On Saturday, December 9, Peter Gadd in Miramichi, New Brunswick, photographed an apparent Mistle Thrush feeding on Mountain Ash berries in their yard. This is not only a 1st record for New Brunswick and Canada, but it is a potential 1st ABA Area record of this wide-ranging Eurasian Turdus thrush.
Miramichi is on the central coast of New Brunswick. The closest cities are Quebec City, Quebec, and Portland, Maine. It is about 6.5 hours by car from either. EDIT: Note that some commenters have suggested Moncton, 90km south of Miramichi, and Halifax, Nova Scotia, as places to start as well. The homeowners, Peter and Deana Gadd, are birder-friendly. Their address can be found on this post on the New Brunswick listserv. Like many vagrant thrushes, it is likely that this bird is moving around with local flocks of frugiverous birds and could be anywhere in the vicinity. Please respect private property.
Mistle Thrush is the largest species of thrush in Eurasia, a bit larger, even, than our familiar American Robin. The species consists of three subspecies, of which the nominate subspecies, which breeds in northern Europe, is the most likely to appear in North America.
