Article Synopsis
- Following the detection of a novel highly pathogenic avian influenza virus (HPAIV) H5N1 in Newfoundland in late 2021, Canada ramped up surveillance efforts of wild birds to track the spread of the virus nationwide.* -
- During the first year of surveillance (November 2021-November 2022), over 6,000 sick and dead birds were tested, revealing that 27.4% were positive for HPAIV across various species and regions, particularly in the Atlantic and Central Flyways.* -
- The findings highlighted the need for ongoing monitoring and collaboration, as wild birds serve as both victims and reservoirs of the virus, with a notable prevalence of Eurasian-origin strains identified throughout
Article Synopsis
- This study is the first to document a clinical case of lymphoproliferative disease virus (LPDV) in Canada, expanding its known range to Manitoba and Quebec.
- Researchers tested both live wild turkeys in Manitoba and postmortem samples in Quebec, finding a prevalence rate of 34.8% for LPDV among the sampled birds.
- Phylogenetic analysis showed that LPDV strains in these provinces are closely related to those found in Ontario and other North American samples, highlighting the importance of ongoing surveillance for this virus.
Expanding populations of North American midcontinent lesser snow geese (Anser caerulescens caerulescens) have potential to alter ecosystems throughout the Arctic and subarctic where they breed. Efforts to understand origins of harvested lesser snow geese to better inform management decisions have traditionally required mark-recapture approaches, while aerial photographic surveys have typically been used to identify breeding distributions. As a potential alternative, isotopic patterns that are metabolically fixed within newly grown flight feathers following summer molting could provide inferences regarding geographic breeding origin of individuals, without the need for prior capture.
