Semipalmated Plover: Seashore Sunday

I woke up this morning (Sunday) and realized that I didn’t post a Seashore Saturday! I lost track of what day it was. So here’s another Seashore Sunday. This week’s bird is one that I’ve been seeing a lot of lately: the Semipalmated Plover. I saw this bird on my recent trips to Cape May and Edwin B. Forsythe NWR.

Semipalmated Plover (Charadrius semipalmatus)

Description:

Semipalmated Plovers are about 7.25 in length. They have brown upperparts, white underparts, and orange legs. They have a distinctive dark breast band, as well as dark cheeks. The base of their bill is orange while the bill tip is black. They are smaller than the similar-looking Killdeer, who have a double breast band.

Diet:

Mainly insects, but also marine worms and crustaceans. Semipalmated Plovers forage by running in short spurts and pecking the ground when they spot food. Sometimes they shuffle their foot in the ground to startle prey into moving.

Breeding and Nesting:

To attract a mate in the air, males will flying in circles using slow wingbeats over their territories while calling. Another technique is to fluff his feathers, spread his tail and wings, crouch down, and call excitedly. Semipalmated Plovers build the nest on bare gravel or sand and line it with natural materials.

Both sexes incubate usually 4 eggs for 23-25 days. The downy young leave the nest shortly after hatching and feed themselves while being watched by the parents. Young plovers’ first flight occur between 23-31 days after hatching.

Sounds:

Two-note whistle: tu-wee!

Fun Facts:

  • “Semipalmated” refers to the fact that they have partial webbing in between their toes.
  • Semipalmated Plovers are the most numerous of the small plovers.
  • Like the Killdeer, Semipalmated Plovers use the “broken-wing display”, where they pretend to be injured to lure predators away from their chicks.
