Tete - grey teal - Anas gracilus
Photographed on Lake Ellesmere, Canterbury, New Zealand.
The grey teal is a small dabbling duck that frequents shallow freshwater lakes. The bird is extremely nomadic. This nomadic way of life enables the bird to quickly exploit shallow temporary water during irregular flooding in the interior of Australia. The grey teal was self-introduced to New Zealand from Australia from irregular irruptions. The last major irruption occurred in 1957 following drought conditions in Australia. Pair-bonds appear to be retained from one season to the next - www.nzbirdsonline.org.nz
