The Namibia Crane Working Group, an initiative of the Namibia Nature Foundation, has been monitoring this crane population since 2004, mainly by means of regular counts in the wet and the dry season. More than 30 chicks have been fitted with large green plastic rings, each of which bears a unique alphabetical code. Resightings of these ringed birds contribute to the recording of crane distribution, movements and breeding activity. Birdwatchers and other visitors to Etosha make an invaluable contribution by reporting ringed cranes, nests, chicks and numbers, and by submitting some wonderful photographs.
