The Early and Middle Pleistocene Avifauna from Porcupine Cave

The avifauna fossils represent at least 45 taxa, and include species reported as fossils for the first time in North America (e.g., the curlew Numenius madagascariensis or Numenius arquata). This chapter examines avian fossils found in the Porcupine Cave. Nearly 200 avian fossils were recovered from the deposits. The new records from Porcupine Cave add considerably to the diversity of birds known from the region and provide important information on the composition of avian communities in the Rocky Mountains of Colorado.
