Canada / Cackling Goose Review, November 2009.
The IRBC is commencing a review of all accepted "small" Canada Goose records while at the same time assessing all recent Cacking Goose claims.
Given the complexity of Cacking and Canada Goose taxonomy and the ongoing search for definitive identification criteria we will need robust submissions, ideally consisting of photographs AND detailed field observations in order to substantiate all records both new and old. Photos alone may not be enough - we will require field observations to back up impressions of a bird's size, shape and plumage colour and pattern. Similarly, field descriptions lacking sufficient detail, and not backed up by good photos or field sketches will be hard to substantiate. If you can provide any photos or detailed field notes to help with this review we would love to hear from you.
Please note: This review has now concluded and you can read the findings HERE.
