Family : Ardeidae
Order : Pelecaniformes
Class : Aves
Phylum : Chordata
Other Name : Little Heron, Little Green Heron
Habitat : Wetlands
Description : The Striated Heron is a small greenish wader (adult bird length approximately 46 cm, weight 220 g, wing 18.8 cm, bill 6.5 cm, tarsus 4.8 cm, tail 6 cm). It has a dark greenish upperpart with white fringes to the wing feathers. It has a grey head and neck. It eats small fish, crustaceans, amphibians, insects and other edible tidbits. It is more active at dawn and dusk. It breeds in March and July. They construct nests made of sticks, typically measuring 20-40 cm long and 0.5-5 mm thick. The nests are about 40-50 cm wide and 8-10 cm high on the outside, with an inner depression about 20 cm wide and 4-5 cm deep. They are usually built in shrubs or trees, sometimes on the ground, and are often located near water. The clutch consists of 2-5 pale blue eggs, measuring approximately 36 by 28 mm.

There have been observations of an adult bird engaging in a mysterious behavior where it rapidly moves a stick back and forth while on the nest, similar to a sewing machine's needle. The purpose of this behavior remains unknown, as it does not seem to serve the usual functions of nest compacting, egg movement, or parasite removal seen in other nesting birds.

When young cattle egrets feel threatened, they display a behavior of stretching out their necks and pointing their bills skyward. However, the effectiveness of this display in deterring predators is uncertain.
