Observation details
Previously reported. Large immature gull, startlingly pale head and body but with dark brown back with much inner scalloping of the wing and back coverts. Unsure of the age of this bird but I am thinking it is 2nd winter molting into new plumage. Outer tail feathers white with black band and barring, central tail feathers fresh white. Bill bicolored pink with black ring and pink tip does not seem right for an immature LBBG of similar plumage stage. In the field, the bird seemed rather small compared to other GBBG I have seen, only slightly larger than a neighboring Herring Gull. However, bill is noticeably heavier. Perhaps a small female.
