Sounds and Vocal Behavior

Song, given only on breeding grounds, consists of a long, muffled trill . The typical call note, given in flight (especially when flushed), is softer and simpler than the equivalent vocalization of the Pectoral Sandpiper (Calidris melanotos), being frequently rendered as pleep or wheep, and usually given in a short twittering sequence that can even recall a Barn Swallow (Hirundo rustica). Also heard are various low grunting noises and a subdued, repetitive ueep-ueep . See Agonistic Behavior: Breeding Territory Maintenance.

None described, but some wing-whirring during courtship and territorial flights likely, as in Pectoral Sanpiper, Calidris melanotos.
