The bird collection at the NTNU University Museum goes back to approximately 1800. It consists mainly of objects from the norwegian mainland, but also has a small historic collection of birds collected between 1860 and 1910 from all over the world (app. 450 objects). This historic collection includes many species which today are endangered, threatened or distinct. The collection consists mainly of mounted objects, but there are also some skeletons, skulls and objects preserved on ethanol. From the latest years there are also preserved tissue samples of almost all new objects. These samples are stored at -80 degrees C. The geographic coverage of the objects in this collection is mainly Norwegian mainland. Within Norway mainland the majority of objects collected origins from central Norway.
