This is the second gull I’ve been lucky enough to capture.
After some research and a call out for help we discovered that the banding was done by Dr Julie Ellis
You can check out her blog here which details some of the gull sightings and why they band them.

Banding and Tagging
Initial trapping was conducted throughout January, February, and March 2008, utilizing three methods: a walk-in nest trap, Steele’s net, and rocket net. All methods successfully captured the targeted species, although the rocket net and Steele’s net were much more effective and efficient. Starting in the fall of 2008, a net launcher and net gun were exclusively utilized for trapping.
Following capture, all birds are fitted with an aluminum federal leg band. A uniquely numbered colored leg band is placed on the opposite leg of all birds [Picture 1]. Finally, on most birds, a colored, uniquely numbered wing-tag is attached to each wing. These wing-tags make long-distance identification possible, particularly when it is difficult to see or read the leg bands [Pictures 2-4]. Wing-tags are color-coded based on the capture site’s proximity to either Wachusett or Quabbin Reservoir [Picture 5].
