This work describes the migration and breeding biology of the Stone-Curlew along the coast of NW Morocco. Spring departure occurred in the first half of April. Stone-Curlews established their nests in banks of soft sand, soft sand with blocks of sandstone and meadows covered with stones. Clutch-size was similar to that of European populations but not egg-volume. No significant differences were found in egg-volume between years. Laying took place between the second half of March and the end of May. Clutch desertion (40%) and trampling (20%) were the main causes of nest-failure. Average hatching success over the whole study was 70.6% (n=17) and the average number of chicks hatched per nest was 1.82±0.09. In the Moroccan Atlantic shore study area, Stone-Curlews are affected by significant disturbance from human activities, mainly leisure and tourism; therefore conservation measures need to be taken in order to maintain the population.
