In order to improve current understanding of the molecular epidemiology of avian avulavirus 1 (AAvV-1, formerly avian paramyxovirus 1) in wild birds in Kazakhstan, 860 cloacal swab samples were evaluated. Samples were collected from 37 families of wild birds in nine different regions in the years 2011 and 2014. Overall, 54 positive samples (4.2%) were detected from 17 different families of wild birds, and 16 AAvV-1 isolates were characterized. Three of the isolates contained the fusion protein cleavage site motif RRQKR, and 13 contained KRQKR, which is typical for pathogenic strains of AAvV-1. The AAvV-1 isolates were found to belong to the genotypes VIg and VIIb.
