*rare; juvenile by itself, which is especially unusual—all or almost all Cacklings I have seen in the state, and in the East, have been adults (most vagrant geese are adults—especially true for Barnacle and Pink-footed, less so for Greenland White-fronts and Ross’s). [note: I checked my records, and of 19 sightings of 13 records involving 20 individuals, all have been adults prior to this one, including a group of 8]. Age by smooth, unbarred, flanks, ragged neck sock border, and neat, pale edging above. Identification to species by size (60% of Canadas in direct comparison), short neck, blocky head, comparatively short and triangular Bill. However, this bird was a bit longer necked, rounder headed and longer billed than many, and also not strikingly pale in the field (more of an adult trait in hutchinsii). This leaves me unwilling to eliminate taverneri here, which tends toward the larger and lankier end of the Cackling spectrum (but I expect this is just a large hutchinsii). I don’t think a hybrid Cackling x Canada is involved here, but those should be watched for if they can be identified.
