First breeding data on the Black-headed Gull Chroicocephalus ridibundus in Central West Morocco.
This study presents the first data on a breeding colony of the Black-headed Gull on islets of the Al Massira reservoir in central west Morocco from 2002 to 2008. Laying phenology, nesting site selection, clutch size, egg size and breeding success were investigated. These data provide new information at the southwestern limit of the species’ breeding area (32° N).

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.
