Shorebirds typical feature.

• A. Long Legs and Probing Bills
• B. Short Legs and Short Bills
• C. Webbed Feet Adapted for Swimming
• D. Bright Metallic Plumage

Answer: (A)

Shorebirds are specialized for foraging in shallow water and soft substrates along beaches and mudflats. Their long legs keep the body well above the water or mud, allowing them to wade through shallow areas without sinking too deeply. The probing bills are key for finding prey buried in the substrate, such as worms and small crustaceans, by reaching into wet sand or mud and feeling for hidden food. This combination—leg length for wading and a bill designed to probe—fits how they search across flats and shoreline zones. Short legs would make wading difficult, and short bills would limit their ability to reach prey beneath the surface. Webbed feet are more typical of birds that swim a lot, like ducks, and bright metallic plumage isn’t a common camouflage or foraging aid for shorebirds, which often rely on muted tones to blend with their surroundings.
