20  Years of Conservation and Science in Delaware Bay: In Dangerous Territory

Four days ago, the shorebirds of Delaware Bay could look forward to a bright future. But in the last week their chances for survival and good production have diminished.  In fact they are as dismal as the cold drizzle pockmarking the murky water in front of our house in Reed Beach. The following two graphs tell the story.  We captured red knots on May 12 and 16th  that showed a normal although not spectacular progression.  Than we made a catch of knots on the 19th and again today on the 23rd and in total they gained only 2 grams of…

20 Years of Conservation and Research on Delaware Bay – The Importance of water temperatures, windstorms and shoals

As we begin our field work on Delaware Bay shorebirds, our 21st season, oddly enough we are once again faced with extraordinary circumstances.   As usual, the birds, after various flight of up to 6  days of nonstop flying,  arrive in emaciated condition.   For example in one catch this week we caught several red knots at around 86 grams far lower than it normal weight of 130 grams.  Putting that into perspective, a women of 145 pounds would tip the scale at 93 lbs while a male of 175 lbs at 113 lbs!  In other words these birds are…

20 Years of Shorebird Conservation and Research on Delaware Bay

A Monumental Work of Conservation This year marks the 21st year of the Delaware Bay Shorebird Project. As one of the longest running shorebird conservation projects in the world, the only one of its kind in the US, we wanted to memorialize this monumental work. To do so we convened a daylong series of presentations by scientists and managers from all over the world who have worked on the bay.  Here are the abstracts. They are worth a look by nearly anyone interested in shorebirds and Delaware Bay.   DelawareBay_Workshop_Program&Abstract_CWF The presentations ranged widely. We heard talks diving deep into the…

Our Brazilian Expedition – Trapping Shorebirds in Panaquatira

The capture of Arctic nesting shorebirds first brought us to Brazil in 2013.  We also brought 125 geolocators and caught both ruddy turnstones and red knots, attaching 85 on the former and 30 on the latter.  But we also came to create a new perspective on shorebirds in this place, one of the most important shorebird habitats in the world. For all intents and purposes, shorebird work in this area started In the mid-1980’s, when Canadian biologists, Guy Morrison and Ken Ross surveyed from an airplane, the entire coast of South America.  In this monumental and dangerous survey, they established…

Our Brazilian Expedition – The Rights of Traditional Communities

Over the last few days of our expedition, we left the state of Para and flew to Sao Luis in the adjacent state of Maranhao.  There we begin the next phase of our work, trapping red knots, ruddy turnstones and other species, as we have done since 2014.     Traditional Communities Have Rights But prior to leaving Para, while we stayed in the village of Apiu Salvatore, the fishermen asked to meet with Max.  He hadn’t planned it, so at first, the reason was unknown. The fishermen of the village knew Max represented ICMBio, and that Apiu Salvatore fell within…

Our Brazilian Expedition – Going to the heart of the Mangrove and Beach Ecosystem

It took us long into the night to reach our next port.  We went from the relatively populated area of Braganca to the dark heart of this coastal region of Viseu.   In three trucks, we caravanned through a maze of remnant tropical rainforests, cattle pasture and impenetrable second-growth woodland.  Along the rain-slicked red clay road, small and desperate looking towns popped out of nowhere always looking like the past was a better day. The road cut through countless mangrove forests that define this region.  We reached Viseu too late to do anything but find a place to stay the night….

Our Brazilian Expedition – Conducting a Scientific Investigation in a Tropical Wilderness

  Tough Conditions for Scientific Investigation   It’s hard to imagine the difficulties of people living at latitude 37 degrees north when coming to the equator in northern Brazil. It challenges even the best-prepared field investigations.  But after three days our team has not only acclimated but accomplished surveys in two separate estuaries.     The tide cut short our first day in the field.  High tide persisted longer than we expected and our survey must take place when birds forage.  Shorebirds typically forage until 1 to 2 after before high tide and start again 1-2 hours after, usually resting…

Our Brazilian Expedition – investigating the plight of shorebirds and rural people

We leave a cold and dark NJ with mix feelings for our destination tropical Brazil.  It will be warm and sunnyish –  forecasts predict drenching thunderstorms threatening us every day of our trip.  We will explore a very new place, the ocean coast of Para, a largely unsurveyed coast known to be a wintering shorebird mecca.  At the same time, we will undergo trials experienced by few biologists.  Zeke is prevalent in Para, but recent cases of malaria are equally alarming.  Of course one must be ever vigilant for food and water pathogens.  Last year I developed food poisoning ending…

Having Faith in Action on Climate Change?

What hope do we have now? A Trump presidency has so many implications for our world, it would be hard to know where to start. For at least half the country it would be a path of fear, lost ideals and calamities. But of all potential misfortunes that could befall us,  the worst will almost certainly ride behind all the others. The delay could make action to solve the problem of global warming too little too late. Climate may defeat us. Soon the string of climate firsts will add up to a national awareness. The unprecedented and ferocious floods,  fires, tornadoes,…

Why Not Climate Change?

    Despite its nastiness, the presidential election has served to educate the American public in several unexpected ways. The influence of a male-dominated culture on women has been exposed and the impact is still growing much to the dismay of the Donald, Bill Cosby and thier kind. The tragic targeting of Afro-Americans by law enforcement was important before the election but it it has now grown into an important political issue and a national movement.  Last month a spokesperson for the National Association of Police Chief offered a seemingly sincere and unprecedented apology. But one thing this election has not…

the birds lift away to the arctic

On our final effort to trap shorebirds on Delaware Bay, we had the remarkable opportunity to watch sanderling and ruddy turnstones lift off for the Arctic. We first saw them feeding on the wave-tossed shoreline within the protected area in Villas; 1500 birds weaving as a single thread 5 deep with the contours of the wave, acting like a flying flock on the ground. Then a disturbance, a crow flying low down the shoreline and 2000 birds fill the sky.  Most settled again but one group of about 300 flew more with greater determination than the rest. Still low but…

a shorebird paradise lost

We conducted our first bay wide count of shorebirds on Delaware Bay and the results suggest we are rapidly approaching the peak number of shorebirds. Last year we counted 24,700 knots and 16,000 ruddy turnstones. This year’s counts are lower because it’s early, but still over 20,000 knots and 16,000 turnstones, 10,000 sanderling have stopped over in the bay. These promising results are preliminary, but it seems we are getting close to our peak population of red knots and at the peak of the other two species – if populations are similar to last year. Bird condition also looks promising….

Valuable Creeks and Shoals

In spite of the very spotty horseshoe crab spawn, the shorebirds on Delaware Bay seem to be gaining weight on schedule.  Below you will find a graph composed of the average weights of all the red knots by our team for the last 20 years. The curve is the result of combining all the data we collected and shows the sweet spot for most knots. As they arrive they take time to gain weight but after about 5 days they start gaining weight rapidly.  After the 26th or so, birds start reaching the critical weights necessary to safely reach the…

Shorebirds out in the cold

It’s well known that the Delaware Bay shorebird stopover depends on the horseshoe crabs.  Few know that the Delaware Bay is a near perfect horseshoe crab habitat. There are many places on the eastern seaboard where horseshoe crabs breed.  Most are too small to provide sustenance for energy starved shorebirds.  Places like Cape Romain Refuge in South Carolina, have enough horseshoe crabs so that one breeding female unearths eggs of another and thus lays out a tidy meal for shorebirds.  But the areas are small and at this time unimportant to the population of shorebirds. Most of the others are…
