The Birds at two Danish Lighthouses - Lodbjerg Fyr and Hanstholm Fyr - from 1883 to 1939, is a compilation of occurrence data recorded in transcribed records of keepers transcribed into books (In Danish, ‘Fuglene ved de danske Fyr, 1883–1939’).

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.

Geographic Coverage

Two lighthouses along the coast of Denmark.

Bounding Coordinates South West [54.623, 7.866], North East [57.81, 12.81]

Taxonomic Coverage

In the period 1883-1939, there were 45 lighthouses and lightships functioning in Denmark. 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. Observations of weather conditions during the nights when birds were observed by the keepers were also documented.

Class  Aves (Birds)

Project Data

This is a sample database of a larger digitisation effort from the Natural History Museum of Denmark (NHM-DK)to make field notebooks, journal publications and books held in their library, some of which have significant historic value, available online.

Title Birds at two Danish lighthouses from 1883 to 1939
Funding Danish Govermnent to the National Library Association
Study Area Description Two lighthouses in the west coast of Denmark.
Design Description The Natural History Museum of Denmark (NHM-DK) is a research centre associated with the University of Copenhagen. Their library is member of the national library association, that received state funding to make available online the resources held by its members. The NHM-DK, after consultation followed the suggestion from the Head of the management office of the Nordjylland National Park to digitized the classic books‘Birds at the Danish Lighthouses, 1883–1939’ (In Danish, ‘Fuglene ved de danske Fyr, 1883–1939’), and more specifically the data from two of them(Lodbjerg Fyr and Hanstholm Fyr). The information would serve for an on-site exhibition project.

Sampling Methods

Study Extent Record of birds at two Danish lighthouses(Lodbjerg Fyr and Hanstholm Fyr)in the period 1883-1939.
Quality Control The museum library staff carried out the digitization of the literature. The text was extract through OCR (Optical Character Recognition) software. Volunteers from the Copenhagen Ornithological Society (COS) transcribed the OCR data into pre-defined spreadsheets. Staff and collaborators from the Bird Department of the University of Copenhagen made the taxonomic checking, data curation, and any needed cleaning, formatting and transformation. The latter oversee the entry of metadata for the published dataset which was done by the DanBIF Node.

Method step description:

  1. Data extracted from the books were translated into English. These were the scientific name as appearing, common name(s) in Danish as appearing, name of the lighthouse, date of the observation, the number of observed bird, their sex and life stage and the book reference. Any remark was also noted. Added later, was the current name of the species and its higher taxonomony (using API from GBIF through OpenRefine),the geographic coordinates (confirmed using InfoXY) and the URL of the digitized book page (based on the host server). Transcribed records were also verified for possible typing mistakes and other inconsistences.

Additional Metadata

Purpose This is a collaborative effort from the Danish Government to digitalise and make freely biodiversity data available from books, field notebooks and journal article held in public library across the country. The Nordjylland National Park is using these specific occurrence data recorded in books from two lighthouses (Lodbjerg Fyr and Hanstholm Fyr) for an on-site exhibition project.
Maintenance Description No mantainance is expected, unless errors are reported.
