Great Bay Blvd 5/12--Red Knot, Common Tern

Red Knots
Mid-May is the time to look for Red Knots, and you don't have to go to the Delaware Bayshore in Cape May to find this threatened species. It isn't the spectacle that you'll find there, but this time of year, the beach at Great Bay Inlet is a reliable spot to find a good flock of knots, and if you're a lister, you only need one. 

This morning I counted 38 birds jabbing at the mud during low tide. The controversy in Cape May is always about limiting the horseshoe crab harvest (their blood is used in medical tests and their bodies as bait), since the Knots depend on the crab eggs for their nutrition when they stop over on their long journey from South America to the Arctic. There are horseshoe crabs at Tuckerton, but not in great numbers so I have to suppose that the Knots were making do with the invertebrates that the Dunlins and turnstones were feeding on too. 

Terns were flying over the bay, but I'm very bad at distinguishing Forster's Terns from Common Terns on the wing, so I was happy when I was able to compare two pairs roosting on pilings by the Rutgers Research Center. The Common Terns have the redder bills, the shorter legs and this was clear in the scope. 

Yellow-crowned Night-Heron
I was also happy to find my FOY United States Yellow-crowned Night-Heron on the way down to the inlet. It was in the night-heron roost at the first bridge along with a few Black-crowned Night-Herons. I'd seen a few at Rio Lagartos last month, but this was the one that really counts. 

And as a little bonus, from that same bridge I spied in the distance a Hudsonian Whimbrel in the marsh, a much more satisfactory look than the flyover trio at Cedar Bonnet Island on Sunday.
