| Résumé : | A census conducted in July 2017 at Bessans (Savoie, French Alps) by series of transects with distance measurements allowed to assess the number of Whinchats present on a surface area of 200 ha of meadows at an altitude of 1700 m a.s.l. At least 56 singing individuals (minimum single count) and 64 singing individuals (41-95 in the 95% confidence interval) were counted through distance-sampling data processing. Thus the density was of 3.2 pairs/10 ha or 32 pairs/km(21-48) which places this site among the richest one in France for this highly threatened species. |
