Blackbird with a Crossed Bill

From time to time a bird is seen with a bill which has become distorted in growth. One such is this blackbird which has been visiting the garden for months. I would imagine it would be very difficult, if not impossible, for it to hunt for worms in the ground but it has learned to put its head on one side so it can pick up any seeds which drop from the feeders. So far it seems to have thrived well.

One species whose numbers have declined rapidly in this area is the Greenfinch so it was a real pleasure to spot this one waiting to find a vacant perch on the seed feeder,

  1. It's probably just me but it always seems to be blackbirds that suffer mutation. Albino ones are not common but i must see one a year.

  2. Unusual bill on that Blackbird John. Amazing how they manage to survive like that at times.

  3. Lovely photos of both birds John! I have read that in America in particular beak deformity is a growing concern and is becoming more so here too. I remember reading that the BTO are running a Big Garden Beak Watch so have looked it up and you might be interested to read about it here:

  5. You may be interested in this article John, It's an American study, but quite interesting. Your blackbird will survive, its bill isn't too deformed and as you say it is learning to feed sideways on... put some mealworms out too that'll help.

  6. I've never seen a bird with a deformed beak like that; I'm glad it is able to adapt. The Greenfinch is a great photo too. Birds seem to have such expressions on their faces...

  9. Hello Jan. I tried the BTO site but it was such a hassle trying to sign in I gave up.

  12. Hello Glo. I see about one a year, usually Blackbirds. I love the expressions on the smaller birds' faces.
