Telemetric monitoring of Northern Gannets

Objectives and methodology

The objective of the measure is to improve knowledge of the ecology of the Northern Gannet in the Bay of Saint-Brieuc. This monitoring is not intended to replace the actions already carried out in the area, but to complement them in order to refine knowledge about the local colonies.

Fieldwork will take place in Sept-Iles, but the data collected will allow detailed monitoring of their movements and fishing activities throughout the Channel.

Adult Northern Gannets will be captured in Sept-Iles during the breeding season. They will be equipped with the latest generation of electronic devices allowing detailed monitoring of their movements on a small and large scale, their flight altitudes and their frequentation of the project area. This equipment will consist of 15 GPS recorders, 20 geolocators, 10 altimeters and 10 miniaturized on-board cameras.

This measure will be implemented through close collaboration between the Sept-Iles nature reserve and the CNRS. This collaboration, which has been in place for several years, has made it possible to validate and refine all of the protocols that will be used for this work, as well as all of the logistical modalities.

Location of actions

The capture and departure of Northern Gannets will be carried out within the Sept-Iles reserve.

Under development

Monitoring will take place over three years:

  • One year in the construction phase (2023) 0% 0%
  • two years in operation (2024-2025) 0% 0%

Each year, monitoring will take place over a three-month period, which includes two and a half weeks of data collection on Sept-Iles Northern Gannets (June) and two and a half months of preparation of fieldwork, data analysis and writing of the annual report (June - July - August).
