Azorean Gull ~ 3rd. W ~ Larus michahellis atlantis ~ Sao Miguel, Azores -Nov' 16

Saturday, 3 December 2016

These Azorean Gulls, Larus michahellis atlantis were all photographed on Sao Miguel, Azores last week in November.
Primary moult should be complete by the end of October, yet a few birds appear to have not yet fully grown in P10 ..
Also the P10 mirror, with some seemingly more  advanced birds lacking a mirror and some possibly more retarded birds in moult showing a mirror !!
