Description
MVZ egg and nest specimens are catalogued separately from traditional specimens (skins, skeletons, fluids). The egg and nest collection contains over 14,000 items, including over 12,800 egg sets, 220 nests, and 900 egg-nest combinations. The size of this collection ranks it as one of the largest such collections in North America. Eggs of nest parasites (e.g., cowbirds) are present in approximately 120 sets, and 150 egg sets or nests are associated with catalogued bird specimens. Eggs in this collection range in size from the tiny eggs of hummingbirds (0.2 grams) to the gigantic eggs of the extinct elephant bird (9 kilograms). Approximately 80-90% of the specimens are accompanied by original collector data slips and by photographs of sets taken in the museum, both of which are digitally linked to the record online. These data slips contain information on collecting locality, date, clutch size, incubation, identification, nest composition, and nest placement.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 15,012 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section.
