Avian paramyxovirus type 4 (APMV‐4) has been frequently reported from wildfowl and waterfowl in recent year. However, few studies have reported on the molecular characteristics and regional transmission of APMV‐4, knowledge of which is important for understanding the genetic diversity and epidemiology of avian paramyxovirus. Herein, we report the isolation of one APMV‐4 strain, designated as QY17, from the duck in eastern China. The determined complete genome of the isolate with six gene segments 3′‐N‐P‐M‐F‐HN‐L‐5′ was 15,054 nt in length. Genetic analysis of the whole‐fusion gene of this isolate showed that QY17 was derived from a Eurasian lineage. Further phylogenetic analysis showed that the duck‐origin strain QY17 had a highly genetic relationship with representative APMV‐4 strains from wildfowl in neighbouring regions. These genetic results suggested that APMV‐4 viral exchange may occur in wildfowl and poultry via wild bird migration.
