Abstract: From February to August in 2017, the breeding ecology of the common moorhen（Gallinula chloropus） was studied in Chenqiao village in Xinxiang Yellow River Wetland reserve and compared with other five areas. The results showed that the breeding season of common moorhen is from early March to the end of May,and the newly hatched birds can be seen at April 1. The nests were built in lotus pond with sparse reeds,nesting with withered reeds. The average outside diameter of the nests was （26.80±1.21） cm,inside diameter was （15.28±1.21） cm,the deep was （6.48±1.02） cm,and height was （14.50±2.79） cm. There were （8.5±2.1） eggs in each nest on average. The average long diameter of the eggs was （4.18±0.17） cm,short diameter was （3.06±0.16） cm,the weight of eggs was （19.71±0.21） g. The hatching period of common moorhen was 16 to 18 days, and the hatching rate was 95.2%. The reproduction period of common moorhen in Chenqiao village in Xinxiang was the earliest compared with other five areas. The common moorhen turns out to be a resident bird in the reserve,may be due to climate change and food enrichment.
