I’ve included two photos of in-flight juvenile Whimbrel that I took in the first week of August 2016. I’m sharing these images for the simple reason of illustrating how a young juvenile differs from an adult. The age of these birds is told by the overall fresh, clean plumage and relatively short bill. It’s that simple in August. In a few months the bills will grow to a length comparable to the adults and determining age will become more difficult.
