This extraordinary bird, especially when in flight, can hardly fail to impress even the most casual observer. Usually only one or two are seen as they skim the surface for fish, with the tip of the lower mandible cutting through the water. They also wade in shallow water, jabbing at the fish scattering before them. Compact flocks may be seen flying in unison, wheeling in one direction and then another -- showing first the jet black of the wings, then the gleaming white of the underparts. They are especially attracted to the sand fill of newly dredged areas; such places sometimes contain colonies of up to 200 pairs. These sites are usually temporary, abandoned as soon as too much grass appears.</i>
