Each bird was observed, individually counted, and photographed for the documentation During today’s birdwatching, we observed approximately 35* River Terns in the area. Among them, a group of five individuals was perched together, within which one bird appeared noticeably different, showing a slightly greyish coloration compared to the others. The cause of this variation is unclear, and we would welcome insights from bird experts on whether this difference could be attributed to breeding plumage or another factor.
