英文摘要	Nomadism is a type of movement lacking fixed spatiotemporal patterns, evident in species inhabiting variable environments. The irregular movement characterizing nomadic species often acts as a challenging barrier for scientists investigating their ecology. We provide an insight on the movement of a nomadic desert bird, the Spotted Sandgrouse (Pterocles senegallus), within and between different activity seasons. The data were obtained from 1 individual fitted with a satellite transmitter, which was tracked for similar to 2.5 years. Three main activity seasons were detected during which the bird stayed in a specific area: pre-breeding, breeding, and winter. Nomadic behavior was evident during the pre-breeding and breeding seasons, whereas site fidelity was observed during winter (i.e., seasonal nomadism). Local scale fidelity with respect to roosting behavior was also evident among and within the 3 winters of tracking. Field observations carried out during the first breeding season enabled us to link the movement patterns of the bird with its behavior at different phases of the breeding season. Within and between activity seasons, the bird was engaged in short- and long-distance scouting forays. The long-distance ones occurred only during the pre-breeding season. In some of the scouting forays, the bird arrived at sites it had previously utilized, suggesting the existence of spatial memory and navigation capability. This fine-scale description of movement can uncover key features, which allow the survival and reproduction of nomadic birds inhabiting arid areas where the distribution of resources is largely unpredictable.
