In this study, we tracked the movements of Black Coucals Centropus grillii breeding in Nigeria from late July using satellite telemetry. Individuals remained on the breeding site for several months; two individuals transmitted after October and these two moved shorter distances (< 100 km) away from the breeding site in early December. One of these was tracked for a full year, moving to a site 175 km south of the breeding site in early January and returning to the breeding site in late May. The bird migrated faster during the return journey (58 km day−1) as compared to the post-breeding journey (5.9 km day−1). The overall home range (90% kernel density) during breeding was 20.4 ± 3.3 km2 (mean ± s.d.) and the core (50%) 5.0 ± 1.6 km2 with no apparent clear change outside of the breeding season. Vegetation conditions at the distant site were apparently poorer although in an average year the move would have led to improved conditions.
