We studied some aspects related to breeding of two subspecies of Wilson's Plover (Charadrius wilsonia beldingi and C. w. cinnamominus) at two nesting sites in Colombia, one in Sanquianga National Park on the Pacific Coast, and the other in Isla de Salamanca National Park, on the Caribbean Coast. Both subspecies breed from March through August, with an approximate clutch size of three eggs, and an incubation period of 21-22 days. We found four nests of C. w. cinnamominus in Salamanca and 35 nests of C. w. beldingi in Sanquianga. The nests found in Salamanca were located close to vegetation and included material only in their bottom, in contrast to nests found in Sanquianga, which were often located near objects brought by the sea in sandy beaches with scant vegetation, and only included material in their periphery. This study highlights the importance of Sanquianga National Park as a breeding site for Wilson's Plover in Colombia.
