Avian material from Rancho del Oro, a Pleistocene locality in San Diego County, California

摘要

Late Pleistocene avifaunal material from a construction site in Oceanside, California is described. The material includes 77 bones from 21 species, only one of which (Podiceps parvus) is extinct. Two previously described Pleistocene species (Oxyura bessomi and Bucephala fossilis) are placed in extant species. The first fossil record for Phalaropus lobatus is recorded.
