Abstract:
First confirmed breeding of the Slender-billed Gull Chroicocephalus genei in Algeria.
A colony of Slender-billed Gull was surveyed during the spring of 2010 at El-Kerfa (High central plateaux of northern Algeria). 422 nests were counted on an islet and the clutch size was of 2.8 eggs per nest. A sample of eggs were measured and weighed. The high rate of successful hatching (98.81 %) was attributed to the high quality of habitat (undisturbed area, good food availability). The monitoring of this breeding site will be carried out in the future.
