All of the African mammals gathered around the watering hole in the Hall of African Wildlife were collected on an early research expedition let by Childs Frick to British East Africa and Abyssinia (now Kenya and Ethiopia).
The official dates of that expedition were 1911–1912, and we can track almost all these specimens to that trip. However, in 1909–1910, Frick took an exploratory trip to part of the area covered in 1911–1912 to scope it out and probably collected the giraffe on that trip at the train stop in Voi.
