Updated map of potential trichomonosis cases reported to the CWHC-RCSF from Atlantic Canada and Quebec. DISCLAIMER This map represents the approximate locations of incidents of sick and dead birds based on reports submitted to the CWHC by the public. These incidents are represented on the map as either probable (green markers) or suspect (red markers) cases as defined below. Probable Cases (GREEN MARKERS): Appropriate species based on past outbreaks (i.e. purple finch, American goldfinch, pine siskin, and Rock pigeons) and gross examination of the specimen at our Atlantic Regional Centre to identify lesions consistent with trichomonosis (these will later be identified as confirmed cases if they have appropriate microscopic lesions). These are identified as green markers on the map. Suspect Cases (RED MARKERS): Appropriate species based on past outbreaks and reported clinical signs consistent with trichomonosis (e.g. fluffed up, regurgitating food or water, unable to fly, drooling, matted wet feathers on head and breast and food debris at corners of the beak). These cases are reported by the general public to our Centre but no specimen is submitted for post mortem examination. They are identified as red markers on the map.
Trichomonosis Update: We have received reports of people distributing seed on the ground in order to feed birds in areas affected by outbreaks of Trichomonosis. Please DO NOT feed birds by placing seed on the ground (also do not use table feeders). Sick birds sitting directly on bird seed are more likely to contaminate it with Trichomonas gallinae. These feeding methods also encourage mixing of the typical species that carry the parasite (e.g. rock pigeons) and other less frequently affected birds, resulting in an increased possibility of transmission. Please consult our fact sheet for additional info and watch our facebook page and/or twitter feed @cwhcrcsf for updates to our map of potential incidents reported to us.
