Observation details

I first viewed the gull from the Ballard Locks then drove 2 minutes down the street to scope it from Discovery Park, from the west side of 40th Ave West a bit south of West Cramer Street (here: 47.6673861, -122.4093796). Very dark-mantled gull darker and more slender than Olympic Gulls continuing on the smaller southern lock barrier where I had just seen it 2-3 minutes earlier. Digiscope videos taken (screenshots attached) and much better photos posted on my Ballard Locks checklist here: https://ebird.org/checklist/S282785200 My 240th species at Discovery!
