“…The interface between wild birds and domestic poultry is studied in particular (Wiethoelter et al., 2015 ) as wild birds frequently are suspected to be involved in the occurrence of outbreaks of different diseases in captive‐bred birds. While many studies are insufficiently conclusive to confirm or characterize the roles of wild birds in such outbreaks (Caron et al., 2017; Gaidet & Caron, 2016 ), limiting contact between wild and captive‐bred birds is usually advocated in poultry breeding biosecurity guidelines as precautionary measures to prevent sanitary and economic consequences of epizootic events.…”

Worldwide, wild birds are frequently suspected to be involved in the occurrence of outbreaks of different diseases in captive-bred birds although proofs are lacking and most of the dedicated studies are insufficiently conclusive to confirm or characterize the roles of wild birds in such outbreaks. The aim of this study was to assess and compare, for the most abundant peridomestic wild birds, the different exposure routes for avian influenza and Newcastle disease viruses in conservation breeding sites of Houbara bustards in the United Arab Emirates.To do so, we considered all of the potential pathways by which captive bustards could be exposed to avian influenza and Newcastle disease viruses by wild birds, and ran a comparative study of the likelihood of exposure via each of the pathways considered.We merged data from an ecological study dedicated to local wild bird communities with an analysis of the contacts between wild birds and captive bustards and with a prevalence survey of avian influenza and Newcastle disease viruses in wild bird populations.We also extracted data from an extensive review of the scientific literature and by the elicitation of expert opinion.Overall, this analysis highlighted those captive bustards had a high risk of being exposed to pathogens by wild birds. This risk was higher for Newcastle disease virus than avian influenza virus, and House sparrows represented the riskiest species for the transmission of both viruses through direct exposure from direct contact with an infectious bird that got inside the aviary and indirect exposure from consumption of water contaminated from the faeces of an infected bird that got inside the aviary for Newcastle disease virus and avian influenza virus, respectively. These results also reaffirm the need to implement biosecurity measures to limit contacts between wild and captive birds and highlight priority targets for a thoughtful and efficient sanitary management strategy.
