The Red Knots “Vote with their Wings”

Share

Clive Minton is fond of saying, “the knots vote with their wings” as a way of saying knots concentrate in the best places for knots. Of course it’s true, animals move to the habitats they find most suitable, nature leaves little room for anything but. Sometimes however, animals use a habitat only because they have little choice — in other words, they are making the best of a bad situation. The job of a good wildlife biologist is to understand the difference. Unfortunately, it’s often not obvious. In all the places studied by this author — Tierra del Fuego, the…

19,077 Red Knots Observed in New Jersey

Share

Despite the threatening forecast of a cold drizzle and strong winds, our team persevered to complete the first bay-wide count of this season. On the New Jersey side of Delaware Bay, we counted 19,077 red knots – the most seen in the state in a decade. With Delaware’s shorebird team recording 2,000 knots along their entire shoreline, the total knot count of 21,077 is not far from the 24,000 seasonal maximum of the last three years. This is good news in either of two completely different ways. One explanation is that perhaps most of the knots have already come to…

13,000 Red Knots on New Jersey’s Delaware Bay

Share

We had about 13,000 knots on the New Jersey side of the Delaware Bay (an additional reported 2,000 on the Delaware side of the Bay). Yesterday, we suffered strong NW winds in excess of 20 kts and the birds virtually disappeared. Our daily survey turned up about 6,000 knots, the rest we suspect, finding refuge in Egg Island and Goshen Marshes or with a flyover to Delaware. We will know where they went today. The team will comb the Bayshore for shorebirds with a coordinated ground, boat and aerial survey. The birds gain weight in good time and we expect…

2015 Shorebird Migration and Horseshoe Crab Spawn on Delaware Bay

Share

Thousands of shorebirds now fill Delaware Bay’s beaches and marshes in a determined effort to regain lost reserves with free-for-the-taking fatty eggs of the horseshoe crab. The crab spawn began ten days ago and has gained momentum over the last week as the volume of eggs grows like a well-funded savings account. The eggs surface as each new female crab digs up egg clusters laid by other crabs or as wind-driven waves pound the always-fluid sandy beaches. At least 8,000 red knots slowly get fat on the eggs scattered on New Jersey’s Delaware Bay beaches.   Both crabs and birds…

Delaware Bay Shorebird Project Continues for 2015 Season!

Share

The value of a shorebird stopover like Delaware Bay can be seen in the shaky cam movie by this author.  Red knots – some recently arrived after a grueling 6,000-mile flight over 6 days of continuous flying – arrive on the Bayshore desperate for food. Over the last 10,000 years, the species has evolved to fly directly to the Bay to feed on the eggs of the horseshoe crab. The 450-million year-old crab – which is actually in the spider family – crawls ashore and lays pin-sized eggs about 6 inches deep in the sand. When there are many crabs, as…

Fortescue and Thompson’s Beach: “It’s all labor”

Share

In the video above, Humphrey Sitters counts 16,000 red knots on Egg Island Point, just east of our new beach. The flock is the largest concentration in the hemisphere. The construction of Fortescue Beach has finally reached that early stage known to most people in construction where they say “it’s all labor”. The early logistical problems have been ironed out and our goal is simple, to get as much sand onto the beach as fast as is possible. On Tuesday and Wednesday, H4 hauled over 4000 tons of sand. The beach gradually takes shape. Boomer Huen and Eric Johnson use…
