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 1,212 records. 2 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. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

All the data was collected in Europe, Denmark in Lodjberb Fyr (56.82343, 8.26789)and Hostholm Fyr (57.11267, 8.598575).

Taxonomic Coverage

From the species identified, 18 did not have species name and 10 were not identified. About 100 different species were observed from the 1212 individuals. There were 14 orders, 36 families identified all from the kingdom Animalia, Phylum Chordata and Class Aves. Passeriformes were the most significant dominant order and Charadriiformes were the second most dominant order. Under family Turdidae were the most dominant, fololowed by Muscicapidae and Scolopacidae. When it came to species Sturnus vulgaris had the highest individuals, followed by Alauda arvensis, and Turdus iliacus.

Temporal Coverage

Sampling Methods

The data contains a digitized literature compilation for the project, recorded in books for two lighthouses. These lighthouses were used by several species of birds during the nights of the bird migration period from the years 1886 through 1939. The presence and activities of these birds were recorded, especially by the keepers of these lighthouses who also collected specimens that were sent to the museum in Copenhagen. These birds were carefully preserved and catalogued by collection managers at the museum and the specimens can still be found there today.

Method step description:

1. Two library staff members trained in the use of the library scanner to scan delicate volumes digitized the literature. Text was extracted from the scans through OCR (Optical Character Recognition) software. Transfer of data from the scanned PDFs into spreadsheet format was done through gaining access to the files stored in the museum intranet (private network). Taxonomic checking was done through catalogue of life and GBIF Nameparser, data curation and cleaning was done using excel and open refine, format and transformation was alo done through open refine. All this was done in excel and Open refine and software such catalogue of life.
