About These Birds
Red Knot

NT. Threatened by horseshoe crab egg depletion at Delaware Bay staging sites. Key refuelling stops critical.
Giant Snipe
Giant Snipe: 36–40 cm, the world's largest snipe with an exceptionally long bill, rich brown plumage, and heavily barred underparts. Resident in swampy grassland and marshy terrain of Venezuela, Trinidad, Colombia, Brazil, and adjacent South America. Feeds on invertebrates by deep probing. Secretive and crepuscular. Poorly known.
