Porzana paykullii

Band-bellied Crake, whose foreign name is Band-bellied Crake, is a small wading bird with no subspecies.

Spotted frogs migrate to Northeast China to breed in mid-to-late April in spring, and migrate away from their breeding grounds in late September and early October in autumn.

Spotted frogs often live alone or in small groups. Nocturnal. Mainly active at night and dawn and dusk. During the day they mostly hide in bushes and grass. He is good at walking and can run very fast on the ground, even under dense grass. Generally, they rarely fly. Even if they are frightened in times of crisis, they will not fly very far and fall into the grass or bushes. When flying, the legs hang downward. Very vocal, especially at night. Often a short sound like "urrrr" is made.

Spotted frogs feed on knocking insects, caterpillars, lepidopteran and coleopteran insects and larvae. Also eats snails, mollusks and other small invertebrates and plant fruits and seeds.

The breeding period of spotted frogs is from May to July. Single formulation. Male and female nest in pairs. The nest is usually built in a depression in the ground, in the shape of a shallow plate, placed in a dry place on higher ground, hidden among grass or shrubs, and is generally relatively hidden. The nest is mainly lined with twigs and grass stems, with an outer diameter of 12-14 cm, an inner diameter of 9-12 cm, a nest height of 8-13 cm, and a nest depth of 4-5 cm. Males and females build nests together. Each clutch lays 6-9 eggs, occasionally as many as 10 and as few as 4. The eggs are nearly oval, light earthy brown, with white spots, especially dense at the blunt end. The size of the eggs is 33-36 mm x 26-27 mm. After all the eggs are laid, incubation begins. The male and female parent birds take turns incubating the eggs. The incubation period is 20-21 days.

Since the 1960s, habitats have been destroyed, and swamp wetlands suitable for nesting of this species have been reclaimed as farmland. Tropical rainforests and monsoon forests in the low mountain areas near the Tianba area have been cut down, and economic trees and crops such as rubber have been planted, threatening the species. Frogs lost their habitat. In addition, indiscriminate hunting has caused the number of spotted frogs to decline and is on the verge of extinction.
