The documentation form by Mark Proescholdt is the only one submitted and forms the basis of this record. Other observers include Beth Proescholdt. | Elimination of similar species: A 1st winter Lesser Black-backed Gull is much smaller - about the size of a Ring-billed Gull. This is a really big gull - bigger than other possibilities. Also, much different from 1st winter Herring Gulls. | The original documentation form event lasted from 16:00:00/16:48:00. |
