The risk of avian influenza outbreaks in poultry is partially dependent on the probability of contact between domestic poultry and wild birds shedding avian influenza (AI) virus. The major objective of this study was to document wild bird activity on poultry farms to determine which wild bird species should be targeted for AI surveillance in Canada. We collected data in 2 major poultry producing regions of Canada, southwestern Ontario and the Fraser Valley of British Columbia, on the relative abundance of various wild bird species found on poultry farms and on how these species utilized habitat around poultry farms. We reviewed the published literature to determine what was known about AI pathobiology in the species we observed. From these results we created a list of 10 wild bird species that are a priority for further study. These species are the European starling, barn swallow, rock dove, American crow, northwestern crow, American robin, dark-eyed junco, song sparrow, horned lark, and common grackle. Abundance of these and other species varied between provinces and seasons.
家禽中禽流感爆发的风险部分取决于家鸡与携带禽流感(AI)病毒的野生鸟类之间接触的可能性。本研究的主要目的是记录家禽农场中野生鸟类的活动情况,以确定在加拿大应对哪些野生鸟类物种进行禽流感监测。我们在加拿大两个主要家禽生产地区,安大略省西南部和不列颠哥伦比亚省的弗雷泽河谷,收集了有关家禽农场中发现的各种野生鸟类物种的相对丰度,以及这些物种如何利用家禽农场周围栖息地的数据。我们查阅了已发表的文献,以确定我们所观察物种的禽流感病理生物学情况。根据这些结果,我们列出了10种野生鸟类物种清单,它们是进一步研究的重点对象。这些物种是欧洲椋鸟、家燕、原鸽、美洲鸦、西北鸦、美洲知更鸟、暗眼灯草鹀、歌带鹀、角百灵和普通拟八哥。这些物种及其他物种的数量在不同省份和季节有所不同。
