NESTING SUCCESS AND SURVIVAL OF VIRGINIA RAILS AND SORAS

Sora (Porzana carolina) Science Article 1 abstract Lack of estimates of nesting success and annual survival of North American rails limits our ability to monitor rail populations, regulate harvest levels, and institute recovery programs. We here present Virginia Rail (Rallus limicola) and Sora (Porzana carolina) population trends from Breeding Bird Surveys (BBS) throughout North America

Evidence of conspecific nest parasitism and egg discrimination in the sora

Sora (Porzana carolina) Science Article 2 abstract 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).

Grey-breasted Crake (Laterallus exilis) Science Article 1 abstract We provide the first documentation ofLaterallus exilis in Costa Rica. Because of its secretive nature, little is known about this species. We describe the coloration of itssoft parts and contrast its vocalizations with those of L. albigularis, a common and sympatric congener. In Costa Rica, L. exilis […]
