In search of avian wonders out of the ordinary, we turn now to the sparkling shores of the Delaware Bay. A large expanse of sandy beaches and saltwater marshes along the New Jersey side of the bay attracts many feathered marvels.
I went to the Bayshore one sunny May day to see migrating shorebirds. I’m easily distracted. A side trip to Cape May Point State Park occupied most of my morning.
Alongside the road, a gravel, shell and grass area serves as a parking lot for visitors. It also serves as a nesting area for the local Killdeer population. We didn’t see this little mother when we pulled in; three feet to the right would have been disastrous.
The Killdeer was incubating eggs right there in the parking area. She was none too happy about our near-miss and our presence, so I took my photos quickly and left her in peace.
And comical. Heads down to feed, the gulls resembled a tail-feathered basket-weave fence. One poor guy in the middle had a complaint.
The stars of the show were the Red Knots. This little shorebird travels immense distances every year from wintering grounds at the tip of South America, to breed in the far north. Along the way, having lost much of its body weight to the rigors of flight, it joins other long-distance migrants at the Delaware Bay, to feast upon the fat-laden eggs of the horseshoe crab.
Horseshoe crabs come ashore to lay their eggs at the same time the shorebirds arrive. Unlike this unfortunate crab, most remain right side up and survive to breed another year. Their numbers are dwindling though, due to sustained over-harvesting. Bad news for the shore birds, especially the Red Knots.
There is concern for a number of shorebird species, but the Red Knot population is in the worst shape. In an attempt to protect and conserve these birds, scientists have been tracking their numbers and movements. Spotters were posted at Reeds Beach, recording band colors and numbers. Only time will tell if conservation efforts succeed or fail.
This Red Knot has been captured, weighed and released, and wears some distinctive jewelry to commemorate the experience. Green is the color used for birds in the United States. I saw orange bands as well. Those birds were banded in Argentina!
From Argentina to New Jersey, and on to the far north, shorebirds undertake extraordinarily long journeys, twice, every year. The horseshoe crabs along Delaware Bayshore provide the fuel they need to keep going. Its sandy shores are the perfect places to savor the wonder of these extraordinary birds.
