Yes, I know that, Laurie, but it doesn't help me to answer the question. In fact that's why the question was asked in the first place. It may be as Bruce thinks, that the bill length is only advantageous in the wintering grounds.

A further question might be: I wonder if any of the bill lengths pose a restriction on the breeding grounds? I could imagine a bill as long as that of the Eastern Curlew might limit how prey can be taken, if probing is not the manner of feeding. And I have the strong impression that food is taken quite differently (from probing) on the breeding grounds.

Cheers,

Jill

The breeding grounds vary somewhat between species.  Some breed in the tundra or on mountain ridges - environments that are nothing like the habitats they winter in down here.

Regards, Laurie.

Hi All,

I was recently asked a question about waders which totally fazed me. I was asked if the length of the bill of different species of wader is of any advantage on the breeding grounds.
