Description : The Great Egret is a large, white waterbird with a large pointed bill (adult bird length approximately 91 cm, wing 35 cm, bill 10 cm, tarsus 17 cm, tail 13 cm). The male is larger than the female. The breeding adult looks white overall with a blackish bill. The non-breeding adult lacks neck plumes. It feeds on fish, frogs, molluscs and aquatic insects. The great egret is a highly successful species with a wide distribution across temperate and tropical habitats worldwide. It forms breeding colonies near large lakes with reed beds or expansive wetlands, preferably at an elevation of 10-40 feet (3.0-12.2 m). Breeding begins at 2-3 years of age, with monogamous pairs forming each season, although it is unclear if the pairs stay together in subsequent seasons. The male chooses the nesting area, constructs the nest using sticks and plant material, which can be as large as 3 feet across, and attracts a female. A clutch of up to six bluish-green eggs is laid at once. Both parents take turns incubating the eggs, which hatch after a period of 23-26 days. The young are fed through regurgitation by both parents and become capable of flight within 6-7 weeks.
