We visited South Cape May Meadows with friends last week and say a great assortment of birds, (including the Glossy Ibis above:,  butterflies  and turtles (three kinds).

Here's an assortment.

I took this shot yesterday morning, from a great distance. No one really got a great view, but I did get this photograph. What is it? 

It's hard to comprehend the thousands of Red Knots and Semipalmated Sandpipers feeding on Horseshoe Crab eggs at Cook's Beach and shoreline to the north, but worth a visit in mid- to late May.

Two patches of shoreline to the north were wall-to-wall Red Knots. Tons of other birds as well -- terns, Ruddy Turnstones, Sanderlings, Spotted Sandpipers and gulls.
