观察细节
***rare; adult; clean white head, eye dark brown with little pupil contrast, faint reddish orbital ring, size close to Ring-billed, clean yellow bill with faint ghost of ring on bill. Photos of spread wing confirm ssp. ID, notably showing narrow white tips to inner primaries that were notably narrower than secondary tips. Banded with blue band on left leg reading 74J and metal band (worn? No number obvious) on right which has been reported to Eurring. Interestingly it fed both above the wave line and in the foam washed up by higher waves, as well as the wrack zone (rarely) like the American Mew, but seemed much more willing to feed in the wash zone of the waves, spending a fair amount of the time wading, swimming, or hover-pattering on the surface almost like a storm-petrel. The American Mew never did this latter behavior. Interestingly, there were additional L. c. canus observed today at Race Point (continuing bird from 12-15 April at least, seen 15 Apr by Liam Waters et al.) and Collins Lake, Schenectady Co., NY
