Description
The bird egg collection at the Natural History Museum, Agder University, holds 1190 journal numbers of single eggs or clutches, but also a substantial number of eggs not yet digitally registered. The majority of bird eggs is a 20+ years series of Kestrel (Falco tinnunculus) eggs from SE Norway (687 entries with more than 1100 eggs). Each entry specifies conditions for collecting (single egg from clutch, whole clutch, failed, abandoned or unhatched eggs), date and locality, total clutch size and number of chicks, collector and determinator. Weight, length and with measurements are also given for a majority of the eggs.
