The commonly heard flight call of the Greater Yellowlegs is usually repeated three times (May, NJ).
When excited the call may be repeated in longer sequences (Mar, NJ).
The same call of the Lesser Yellowlegs is usually repeated only twice and is higher, with a less ringing tone (Mar, NJ).

Short-billed Dowitchers are talkative while feeding, but these calls do not carry far, giving rise to the reputation that they are quiet while feeding. A parabola picks up these quiet calls, which are very similar to those of Semipalmated Sandpipers. I am confident that these were made by dowitchers as no other species were nearby. The calls average lower than those of Semipalmated Sandpipers, and are usually single-peaked, whereas many calls of Semipalmated are double-peaked. (May, NJ).
Semipalmated Sandpiper feeding calls for comparison (June, NJ).
Short-billed Dowitchers give a rapidly repeated tu-tu or tu-tu-tu, also heard in flight, faster than the calls of yellowlegs. The calls at the time of take-off (at 7s) are different and can be confused with the calls of Long-billed Dowitchers (May, NJ).
