| Occurrence Remarks |
The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. Other observers include Tom Kent and Dick Tetrault. | Elimination of similar species: 1st winter Herring Gull has a very dark secondary bar, often has lighter head, and generally has a much more 'contrastry' appearance involving darker and lighter shades of brown. Overall, the 1st winter Herring is darker brown. | The original documentation form event occurred in the afternoon. |
