A recent trip to the northern Adriatic Sea coast produced a lot of flight shots of the wintering gulls. I put together overviews of the "winter plumages" of the three most common species.
Target of my last trip to Guatemala was the endemic and very range-restricted Goldman's warbler (Setophaga coronata goldmani) in the Sierra de los Cuchumatanes highlands. This form is usually considered a subspecies of Yellow-rumped Warbler / Kronenwaldsänger but sometimes referred to as a distinct species.
