Males at the spotted thimble are smaller than females: the length of the female is 9-10 cm, the male is 8-9 cm.
The upper side of the body of the female is grayish-brown with a thin transverse blackish pattern. The underside of the body is buffy, and the goiter has a rust color. The front of the chest and wings are covered with round or lunate blackish spots. The color of the males is characterized by a large number of ocher mottles on the upper side of the body, and they also have less rusty red color on the lower surface of the neck and goiter.
This species lives in South Asia: India, Nicobar and Andaman Islands, Indochina (excluding Malacca). Then, from Burma, its range extends northward to Northeast China, captures Korea and reaches the south of Primorsky Krai (to the Bolshaya Ussurka River ). The population has a pulsating character, inversely proportional to the local Far Eastern quail population, with which the species apparently competes for resources in one natural niche. In our country, it is a migratory bird, and in the south of the range - a settled one. In the Primorsky Territory, this species was observed in the fields, in river valleys, in meadows and other open areas. Inhabits dense high forbs, meadows, reeds and open swamps. Nesting described at Lake. Doriceni .
During mating games, the female takes the initiative. She runs around the male with her tail spread and feathers down. After mating, the female digs a recess in the ground, where it lays 4 eggs. The eggs are oval, white, covered with thick brownish-gray thin strokes. Their size: long axis - 25-26 mm, short - 20-21 mm. The male is engaged in incubation of the masonry, and it lasts 12 days. The chicks are covered in fluff and immediately leave the nest and follow their father. He drives them 10 days. At 10 days old, the chicks begin to fly, and at 5-6 weeks the first molt occurs. In the conditions of the south of Primorye, two masonry is done each summer (Shulpin, 1936).
They feed mainly on seeds and small insects.
