Studies have suggested that there are both costs and benefits to aquaculturalists from egret predation (Ashkenazi and Yom-Tov 1996). Consequently, a critical conservation action is to expand surveys range-wide to identify, catalogue, preserve, protect, and manage important colony sites. Incubation period is 21-25 days. Adult and juvenile survival, rather than nesting success, is the most critical demographic parameter (Hafner et al. Dark birds are blue grey with a white throat, occasionally with white wing patches. It is distinguished from Cattle Egrets by longer, thinner, usually dark (not yellow) bill, black (not light) legs, slimmer body, longer neck, upright posture, and white (not buff) plumes. 1993, Fasola and Ruiz 1996, 1997).
