觀察細節
Worn 1st cycle showing characteristics of a Cook type - structurally it has a Herring-like bill and head shape and also lacking the broad secondary skirt of the Olympics that are still around here. Although hard to trust the color of the paler brown primaries due to wear, the all dark bill in late April and general large size and pot-bellied look, would point towards GWGU influence and away from this being a pure Herring.
