.

It's about capturing and tagging crows, to study their movements and survival.
At the beginning of 2022, more than 900 crows have been captured in Paris and fitted with colour rings with a 3-digit code which allows them to be identified when they are relocated. Each year, the general public and ornithologists communicate to the museum 24071 relocations of ringed individuals, especially in Paris and the close suburbs, but also at longer distances.

This website was created to allow observers to report their observations of colour-ringed crows, and to provide access to the history of each ringed bird. You can thus consult the different observations of a bird, by visualizing its places of observation on a map.

Good observations, beautiful explorations and good crows!
