The Natural History Museum of Denmark (NHM-DK) is a research centre associated with the University of Copenhagen. Their library has begun the digitization of the field notebooks, journal publications and books held in their library, some of which have significant historic value. The information in this dataset comes from a particular classic literature compilation digitized called_ ‘Birds at the Danish Lighthouses, 1883–1939’ (In Danish, ‘Fuglene ved de danske Fyr, 1883–1939’). 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 cataloged 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.
