Migration never ceases to amaze me.... This is from the June Birding Community E-bulletin
At least one individual Red Knot has traveled from the tip of South America to the top of Canada after passing through the famous stopover site of the Delaware Bay for 21 years. This knot is nicknamed "Moonbird," because the bird has already flown the equivalent distance between the Earth and the moon and more than halfway back during its epic migrations. The bird has been making the trip for over two decades and this spring was observed on 25 May at Reeds Beech, New Jersey, with its identifiable orange-colored leg-band and the number "B-95" on it.
Red Knots feasting on horseshoe crab eggs in Delaware Bay have dropped in numbers from over 100,000 to perhaps under 25,000 in about a dozen years. Not surprisingly the U.S. Fish and Wildlife Service recently announced an extension (to 15 June 2014) for public comment concerning a proposed Threatened listing of the rufa subspecies of the Red Knot under the Endangered Species Act (ESA).
