The bird collection at the Natural History Museum Basel includes 36 types. Most of these were collected between 1893 and 1912 during research expeditions.
The 36 type specimens come mostly from the two expeditions by Fritz and Paul Sarasin to Sulawesi (formerly Celebes) in 1893 – 1896 and 1902 – 1903 as well as from the trip to New Caledonia undertaken by Fritz Sarasin and Jean Roux between 1911 and 1912. Other types come from Celebes and were described by Adolf Berhard Meyer and Lionel William Wigglesworth. The species described by Fritz Sarasin himself come from New Caledonia.
Our bird collection also includes several examples of specimens that have been exchanged with other museums. Other specimens come from expeditions that brought back new species for description. They include possible paratypes. Their status is still to be determined.
