INTERESTING FACTS

  • The Red Knot was first described by Linnaeus in his Systema naturae in 1758 as Tringa canutus.
  • It does not regurgitate undigested hard parts of prey, as do many species of birds. Instead it excretes the hard parts in the feces.
  • It is estimated that during migration, as much as 90% of the total population of this bird can be found in Delaware Bay, feeing on the eggs of spawning horseshoe crabs.
  • A group of knots are collectively known as a "cluster", "fling", and "tangle" of knots.
