What advantage does the Whimbrel's specialized bill give it compared to shorter-billed shorebirds?

Answer

It allows access to the sub-surface layer of prey items.

The specialized adaptation of the long bill carves out a niche by allowing the bird to target deeper worms or shellfish, rather than competing for very surface-level food items.
