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 adapted for foraging in shallow water along shores, so their most characteristic feature is long legs that let them wade through mud and shallow water without getting bogged down, paired with slender, probing bills that reach into soft sediment to extract invertebrates. This combination supports feeding right where the prey hides, often in mudflats or along the edge of wetlands.

Long legs keep the body above the surface, helping to avoid sinking into soft mud, while the probing bill is specialized for grabbing buried prey like worms, crustaceans, and small invertebrates. Some shorebirds even have bills that are shaped differently (upturned, straight, or curved) to catch prey in particular microhabitats, but the common theme is balance between wading ability and probing feeding.

Choices describing short legs and short bills don’t support efficient foraging in mud, webbed feet are more typical of birds that swim on open water, and bright metallic plumage isn’t a typical shorebird trait, which tend to have muted colors for camouflage along the shore.
