Cherief-Boutera, N., Bensaci, E., Cherief, A., & Moali, A. 2013. Première preuve de reproduction du Goéland railleur Chroicocephalus genei en Algérie. Alauda 81: 85-90.
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.
