Will post videos I took. Seen mixed in with the Ring-billed Gulls. Stayed here until 8:15 PM when it departed with the other gulls to fly off to roost somewhere else for the night. I feel this bird was probably juvenile molting into its first winter plumage. The mantle was dark like usual, but it was scaly looking and not the solid dark color as an adult would be. I'll admit I'm no gull expert, so I could be wrong on this.
