Join us on a live tour of the Caofeidian Wetland, home to over 1,200 species of wildlife, including 238 species of wild plants from 63 families and 307 species of birds from 17 orders and 52 families in Tangshan City, north China's Hebei Province. One of the common birds found there are egrets, which breed from March to July each year and have an incubation period of about 25 days. The female stays in the nest while both parents share the incubation and feeding duties.
