You can see it has a beak deformity with elongation and downcurving of the upper mandible. It's bit unsightly but is unlikely to interfere with feeding and preening.
I hadn't realised what enormously long rear toes skylarks have. Of course they are normally seen in the air or standing in grass when you can't see their toes.
Because of its strange upper mandible and the way it ran around the beach (and its crest and colouration) it reminded me a bit of a roadrunner!
