Today is #NationalBirdDay and 2018 is the #YearoftheBird ! Let's help continue to keep our wild birds healthy this year. You can find a few suggestions to help them out in our recent blog article: http://ow.ly/gPBf30hBqNn
The CWHC Western and Northern Region is over half way through its 2017 CWD hunter surveillance sample collection and testing program and have already identified 3 new Wild Management Zones (WMZ 3, 44, 39) in Saskatchewan with the disease and increasing prevalence of the disease in many areas. The numbers of heads submitted for testing by hunters is up 54% this year, compared to last, but is still below target numbers. This is in spite of there being no cost associated with testing, an online tagging and tracking system, and more convenient options for submitting heads for testing. This disease is having, and will continue to have, a significant impact on big game hunting and cervid management in North America. CWD is a complex disease but hunters and the public need to become informed and participate in the debate on how best to manage this disease. Fortunately there are several sources of information such as the Chronic Wasting Disease Alliance website, and the CWHC website. The CBC’s “The Current” had a recent program on the issues surrounding CWD.
Congratulations and best wishes to Pierre-Yves Daoust on his recent retirement! Pierre-Yves has been the Regional Director of CWHC-Atlantic since its inception in 1992. @upei
The Winter Holidays are for the Birds Outbreaks of trichomonosis in Eastern Canada during the summer/fall of 2017 have highlighted the necessity for strategies to prevent and control bird-feeder associated diseases and threats. These strategies include providing backyard “bird-friendly” habitat and shelter, and increasing surveillance of your back-yard birds. Fortunately, the winter holiday season provides an excellent opportunity to start actively participating in these activities, if you aren’t already.

A look back: Was the winter 2016 – 2017 challenging for barred owls in Quebec? From April 2016 to March 2017 a total of 56 barred owls (Strix varia) were submitted for post-mortem examination at the CWHC Quebec Regional Centre. This represents the highest number of submissions of this species of Strigiform to our laboratory for a given year. Most of these owls (42) were submitted during the winter (November to March). The two most common causes of death were primary inanition (23) and trauma (30). Deaths associated with inanition (starvation) are not uncommon in birds of prey, especially in young individuals with suboptimal hunting abilities. It is believed that these birds are unable to capture sufficient prey to fulfill their caloric needs and therefore progressively starve to death. These deaths are mainly observed during the fall and the winter. Retour sur l’année : L’hiver 2016 – 2017 semble avoir été difficile pour les chouettes rayées au Québec Du mois d’avril 2016 au mois de mars 2017 un total de 56 chouettes rayées (Strix varia) a été soumis pour expertise au centre régional du Québec du RCSF. Ceci représente le plus grand nombre de soumissions pour cette espèce de strigiforme au cours d’une année à notre laboratoire. La majorité de ces chouettes (42) ont été soumises durant la saison hivernale (de novembre à mars). Les deux causes de mortalité les plus fréquentes chez ces chouettes étaient l’inanition primaire (23) et les traumatismes (30). La mortalité causée par l’inanition (mort de faim) n’est pas rare chez les oiseaux de proie, surtout chez les jeunes oiseaux dont les techniques de chasse sont en développement. On suspecte que ces oiseaux n’arrivent pas à capturer suffisamment de proie et meurent de dénutrition. Cette mortalité est surtout observée durant l’automne et l’hiver.
