Historical records of bird surveys on Sumba are grouped into two periods based on Indonesian independence events. Namely, before and after.
In the pre-independence phase, bird exploration was first carried out in the mid-18th century. The naming of the Cacatua sulphurea citrinocristata by Fraser in 1844 and Larius roratus cornelia by Bonaparte in 1853, shows that at least two of the journal's authors had studied the Sumbanese bird a century before independence.
Next, several other researchers arrived until 1944. Ernst Mayr was the last researcher in the pre-independence era. He noted there were 121 species of birds on Sumba.
After Indonesian independence, E.R Sutter went on an expedition to Sumba in 1949. However, until three decades later, no ornithologist was involved in bird research on Sumba.
It was only in 1979, Joh MacKinnon resumed bird surveys on Sumba, with the results in a list of species that had been systematically documented.
