Upland Sandpiper (Bartramia longicauda)
Long Whistle: Unique and unforgettable. A long drawn out whistle in several parts. It starts low and gurgling, or trill like, then rises up the scale and the tone becomes a clear whistle.
This is followed immediately by a second whistle that rises and then falls again, ending up down where the first whistle started. The overall effect is very reminiscent of the classic "wolf whistle"
Both male and female give the long whistle, but the male more frequently once nesting has commenced (Buss et al. 1939).
The long whistle is sometimes given nocturnally (Houston et al. 2001).
