Abstract

Potential relationship between meteorological conditions and the timing and path of Cattle Egret migration from colonies in the Hunter Valley (NSW) to locations in Victoria, Tasmania and New Zealand were investigated for the period 1987-1989. Meteorological maps obtained for a period of up to five days previous to known movement dates were analysed to identify possible migration paths. Three potential outward and two potential return paths were identified which make use of wind-flows around high and low systems. The results show that Cattle Egrets may well utilise weather systems in their migration and point to the need for further research for clarification.
