In short

The Long-billed Dowitcher and the Bar-tailed Godwit are two shorebirds that differ significantly in size, plumage, behavior, and habitat preferences. The Long-billed Dowitcher is characterized by its long, straight bill and distinctive feeding motion, while the Bar-tailed Godwit is larger, with a longer neck and a more pronounced bar on its tail. These distinctions can help birdwatchers accurately identify each species in the field.

Identification tips

  1. Birds of the World Similar-Species Diagnostics:
  2. "Although similar to the Short-billed Dowitcher in appearance, the Long-billed differs from that species ecologically." (Source: Birds of the World)

  3. The Bar-tailed Godwit, in contrast, is noted for its "barred tail," which is visible in flight, as well as its larger size and more social behavior during migration.

  4. AI Field Diagnostics:

  5. Size & Shape: Look for the overall larger size and longer neck of the Bar-tailed Godwit, which gives it a more elongated silhouette compared to the more compact Long-billed Dowitcher.
  6. Bill Shape: The Long-billed Dowitcher has a straight, long bill, while the Bar-tailed Godwit’s bill is longer but slightly curved.
  7. Feeding Behavior: Observe the Dowitcher's "sewing machine" feeding motion, which is unique and distinct from the more general pecking behavior of the Godwit.
  8. Habitat Preference: Pay attention to habitat; if you see a bird in freshwater wetlands, it’s likely a Long-billed Dowitcher, whereas the Bar-tailed Godwit is more often found in coastal mudflats.
  9. Plumage Features: Note the Long-billed Dowitcher’s rufous-brown plumage with streaking, and the Bar-tailed Godwit’s more uniform coloration and distinct barred tail in flight.
  10. Social Behavior: If you spot large flocks, they are likely Bar-tailed Godwits, while the Long-billed Dowitcher often remains solitary or in smaller groups.

By focusing on these key differences in size, plumage, behavior, habitat, and vocalization, birdwatchers can effectively distinguish between the Long-billed Dowitcher and the Bar-tailed Godwit in the field.

  • Long-billed Dowitcher: Medium-sized sandpiper, measuring approximately 10-11 inches (25-28 cm) in length, with a wingspan of about 20 inches (51 cm). It has a chunky body and relatively short legs compared to the Bar-tailed Godwit.
  • Bar-tailed Godwit: Larger than the Long-billed Dowitcher, reaching lengths of 14-16 inches (36-41 cm) and a wingspan of about 30 inches (76 cm). This species has a longer neck and legs, which gives it a more elongated appearance.
  • Long-billed Dowitcher: During the breeding season, it has a rich rufous-brown coloration with darker streaks on the head and back, and a paler underbelly. Notably, its long bill, extending twice the length of its head, is straight and thin.
  • Bar-tailed Godwit: Exhibits a more uniform coloration, with a warm brown back and a paler underbelly. Its most distinctive feature is the barred tail, which is visible during flight. The bill is also long, but slightly more curved than that of the Long-billed Dowitcher.
  • Long-billed Dowitcher: Known for its characteristic "sewing machine" feeding motion, the Long-billed Dowitcher probes into mud and silt to find food. It often forages in freshwater wetlands and is more solitary or in small groups.
  • Bar-tailed Godwit: Feeds by pecking at the surface or probing the mud, often seen in large flocks. This species has a more social behavior, especially during migration when it gathers in large numbers.
  • Long-billed Dowitcher: Prefers freshwater wetlands, small pools, and salt-marsh vegetation, often found in areas with abundant mudflats. Breeds primarily in coastal western and northern Alaska to eastern Siberia.
  • Bar-tailed Godwit: Commonly found in intertidal zones of coastal habitats, including mudflats and beaches. It has a broader migratory range, breeding in subarctic and arctic tundra of Alaska and migrating to temperate and tropical coasts.
  • Long-billed Dowitcher: Produces a distinctive call while flying and feeding, which can be described as a "pee-witch-er" sound, especially during its breeding display.
  • Bar-tailed Godwit: Generally more silent but can emit soft calls, particularly during the breeding season.
