Description:

Movement patterns and survival estimates of Blue Cranes in the Western Cape.

Summary / Notes:

The Western Cape population of Blue Cranes Anthropoides paradiseus is the species’ largest and most stable population. How this population utilises the agricultural landscape of the Western Cape, how far individuals disperse and the connectivity between subpopulations is unknown. Basic demographic parameters such as survival are also understudied. We explored movement patterns and survival using a long-term data set of 649 individually-marked birds. Resightings suggest that movements in the Western Cape were localised, with an average displacement of 24.6 km from their natal point. Displacement varied with age but not season. Despite regional differences in resighting effort, only 3.8% of individuals were observed in both the Overberg and the Swartland, suggesting high regional fidelity. However, there was significant movement within the Overberg, so Blue Cranes appear to be resident to locally nomadic in the Western Cape. There was evidence that adults return to their natal site: 57% of adults were resighted in the area where they were ringed as chicks. The viability of Blue Cranes therefore depends on correct local management. Mark–recapture survival estimates were 0.6 for juveniles, 0.87 for immatures, and 0.72 for adults, although adult survival was underestimated due to ring loss. Future studies should use a different ringing technique. Keywords: Blue Cranes, movement, ring loss, survival, Western Cape.
