Bird Population Study at Le Bosquet — 2004

An ornithological project in cooperation with Jean Collette and GONm.

In 2004 Jean Collette of the Groupe Ornithologique Normand (GONm) kindly agreed to select our tiny farm in the Norman Bocage as a site for a long-term study of its permanent, seasonal and migratory bird population. By carefully noting any changes in the immediate and adjacent environment, we hope that from regular censuses over a period of time we may learn more about our resident and visiting bird populations. (See also Small Farm Structures in the Bocage Virois.)

We are extremely grateful to Jean 'William' Collette for his constant help, advice and regular visits to compile the census information which appears below. When he began his monthly visits in 2004, we were sufficiently impressed by the numbers of birds he was able to identify. By 2006 we were astonished to find him recording, flora, fauna and fungi in extraordinary detail. "Merci, cher William! Quel travail, quelle diligence, quel bonheur!".

For the fullest information from these censuses, please click on the small graphics to see the detailed analysis and the consistency and frequency statistics for each species.

La constance est le rapport, exprimé en %, entre le nombre de visites où une espèce est notée et le nombre total de visites. Exemple: une espèce vue au cours de la moitié des relevés a une constance de 50%.
La fréquence est le rapport, exprimé en %, entre le nombre d'individus d'une espèce, comptés au cours d'une sortie, et le nombre total d'oiseaux comptés au cours de cette visite. Exemple: 100 oiseaux, toutes espèces confondues, ont été comptés au cours d'une visite. Le merle qui est représenté par exemple par 30 individus, est caractérisé par une fréquence de 30% au cours de cette visite.
