Ocean City, NJ is a resort town in South Jersey on an island which can be reached via a causeway. Driving on the causeway, before arriving in Ocean City, there is a turn-off for a Welcome Center. From a sidewalk right next to the center, every Spring and Summer it is quite easy to take pictures of Herons, Ibises, Egrets, and many other birds that fly in from the South to breed and raise their chicks. The sidewalk is almost as tall as the rookery trees, so one can look down on their nests and watch activities from breeding to incubating and finally fledging just before the birds migrate South. The birds seemed unperturbed by all the human lookers and photographers.
I missed going there last year, and this year I only managed to get to the rookery this past weekend. It is late in the season, but I still saw a Yellow-crowned Night Heron nest with unhatched eggs. The tired-looking mother had just stood up to scratch herself.
After some more preening, she tidied up the nest.
Then she sat down and resumed incubating. The eggs should be hatching in a few more days.
