Slaty-backed Gull - Windsor Landfill, CT. Nov 28th. Thought to be fourth-cycle. Potentially the first state record.
This fourth cycle Slaty-backed Gull at Windsor in Connecticut inspired much discussion on the ID-Frontiers listserve, especially concerning the bird's back color. By coincidence, the Ujiharas have just posted more fabulous shots of Slaty-backed Gulls on their wonderful Japanese Gull-site. They include this amazing image set of the same bird taken within a two minute period and have not made any adjustments to the images regarding brightness or contrast - the images are rather revealing. Enjoy!
