He. See the red spot at the back of his head. Females lack that. Juveniles (of any gender, I believe) actually have a red cap!
Is this your pigeon? At any rate, I am definitely not an expert whatsoever, but I would also say that it's simply moulting.
Great collage! Almost didn't spot the tree creeper. Any idea which one it is, Short-Toed or Eurasian? I can never tell them apart, but considering the Short-Toed is more common (here), I usually just guess that.
Names are always confusing. In German, "Schwarzkopfmöwe" (lit. black-headed gull) is "Mediterranean gull" in English. Your "Black-Headed Gull" is "Lachmöwe" in German (lit. laughing gull) and your "Laughing Gull" is an "Aztekenmöwe" in German. Not sure why it has to be so confusing!
Anyway, great photo! :>
Not sure why the only way to have someone appoint you as a mod is to post a comment in the community you want to become a mod of lol But hello!
That's a bird loaf if I've ever seen one. Cute pigeon! I guess that answers my question from earlier under another post :>
