Climate Change is Threatening the Existence of the World’s Most Amazing Bird

“Moonbird is the most famous, charismatic member of a group of mid-sized shorebirds called Rufa red knots, whose numbers have plummeted so dramatically in the past several decades that they just became the first bird ever listed under the Endangered Species Act with climate change cited as a “primary threat.”


Rufa red knots are among the avian world’s most extreme long range flyers (especially in light of their relatively small size). They travel vast distances — some flying over 18,000 miles — in the course of an annual migration that begins in Tierra del Fuego, Argentina, and extends all the way up to the Canadian Arctic (and back again).


Which brings us to Moonbird’s distinction: Because he is so old — he is at least 21 — he is believed to have flown as many as 400,000 miles in his lifetime. The distance to the moon varies, depending on where it is in its orbit, but the average distance is about 237,000 miles. Thus, Moonbird has not only flown the distance it takes to reach the moon — he has also covered the bulk of the return voyage.


Assuming that Moonbird is still living — the last sighting was in May — there are reasons to wonder whether there will ever be another bird that is his equal. Why? Simply put, his subspecies has been devastated, and climate change will only make matters worse — making extreme survival of the sort that Moonbird has achieved that much more difficult.”

Wildlife Beach Restoration Groups Applaud Endangered Species Act Designation for Red Knot

Shorebird now federally protected as threatened species under Endangered Species Act

Wildlife conservation organizations leading the efforts to restore New Jersey’s Delaware Bay beaches for at-risk shorebirds today applauded the U.S. Fish and Wildlife Service decision to designate the Red Knot, a migratory shorebird, as “threatened” under the Endangered Species Act. A “threatened” designation means a species is at risk of becoming endangered throughout all or a significant portion of its range.


“This federal designation will make a big difference in strengthening the protections of this incredible shorebird,” said David Wheeler, Executive Director for Conserve Wildlife Foundation of New Jersey.


“Here in New Jersey, we are restoring the vital beach habitat that had been decimated by Hurricane Sandy, and this designation ensures the safeguards we are providing can be complemented along the East Coast,” Wheeler added.


Since the 1980’s, the Knot’s population has fallen by about 75 percent in some key areas. Wildlife biologists believe the major threat to the Red Knot is the dramatic decline of horseshoe crab eggs, an essential food source at the most critical stop over during their 8,000 mile trip from southern wintering grounds to Arctic breeding territory. High-energy horseshoe crab eggs provide nourishment for Red Knots to refuel and continue their journey.


“This is an important and needed step in the conservation and recovery of the Red Knot. It is an essential step in preventing the extinction of this amazing long distance traveler,” stated Tim Dillingham, Executive Director for American Littoral Society.


The largest concentration of Red Knots is found in May in the Delaware Bayshore of New Jersey and Delaware, where the shorebirds stop to gorge themselves on the eggs of spawning horseshoe crabs. In just a few days, the birds nearly double their weight to prepare for the final leg of their long journey.


“The major decline of horseshoe crabs in Delaware Bay is one of the largest threats to the survival of the shorebird,” explained Dr. Larry Niles, a biologist who leads the beach restoration efforts for Conserve Wildlife Foundation of New Jersey and American Littoral Society, and has studied Red Knots for three decades. “Agency groups have been working hard for the last two years, and will continue for the next two years going forward to rebuild the habitat damaged by Hurricane Sandy that the horseshoe crabs rely on. This work is integral to the recovery of the Red Knot and the shorebird’s best hope for survival.”


In the wake of Hurricane Sandy, American Littoral Society and Conserve Wildlife Foundation of New Jersey worked with the U.S. Fish and Wildlife Service, the New Jersey Division of Fish and Wildlife and the New Jersey Recovery Fund to remove 8,000 tons of debris and added 45,000 tons of sand to the beaches just before the annual spring arrival of the Red Knot in 2013.

Rare sea turtle nesting!

Saturday, December 24th, 2011

Last summer both New Jersey and Delaware had rare occurrences of sea turtles nesting or attempting to nest on their beaches.  In Stone Harbor, New Jersey this past August, a sea turtle crawled onto the beach and dug two holes in an attempt to nest in an area fenced off for beach nesting birds. Unfortunately, the sea turtle did not lay any eggs and eventually crawled back into the ocean.  Although no one witnessed the event, the turtle left strong evidence behind – its tracks! CWFNJ’s Beach Nesting Bird Program Manager along with other agency biologists was at the scene to evaluate the tracks.  Each sea turtle species has a different track pattern and leaves behind a different shape at their nesting site (their body pit).  It was determined that it was likely a state endangered loggerhead sea turtle (Caretta caretta) that attempted to nest.
