The collections in the Division of Ornithology are comprised of about 2,400 prepared specimens. Collecting emphasis has been on the acquisition of skeletal material along with the more traditional skin-skull/study skin specimens. As a result, the collection includes significant holdings of post-cranial osteological material. The ornithological collection is searchable on Arctos. Although taxonomy, specimen identifications and associated data are constantly reviewed, errors such as outdated names, mistaken identifications and erroneous collection event information do occur in our database. Investigators should verify identifications by examination of specimens.
