Long time since last post now. Now finally the focus goes back to gulls (and all the other birds that might show up!). Starts of with a Black-headed Gull.
Black-headed Gull, 2cy (1. summer), (Frognerkilen, Oslo) In flight we can see some old feathers in coverts, and all old secondaries (outhermost is gone on both wings). The bird moults P8. |
At end a 3cy Lesser Black-backed Gull.
