“The Common Sandpiper’s (Actitis hypoleucos) (above) classical call is made often when the bird is flushed and we would have heard this often. Wells (1999) describes this as ‘a shrill, pipping, pwee-wee-wee-wee‘. Van Gils, Wiersma & Kirwan (2017) in HBW describes a longer song which I am yet to hear.
“On this occasion I heard another type of call. This was a shrill, single, drawn-out note made at 1-2 second intervals, repeatedly. At the time the calls were made the bird did not appear to be in any distress. It had been feeding with other waders nearby – another Common Sandpiper, a few Wood Sandpipers (Tringa glareola), two Oriental Pratincoles (Glareola maldivarum), two Little Ringed Plover (Charadrius dubius) and a single Lesser Sandplover (Charadrius mongolus schaeferi). None were viewed as threats. I am not sure what to make of the call, but suspect it is some type of advertising or contact call.
