Great Black-backed Gull (1st cycle). |
Great Black-backed Gull (1st cycle). A rather dark bird holding on well to its juvenile neck, breast and flank feathers. |
Two 1st cycle GBBGs and a 2nd cycle GBBG (back right). Did you notice the Glaucous Gull back there? |
Glaucous Gull (2nd cycle). |
Glaucous Gull (1st cycle). Outer primaries worn and bleached (see below). |
Inner primaries show brown markings that are consistent with the rest of the plumage. The Outer primaries appear bleached and more worn. |
The 2nd cycle Glaucous on the right would not stop bullying everything around it - except for one large, presumably male, GBBG. |
This 2nd cycle type is sporting a few adult-like rectrices. My guess is somewhere along the line, a few feathers were ripped out and then readily replaced. Tail and flight feathers are commonly tugged at during fights with congeners.
Herring Gull (2nd cycle type). |
Herring Gull (2nd cycle). |
If the inner primaries were any darker, you might start to suspect a LBBG. |
Adult type Herring Gull. Shows little white mirror on p9 and small black spot on outer edge of p4. I imagine this wingtip pattern is age-related and likely represents a young adult. |
Herring Gull (3rd cycle type). |
Herring Gull (2nd cycle type). The contrasty upperparts make for a really neat-looking seabird... |
