|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.
|This image is unquestionably underexposed (to help capture the GLGUs). The snow also does a good job of tricking the camera's metering system which in turn makes the Herring Gull look extra dark - no it's not a Vega Gull :).|
|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...|
