Summary:
The purpose of this research was to quantify wading bird hourly and daily foraging activity in a drying wetland. We sought to determine the hours of peak activity and identify water depths that facilitate high foraging activity. Our results indicated that 56% of daily activity occurred between 0600 – 0800 h and >95% of the daily activity was found in images taken between 0600 and 1400 h. The wading bird activity showed little variation and no obvious correlation with water depth fluctuations (highest recorded density = 2.1 birds/ha at 14.9 cm depth; lowest recorded density = 0.05 birds/ha at 35.1 cm depth). The wading bird activity occurring between 0600 – 1400 h accounts for >95% of daily activity. We conclude that a study of water depth and average wading bird density earlier in the nesting season is needed for a clearer effect of water depth on wading bird foraging activity.
