Two crested ibis chicks hatched on April 22 at a rewilding base in the Yellow River Delta National Nature Reserve in Dongying, marking the first successful artificial incubation of the year. Both chicks are in good health and are receiving professional care.
The crested ibis, a globally endangered species under top-level national protection, has adapted steadily since its introduction to the reserve in 2022. This breeding season, four adult pairs produced 20 fertilized eggs, and incubation is progressing smoothly.
Interestingly, several subadult pairs have also shown breeding behavior, with one pair successfully laying eggs. This challenges the typical understanding that the species reaches sexual maturity at around two years of age. Researchers believe that the abundant food resources, suitable habitats, and relatively low environmental pressures in the delta might be why.
Meanwhile, reintroduced birds have begun forming stable wild breeding populations, with nests observed in the natural wetland environment this spring.
These outcomes highlight the ongoing ecological restoration efforts in Dongying. Through integrated conservation measures, including wetland rehabilitation, water system improvement, and invasive species control, the region has significantly enhanced habitat quality.
By 2025, the number of bird species in the reserve had increased substantially, underscoring its growing importance as a natural habitat for rare and migratory birds.
