觀察細節

Seen with other observers. Light coloured gull seen both at rest and in flight, appearing slightly larger than AHGU. Bill colour difficult to discern at distance, appearing dark but was also backlit. Wingtips appeared fully white. Attached is only a poor record photo (views were better to the eye). *Edited from Larus Sp. to ICGU after reviewing ID. Bill does not seem hefty enough for GLGU, nor does the birds GISS. After further look, the bird seemed closer in size to AHGU than initially thought on first views and appears long-winged.
