The common sandpiper (Actitis hypoleucos) is a small Palearctic wader. This bird and its American sister species , the spotted sandpiper ( A. macularia ), make up the genus Actitis . They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize .
Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but the form and length are variable. They are small to medium-sized birds, measuring 12 to 66 cm (4.7–26.0 in) in length. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food.

The waxwings are a group of birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name. These are arboreal birds of northern forests. They live on insects in summer and berries in winter.
This bird looks similar to the widely sympatric sharp-tailed sandpiper ("C." acuminata), which is not a member of the stint clade however. The pectoral sandpiper is a largish calidrid (21 cm (8.3 in) in length, with a wingspan of 46 cm (18 in)) [ 4 ] with a grey-brown back, brownest in the summer male, and grayest in winter.
