Above, BLACK 9M0 is undergoing 4th prebasic molt. By the end of the fall, we'll call this individual a 4th cycle - essentially an adult, or adult-type if sub-adult plumage features are present. All secondaries (?) and tail feathers retained 3rd basic. The 4 inner primaries, p1-p4 are 4th generation (4th basic) while the older, mostly black, outer primaries are 3rd generation (3rd basic). Note how big the p10 mirror can be on a 3rd cycle Great Black-backed Gull.
|The p10 mirror is not so apparent at this angle.|
