Shorebird Identification: A Guide to Beach Birds, Sandpipers, and Waders

Shorebirds are the birds of beaches, mudflats, and estuaries — ecosystems that support some of the most spectacular migrations on Earth. From the tiny Semipalmated Sandpiper to the majestic American Avocet, shorebirds demonstrate the incredible diversity of avian life along our coasts.

Major Shorebird Groups

Semipalmated Sandpiper

Calidris pusilla

Size: 5–6 inches

Weight: 0.5–0.9 oz

Lifespan: 7–8 years

Diet: Small crustaceans, mollusks, insects

The Semipalmated Sandpiper is one of the most common shorebirds along the Atlantic coast. During migration, millions pass through coastal stopover sites, gaining critical fat reserves before crossing the Gulf of Mexico.

Fun Fact: Semipalmated Sandpipers migrate along the Atlantic Flyway, stopping at Delaware Bay to feed on horseshoe crab eggs — a critical energy boost for their 2,500-mile non-stop flight to South America.

Migration Magnitude

Some shorebird species migrate up to 9,000 miles annually — the longest non-stop flight of any bird. The Bar-tailed Godwit flies 7,000 miles from Alaska to New Zealand without stopping. Understanding migration is essential for timing your shorebird watching.

Feeding Techniques

Probe-feeders insert bills deep into mud. Stalkers walk slowly pursuing prey. Skimmers fly low with bills open through water. Sifting birds dip bills into shallow water and filter food. Each technique corresponds to specific body shapes and bill forms.
