The question should really be what don’t they eat in the world of insects and diminutive sea creatures. Over the past two summers I have filmed PiPl eating every kind of beach dwelling crawly insect and marine life imaginable.
Piping Plovers eat freshwater, land, and marine invertebrates. Their general fashion of foraging is to run, stop, peck, repeat, all the day long, and during the night as well.
Run, Stop, Peck
When foraging along the wrack line and up to the dune edge Piping Plovers eat insects, both alive and dead, including ants, spiders, grasshoppers, crickets, and beetles, along with insect larvae such as fly larvae. Foraging at the intertidal zone, Piping Plovers find sea worms, tiny mollusks, and crustaceans, as well as crustacean eggs.
When the chicks get a little older they will learn how to do a sort of foot tamping technique where they rapidly shake their feet in the sand to stir up crustaceans. I have yet to see our chicks do this, but soon enough.
The purpose of discontinuing to rake the beach to help the Piping Plovers is twofold. Not raking in the nesting site creates a habitat rich in dry seaweed and dry grasses, which attracts insects, the PiPl food on dry land. Secondly, raking in the vicinity of the Plovers after they hatch can be deadly dangerous to the chicks. Not only is there danger of being squished, but also, they can easily become stuck in the impression in the sand made by the tires of heavy machinery.
This morning I had a disagreeable conversation with a woman about her unleashed puppy. She feigned lack of knowledge about the dog ordinances, but aside from that, she informed me that her large puppy would be “afraid” of a chick. And there seems to be a frustrating lack of understanding about where the chicks forage. We can only share again that the Piping Plovers, both adults and chicks, feed from the dunes’s edge to the water’s edge, and everywhere in between. Sunrise and sunset are not safe times to walk dogs on the beach because Piping Plovers forage at all times of the day, and into the night. Adult birds can fly away from a person or dog walking and running on the beach, but a shorebird chick cannot.
