Sketch of 1st-year bird made from memory a few hours later.
觀察細節
Seen circling just offshore from south Wilson Cove. The 3 1st-year birds were closer to shore (100m out) and seen quite well. They had a distinctive black band near the tip of the tail, triangular blackish wing tips with indistinct separation from light gray wing coverts. Some mottled brown [in greater wing covers?] giving wing a contrast of whitish secondaries set off against darker coverts and blackish primaries (see sketch). Mantle light gray, perhaps with indistinct brown mottling. Bill dark at tip, pale at base. The 2 adults were farther offshore and were identified by pale gray mantle, small size, and obvious association with the 3 1st-year birds.
