2. Habitat in the open forest area at an altitude of 1200- 1400 meters, wading in nearby streams, swamps and rice fields, strolling in aquatic animals such as Yu Xiaoyu, crabs, frogs and snails, and eating insects at the same time; Rest overnight in a tall tree;
Stay in birds and wander to the low mountain plain in groups in autumn and winter; Nesting begins in April and May, and one nest is bred every year, with 2-4 eggs per nest. Parents hatch and hatch. The incubation period is about 30 days, and it leaves the nest after 40 days. Sexual maturity is 3 years old, and the longest record is 37 years.
3. Habitat:
Crested ibis lives in temperate mountain forests and hilly areas, and most of them are adjacent to wetland environments such as paddy fields, floodplains, ponds, streams and swamps. Crested ibis likes wetlands, swamps and rice fields very much in the wild. I like to inhabit tall trees in sparse forest areas at an altitude of 1200 ~ 1400 meters.
Once widely distributed in eastern China, Japanese, Russian, North Korea and other places, the population declined sharply due to environmental deterioration and other factors.
Extended data:
Life habits of crested ibis;
1, habit
Sex is secluded and quiet, except when you take off, you don't sing during general activities. Often alone or in pairs or groups, rarely live in groups with other birds. Slow movement, slow wings to fly. The head and neck are straight forward, and the claws extend backward, but they do not protrude beyond the tail. They live in tall trees at night. ?
2. Eating habits
It mainly feeds on invertebrates and small vertebrates, such as small fish, loach, frog, crab, shrimp, snail, cricket, earthworm, beetle, Hemiptera, crustacean, other insects and insect larvae. The foraging activity is during the day.
Usually foraging in shallow water or rice fields near the water, but also foraging in mud and ground. When looking for food on the ground, I often walk slowly and lightly. I searched the land in front of me with my eyes. When I found the food, I immediately pecked it with my mouth. When foraging in shallow water or mud, we mainly rely on inserting long and curved mouths into soil and water to find food.
3. Immigration
In autumn, most of the original breeding populations in eastern Russia, Korea, northern Japan and northern China will migrate to southern Japan and south of the Yellow River in China to the lower reaches of the Yangtze River, Fujian, Taiwan Province Province and Hainan Island, and some will stay in Korea for the winter. However, populations that breed in China and southern Japan usually do not migrate, but are resident birds.
The population distributed in Yangxian County, Shaanxi Province, China did not migrate, but wandered around after the breeding season. In July, a young bird that left the nest was found 20 kilometers away from the nest.
