- Slaty-backed Gull (adult). Manitowoc, Wisconsin. 04 April 2015.
- This individual was seen on and off for over a month but could not be identified to species until 04 April when the original finder observed it closer to shore.
- Western Gull (1st cycle). Sierra County, New Mexico. 09 April 2015.
- Mew Gull (adult). Southport, Connecticut. 10 April 2015.
- Another presumed Kamchatka Gull (the 4th one on the Atlantic Coast in 6 months). North America's default East Coast subspecies has always been nominate canus. The recent rash of L.c. kamtschatschensis is curious, to say the least. Perhaps it's a good time to reassess historic records where photos and/or specimens are available.
