Cochoa viridis

Green Cochoa, also known as Green Cochoa, is a bird of the family Thrushidae in the order Passeriformes, with no subspecies.

The Green Broad-billed Thrush often moves alone or in pairs. During the spring and autumn migration seasons, it also gathers in small groups of several or more than 10 individuals. Sometimes it is also seen forming loose mixed groups with other thrushes. It is mostly active in open areas such as forest edges, wastelands, grass slopes, forest clearings and farmlands. It is a terrestrial thrush that is good at jumping and walking on the ground, and mostly moves and forages on the ground. During the breeding period, it is very good at singing, and its singing is clear and loud, which can be heard from a long distance. It often stays in one place and sings non-stop from morning to night, especially in the early morning and evening. It is active very early every day, sometimes starting to sing around 2:50 in the morning. When singing, it often stands on the branches of small trees under the trees. When it finds people, it immediately flies to the ground and moves forward by jumping rapidly on the ground.

The green broad-billed thrush mainly feeds on insects and insect larvae such as the Coleoptera family, the click beetle family, the burying beetle family, and the Lepidoptera and Diptera. In addition, it also eats other animals such as earthworms and plant fruits and seeds.

The breeding period of the green broad-billed thrush is from May to July, and the earliest one starts breeding at the end of April. The nest is shallow cup-shaped, with a relatively rough and loose structure, mainly composed of moss and grass roots. The nest is mostly placed on small trees under evergreen broad-leaved forests, 1.5-6 meters above the ground, and sometimes nests are built under coniferous forests. Each nest lays 2-4 eggs. The eggs are gray-green with red spots, and the size of the eggs is 27-33 mm × 20-23 mm. The male and female parents take turns to incubate the eggs. The chicks are late-maturing, and the male and female parents raise them together after hatching.
