観察結果の詳細

Minimum count of more typical individuals showing intermediate characteristics, with dozens additionally seen that were possible but variably ambiguous. Majority 1st cycle but mixed ages with many adults. In general counting individuals with more Herring-like structure outside the normal size range of Thayer's and typically bill size/shape fitting Herring. Adults with Herring-like mantle/primary contrast but showing primary tips grayer than expected and/or with atypically large white mirrors/tongues, irises often mid-dark occasionally clear like Herring but with pink orbital as in G-w, bill color flat or lacking greenish overtones seen in adult Thayer's. 1st cycles typically with Herring-like juvenile patterning (often somewhat smeared in the coverts), but distinctly paler brownish primaries often with Thayer's-like pale fringing or pale inner webs. Bills often paling or pink at the base unlike most 1st cycle Olympic.
