Abstract

CESTARI, César. Foot-trembling behavior in Semipalmated Plover Charadrius semipalmatus reveals prey on surface of Brazilian beaches. Biota Neotrop. [online]. 2009, vol.9, n.4, pp.299-301. ISSN 1806-129X.  http://dx.doi.org/10.1590/S1676-06032009000400036.

Foot-trembling is a foraging technique normally performed by plovers and lapwings. It exposes preys, and may increase the likelihood of capture. Currently, no detailed description of this technique is available for the Semipalmated Plover Charadrius semipalmatus. This article described the foot-trembling behavior during wintering of this species in southeastern Brazilian beaches.

Keywords : foraging behavior; foot-trembling; Semipalmated Plover; shorebird; southeastern Brazil.
