Red Knots Endangered, just knot officially

by Lanny McDowell on December 19, 2008

 Here is an excerpt from the American Bird Conservancy’s report about the current status of Endangered Species Listing by the U.S. Fish and Wildlife Service, thanks to Betty Andersen:

Government Review Confirms Red Knot and Other Imperiled Bird Candidates Should Be Listed as Endangered Species

 
 

The U.S. Fish and Wildlife Service (FWS) has released its revised list of species that are candidates for listing under the Endangered Species Act (ESA). Designation as a candidate species is not a requirement for listing under the ESA, and FWS can, and regularly does, list animals and plants without first placing them on the Candidate List. As a result, The U.S. Fish and Wildlife Service (FWS) has released its revised list of species that are candidates for listing under the Endangered Species Act (ESA). Designation as a candidate species is not a requirement for listing under the ESA, and FWS can, and regularly does, list animals and plants without first placing them on the Candidate List. As a resultthe Candidate List is regarded by many conservationists as a stall tactic by FWS.

Candidate species are assigned a listing priority from 1 to 12 based on the magnitude of threats they face, the immediacy of the threats, and their taxonomic uniqueness (for example, full species have higher priority than subspecies). The species’ listing priority dictates the relative order in which proposed listing rules are prepared, with the species at greatest risk (listing priority 1 through 3) being proposed first. Significantly, in the 2008 list, FWS determined that the ranking for the Red Knot should be raised from 6 to 3.

The rufa Red Knot, a reddish-brown shorebird slightly larger than an American Robin, migrates annually from Tierra del Fuego to its arctic breeding grounds, stopping to rebuild critical energy reserves by feasting on horseshoe crab eggs in Delaware Bay.

Only 14,800 Red Knots were counted in 2007 at the species’ primary wintering areas, a 15% decline from 2006, and a 75% decline from 1985. The results of several scientific studies have shown that a major reason behind this decline is a fall in the number of available horseshoe crab eggs due to overfishing of the crabs themselves, which are used as bait in conch and eel fisheries. This led FWS to conclude in their candidate review that, “The primary factor threatening the Red Knot is destruction and modification of its habitat, particularly the reduction in key food resources resulting from reductions in horseshoe crabs…”

“The U.S. Fish and Wildlife Service has once again confirmed that the Red Knot is increasingly threatened with extinction and deserving of heightened conservation measures, particularly immediate reductions in the commercial harvest of horseshoe crabs, whose eggs comprise the knot’s primary food source,” said Darin Schroeder, American Bird Conservancy’s Vice President of Conservation Advocacy.

The increased priority ranking for the species from 6 to 3 may speed its listing, but this could still be years off. “Too often species languish on the candidate species list and are not afforded the protections of the Endangered Species Act that we know work very well,” said Schroeder. “We urge the incoming administration to expeditiously act to list the species as the scientific research warrants.”

Only a Snowy

by Lanny McDowell on November 30, 2008

At the risk of getting lost in the crowd, we offer up our simple fare.  There was a snowy or two on Chappaquiddick last winter, but I have not seen one on the Vineyard for many a year.  The time is now.

Six of us left our two cars in the parking at Black Point, walked the boardwalk over the marsh and crested the barrier dune.  We had owls on the brain from third party sightings in the general area.  The collective intention factor was high on the meter.  The first call was a very distant Herring Gull on an inland sandbar.  However, between us and the sandbar, about halfway across the barrier beach ‘twixt Black Point Pond and the Atlantic was either a very robust and bright fence post or a Snowy Owl.  With binocs we thought there was movement.  People with 10-bys saw more movement; and then Soo’s scope was on it.  Ta-da!

The sight of six optics-encumbered human heads rising over the dunes was not an appetizing prospect for the owl:

In the afternoon I went back solo to another location and had the bird to myself, Mr. Canon and Stella, for a more intimate interview, for a session with a peregrine quite curious about the dog and photographer, and for the distant owl with Snow Bunting flurry shot.

Red Knot project update -

by Lanny McDowell on November 28, 2008

Here is a copy of an article I wrote for the Martha’s Vineyard Gazette that was published yesterday.  It  describes and updates the efforts of Global Conservation Alliance, a partnership of three birders looking for ways to reverse the demise of Red Knots and other shorebirds that depend on horseshoe crab eggs on the shores of Delaware Bay to fuel the last leg of their northern migration.  The actual published article is online at http://www.mvgazette.com/article.php?19303.

This is the issue I address on the Crusade page of this blog.  Please feel free to comment (in Comment field below) and suggest.

UNRAVELING THE RED KNOT DILEMMA by Lanny McDowell for the Vineyard Gazette 11/28/08:

  We had committed to spending the last week of May along the New Jersey side of Delaware Bay, on the beaches that stretch north from Cape May.  One of my two partners in this project, Porter Turnbull, had set up our first meeting at a service stop far down the Garden State Parkway. Our discussion was with a longtime fisherman who has been an advocate for commercial horseshoe crab harvesters.  The meeting outlined the complexities of balancing the interests of crab fishermen, shorebird researchers and the wildlife that served both. The meeting also answered our immediate question: where are the most shorebirds feeding on horseshoe crab eggs at the moment?  His answer was Moore’s Beach; and directions were noted.

 We went there straightaway, following a crumbling blacktop one-laner through vast marshes, one of us at the wheel, the other out ahead wading through enormous puddles and the tidal streams crossing the roadbed, feeling for deep holes underfoot that would snare our rental.  There was only one that deep and, fortunately, Porter found it, much to his surprise and up to his thighs in marsh water.

 We emerged from our rite of passage to deadend at an abandoned fishing outpost that remained only as shards of busted-up concrete and useless dock pilings.  A tidal estuary flowed into Delaware Bay between the mud banks of the marsh and the pebbled flats near the beach.  Shorebirds were flying in from the southeast as singles, in two and threes, and in small flocks.  The late light was striking from the west.  Off to the south along the sandy bayshore there were laughing gulls wading in tight feeding mobs.  The pebbled flats were covered with thousands of birds, all feeding actively and close together:  ruddy turnstones, dunlins, some semi-palmated sandpipers, some sanderlings and, most important to us, maybe one third of the east coast population of migrating red knots (Calidris canuta rufa), the reason we were there.

 The amazing annual cycle of migration for an adult red knot begins on a tidal mudflat along the coastline of Patagonia.  They fly north, typically to the northern shores of Brazil.  There they feed intensively, building up fat deposits to burn as fuel as they fly the next long leg over open ocean to the US, where almost all of them make landfall at Delaware Bay, a specific stopover area where fueling up for the last northward leg is top priority.  Dispersed over vast areas of the arctic tundra, they will mate, nest and hatch out young, which are precocial and quite capable of feeding themselves in the endless daylight. 

 Red knots are a large sandpiper about the length of a robin, but bulkier and longer-winged.  They are sometimes seen in passage on the Vineyard in small numbers, usually in late summer on flats interior to our south side barrier beaches, while much larger numbers gather at South Beach (off Chatham) and the Monomoy islands, staging for direct return flights to South America.  Red knot population declines have researchers puzzled and worried.  After tracking the radical drops in shorebird populations over the last thirty years, they fear that extinctions of this and other shorebird species are looming, a real possibility in even the next few years.

  The migratory flight segments of red knots run up to twenty-five hundred miles long, non-stop, eighteen thousand miles total in a year.  To power this kind of sustained flight at up to forty miles per hour they increase their body weight from fifty to one hundred per cent when sufficient food is available.  They even shrink certain digestive organs in the interest of trimming unusable weight.  At the end of those flights they are usually emaciated and exhausted … and very hungry.

 My interest in these incredible travelers began a few years ago when a friend of mine, an adman and writer on the Vineyard named Geoff Currier, gave me a book he had received as background for an advertising job.  It was called Flight of the Red Knot by Brian Harrington (with Charles Flowers), who happens to have long-standing ties with the Vineyard and a career in shorebird research associated with the Monomet Observatory for Conservation Sciences.  A couple of years later, another West Tisbury friend, Richard Cohen, suggested that he and I enroll in a shorebird monitoring program in Delaware.  We learned how to trap, handle, band, measure and weigh turnstones and knots, as well as how to read and interpret the leg bands of birds caught previously.  Then, two years ago in June, I was invited to go up to Lubec, Maine, by Porter Turnbull, who wanted me to meet a biologist friend of his, Norman Famous, his ornithologist mentor from college days.  We were all birders.   In the course of our stay there the precipitous declines in red knot numbers was discussed, along with the related problems that the horseshoe crab industry was enduring.  We wondered if some practical approach which went beyond the research efforts could be applied to the problem.  In other words, was there a way to directly stall or reverse the red knot declines; and could part of a solution be to supplement the available food sources at the Delaware Bay stopover?  It seemed an elegant solution, if it were actually doable.

 Researchers and activists had long been spearheading efforts to mandate the regulation or outright ban of commercial harvesting of horseshoe crabs in and around Delaware Bay, on both the New Jersey and the Delaware sides.  The over-fishing of the crabs for bait in conch traps and for medical uses is recognized as a direct contributor to the diminished abundance of eggs on the beaches where the shorebirds need them in great numbers to fuel their flight north in June.  Harrington estimates that a red knot will consume 135,000 eggs at this stopover.  In addition to the fat requirements for the flight up to the arctic, the birds may arrive to find a snow-covered landscape that is not yet warm enough to produce food for them, so they may have to live off reserves for another two weeks.

 An ad hoc committee, the Global Conservation Alliance (GCA), consisting of Famous, Turnbull and McDowell, was formed to save the planet.  Well, at the least we would sample the political waters of an issue that had pitted commercial interests against naturalist researchers and bird huggers; and we would look into the possibilities of finding and obtaining a supplementary food provision for the birds.  This would involve initiating some activity that would increase the food supply for the birds during a crucial time, provide an interim opportunity for the diminished stocks of breeding-age horseshoe crabs to recover, and find a way to integrate the fishing and naturalist communities in a process that is sustainable and mutually beneficial.  We also acknowledged to each other that we would be addressing only one of enumerable factors in a life cycle that literally spans the globe?

 Our first discussions within GCA had the nervous self-righteousness of the outsider:  Why are all those folks just studying them?  When are they going to do something? Don’t we already know they are dying off faster than we can keep count?  What if something bad happens in Delaware Bay, like an oil spill?  What if there’s a late snow on the breeding grounds?  Are they hunted for food in South America?  What if they are?  At the current rate of loss how many years are left?  Does anyone really care, besides us?  What if the horseshoe crab fishermen cheat on the harvesting bans?  What if the net effect of trapping and processing the birds for research is to stress them beyond recovery?

 When Norman joined us in Cape May he had a station wagon stacked with bags of fish-based food product which a subsidiary of Land O’Lakes produces to supply zoos. The Aquamax pelletized feed was the best manufactured food item we could find in terms of size, appearance and nutritional content, the closest to horseshoe crab eggs and what we hoped would appeal to ravenous shorebirds in a feeding frenzy.  A grant from the Marine Conservation Action Fund at the New England Aquarium paid for the product.  Bottom line, our trials did not have much success getting shorebirds to eat the food, in part because of limits placed on where we were allowed to deploy it and partly because the birds did not readily recognize it as a prey item.  The laughing gulls, however, really liked the food we spread on the beaches and would stand shoulder-to-shoulder to devour it until the last morsel was gone.

 The week was an unqualified success in other terms: our ability to assess the politics of competing factions, getting the lay of the land, the personal contacts we made and, especially, the resolve we came away with to pursue whatever combination of solutions seems most likely to contribute to slowing the demise of the shorebirds and restoring the egg-laying population of the struggling horseshoe crab, a beast that has been doing what it does for untold millions of years, in the waters of Delaware Bay and in the waters of Martha’s Vineyard.

 Where does the GCA partnership go from here, meaning what’s the plan for the spring of 2009?  Meetings with fish and wildlife personnel here in Massachusetts are ongoing and we are in touch with an expanding list of allies and interested parties from Virginia to Maine.The current best guess is that three strategies will emerge as the most practical and the most promising: find an available supplemental  food that red knots will eat in their natural context; rake the beaches holding the horseshoe crab eggs to turn over the top few inches to expose more eggs to predation by shorebirds; distribute food that will distract competing gulls to locations other than those where the shorebirds are feeding

on horseshoe crab eggs.  Any and all of these approaches will require funding, permitting and testing. That’s the plan that is taking shape.

The red knot project administered by Global Conservation Alliance, a non-profit organization, is looking for funding from private and public sources.  To read the 2008 project report, updates and contact info, go to the author’s website at LannyMcDowellAvianArt.com; find Blog and then the Crusade page.

Chilmark beaches: avian seasonal residents return

by Lanny McDowell on November 25, 2008

Yesterday, when the sun was still shining, I hit the beaches at Squbnocket and Lucy Vincent Beaches in Chilmark with an eye to documenting recent winter arrivals.

 

Sanderling swimming? Not really.

 

 

 

Most of the eiders in these five shots are the same birds.   I am wondering about splicing some of the 1X2 or 1X3 proportioned cropped shots end-to-end for a panorama of sea ducks.

 Birds of a feather …, or do they?  This drake teal was probably hanging with the saltwater crowd because there was new ice over most of the marshy section of nearby Squibnocket Pond. 

 

 

 

 

 

 

 

 

 

At Lucy Vincent’s there was first a pair of Harlequins.  Then the hen Harley morphed into a oddly plumaged hen Old Squaw (LTDU), which we rarely see this close to shore at this section of the island.  The f. Harley and the f. Old Squaw were buddies and cruised up and down the shoreline together.

 

 

 

Even though I have many shots of Harlequin Ducks,  I hate to miss an opportunity to photograph them when they are not too reluctant to be in (my handheld) camera range. 

Last, but not least, the Purples are back for the season:
