More Gulls

Is this a 2nd winter aka 3cy Black-headed Gull? Didn't get a flight shot unfortunately!

  1. Hi Tim
    I would think this is just an advanced first winter. There is still a bit of brown in the tertials and the bill pattern is standard 2cy..
    I think true 3cy are hard to do unless you get a photo of the black leading edges to the primaries - I always overlook them as adults!
