Yes, Miss B, you'll find an unusual array of bills in Shorebirds v3, and as, Szark, mentioned each bird's bill has a specific purpose.
Just as, in gardening, sometimes we use a hoe, sometimes a shovel, other times a pick or rake-- these birds have specific bills for specific jobs. Bill morphs in the WF7 model include:
Avocet (long bill, upturned on the tip)
Curlew (long bill, downturned on the tip)
Godwit (gradual upturned bill)
Long-billed Curlew (like the curlew but an impossibly long bill (as long as the entire bird)-- used for catching prey buried deep in the sand)
Plover (short, straight bill)
Spoonbill (short, spoon-shaped bill)
Turnstone (short, upturned bill)
