Egestion/Consumption ratio (E/C) = 0.35
dry weight/wet weight ratio (dw/ww) = 0.35
gramms of carbon/gramms of dry weight = 0.45
Biomass per bird = 2390 g (wet weight)
Dry season = 2.40E-07 birds / m2
Wet Season = 8.06E-08 birds / m2
*Because wading birds seem to be underestimated compared to woodstork biomass in the Browder thesis, we tripled the number of birds in the above reference
