Figure 1. Seroprevalence for nucleoprotein antibodies in red-necked stints and Pacific black ducks, Australia, 2011–2018. A) For red-necked stint, year represents the austral summer period, October–April, when this species has a migratory nonbreeding stopover in Australia. B) For Pacific black duck, year represents calendar year. (No samples were collected in 2015.) Inset maps show the number of samples collected from each species in each state over the course of this study. Error bars represent seroprevalence 95% CIs for each state across all years; color dots represent estimates of seroprevalence at each sampling occasion. NSW, New South Wales; NT, Northern Territory; QLD, Queensland; SA, South Australia; TAS, Tasmania; VIC, Victoria; WA, Western Australia.
