Observatoire des Bourdons aims to obtain qualitative and quantitative data on bumblebees to better understand the impact of global changes on these pollinating insects.

Specific actions

Participants carry out inventories of bumblebees in their gardens or on their balconies, noting the maximum number of individuals seen together for each species. At the end of each week of observation, the data are entered on the observatory website.

Project description

This observatory is part of the Vigie Nature network.


Observatoire des Bourdons was co-founded in 2009 by the Groupe Associatif Estuaire (GAE) and the Muséum national d’histoire naturelle to study bumblebee populations and their trends. The observatory is a citizen science program for the general public. You can contribute alongside other community members by counting bumblebees in your garden. Bumblebees can be observed over one or several weeks depending on your availability. If possible, try to spend at least 10 consecutive minutes once or several times a week counting the bumblebees in your garden. You can then enter the data each month on the observatory website. You should note only the maximum number of individuals for any color pattern seen simultaneously over one week of observation.
