Wading Bird Nesting Interval

Wading birds are an important indicator of foraging and nesting habitat quality, which itself is affected by nutrients and hydrology, similar to other indicators. Long-term hydrological patterns and nutrient impairment affect the distribution and composition of vegetation used for foraging and nesting, while short-term hydrology affects prey densities and predator access to colonies. Important wading birds in Lake Okeechobee are Great Egret, Snowy Egret, and White Ibis.

How is it measured?

Wading bird nesting interval is the mean interval between exceptional nesting years, which was based on a Greater Everglades Ecosystem performance measure that monitors the interval between exceptional nesting events for White Ibis. Exceptional years are defined as the 70th percentile of all nest abundance estimates in the period of record. The target value is any interval at least one standard error below the overall mean interval prior to the current reporting period. The calculations include data from three species; Great Egret, Snowy Egret, and White Ibis.
