The Collared Dove (Streptopelia decaocto) has two subspecies.

The grey turtle dove is a social species, mostly living in small groups or mixing with other turtle doves. In places where food is plentiful, such as cereals, sizable communities can form. The call of the turtle dove is "coo-goo", the second sound is stronger and repeated many times. Occasionally, it emits a loud, piercing, hollow call for about two seconds, especially during summer landings.

The turtle dove feeds mainly on the fruits and seeds of various plants. They also eat grass, grain, and insects.

Adult grey dove nests in trees and lays white eggs in nests woven with branches. Incubation takes 14-18 days, and the chicks will fledge after 15-19 days. The birds are unwary of humans and can often be found around human settlements. Breeding season from April to August. Breed 2 litters a year. They usually nest in small trees or shrubs. Each brood lays 2 eggs, which are milky white in color and oval in shape. The long diameter of the egg is 2.9-3.4 cm and the short diameter is 2.3-2.6 cm. The eggs are incubated mainly by the female. Male birds mostly rest and guard near the nest. Incubation period is 15-17 days. After hatching, the chicks are fed by both sexes, and after 15-17 days of feeding, the chicks can fly away from the nest.

In October 2020, the State Forestry and Grass Administration issued the Notice on Regulating the Scope of Classified Management of Fasting Wild Animals, prohibiting the breeding activities for the purpose of consumption, and guiding farmers to stop breeding except for special circumstances such as proper preservation of seed sources.

Listed on the International Union for Conservation of Nature (IUCN) 2016 Red List of Threatened Species ver 3.1 - Not Threatened (LC).
