The Glossy Ibis, also known as the Glossy Ibis in English, is a dark chestnut ibis with a shimmering color. It looks like a large dark curlew and has no subspecies.
When flying, the painted ibis stretches its head and neck forward, and its feet extend behind its tail feathers. It mainly relies on the flapping of its wings, but it also glides during the flight. When flying, it flies in dense small groups or in a long "V" formation. It flaps its wings quickly, has good gliding skills, is good at flying, and usually flies a long distance. Sometimes it flies very high, and then falls sharply headfirst.
The painted ibis mainly feeds on small invertebrates such as aquatic insects, insect larvae, shrimps, crustaceans, and mollusks. Sometimes it also eats small vertebrates such as frogs, tadpoles, small fish, spiders, and small snakes. It usually forages alone or in small groups. When foraging, it walks slowly along the water's edge while inserting its long, curved beak into the mud or shallow water to explore for food, or preying on surface food it sees. Sometimes it even completely immerses its entire head in the water to explore for food at the bottom of the water. Sometimes it also runs to chase food. It forages during the day and returns to its habitat, trees, to roost at night.
The call of the painted ibis: a nasal grunt, bleating and cooing in the nesting area.
The breeding season of the ibis varies depending on the region. It usually nests in groups in spring, and often nests with other herons and storks. The size of the group ranges from a few, dozens to hundreds. It usually nests on dry land or bushes in dense reeds, and often nests on low trees. The nest is mainly composed of dead branches or dry reed stems and leaves, and a few grass stems and leaves are placed in the nest.
The size of the nest is 30-40 cm in diameter and 4-27 cm high. The nest is jointly undertaken by male and female birds. Usually the male bird transports the nesting materials, and the female bird stays on the nest to build and guard the nest to prevent other birds from stealing the nesting materials. Each nest lays 3-5 eggs, usually 4, and occasionally as few as 2 and as many as 6. The eggs are oval in shape, blue in color, 53 mm × 36 mm in size on average, and weigh 31-39 grams. The time of nesting and egg-laying in the same group is not synchronized. The breeding period can last for more than 5 weeks or even longer, and re-nesting is often found.
Usually, the first egg is laid and incubated, which is shared by the male and female birds. The male bird mainly incubates the eggs during the day, and the female bird incubates the eggs at night. The incubation period is 21 days. The chicks are late-maturing and are fed by the parents after hatching. The parents usually spit out the food after returning to the nest, or the chicks put their mouths into the parent's throat pouch to peck at it, and sometimes even put their entire heads into the parent's throat pouch. The chicks can leave the nest and fly at about 25-28 days old.
The number of painted storks in China is not large, and the distribution area is very narrow. Due to the continuous disappearance of swamps and the shrinking area of rivers and lakes, the habitats on which they depend for survival, their numbers are decreasing. At the same time, the increasingly serious environmental pollution has caused an increase in harmful substances in the water, making their living environment worse and worse. Finally, people suddenly found that they could no longer find the beautiful figure of the painted storks. The Chinese Red List of Endangered Animals had to declare that the painted storks were extinct in China. Since 2009, there have been traces of them in China. In May 2022, the rare bird painted storks were discovered in Kunming, Yunnan.
