Evidence of conspecific nest parasitism and egg discrimination in the sora

Sora (Porzana carolina) Science Article 2


Conspecific nest parasitism (CNP) is relatively frequent among precocial species and several hypotheses for this patter have been suggested (Rohwer and Freeman 1989, Lyon and Eadie 1991, Sorenson 1992). I report here observations made at the nest of a Sora, Porzana carolina, which suggest both the occurrence of CNP as well as very fine egg discrimination in this species.
