Some Semipalmated Sandpipers (Calidris pusilla) feed among Dunlins (Calidris alpina) in mud flats at Anahuac National Wildlife Refuge, in Chambers County, TX, USA. The smaller Semipalmated Sandpipers give the larger Dunlins plenty of space.
The 3 Dunlins in the video have different plumage. the first one has the black belly and rusty back feathers that gave the bird its earlier common name, the Red-backed Sandpiper. One of the two others later in the video has nonbreeding winter plumage, and the other has plumage in between the other two, with the beginnings of black belly and red back.
