Figs 9 and 10) These are early juveniles with all-black bills. They can be confusing, recalling Lesser Black-backed Gull. They show up on West Coast beaches in late July through early September. By then, their bills should be turning pale at the base. Fig 4 is Quiz Gull #1. A full discussion can be seen here. Photos courtesy of Don DesJardin. |
