|| Stephen J. Ambrose, Victor Fazio
A cumulative total of 47 waterbird species was observed at five small wetlands around Armidale,
northern New South Wales in 1985-86. Numbers of waterbirds peaked in March each year, with a
maximum count ot 3 074 in 1986, suggesting that these wetlands are importanl refuges at the end
of summer. Monthly and bi-monthly surveys indicated similar fluctuations in population sizes. However,
bi-monthly surveys decreased the detectability of vagrant species.
