After meeting Australian anthropologist Norman Tindale, of the South Australian Museum and University of Adelaide, in 1936 when Tindale visited the US, Birdsell made his first field study in Australia in 1938. In May 1938, the two men and their wives visited CummeragunjaAboriginal reserve in New South Wales, as part of an extensive anthropological survey of Aboriginal reserves and missions across Australia. Tindale would study the genealogies, while Birdsell undertook the measuring, and with government support the pair travelled across south-east Australia, parts of Queensland, Western Australia, and Tasmania. and returned periodically to study microevolutionary processes. Together with Tindale, in field-work over 1938–39 in the Cairnsrainforest, he concluded that the Indigenous "pygmy" peoples there, which they collectively called Barrineans, belonged to a group that were genetically distinct from the majority of Australian Aboriginal peoples, perhaps related to the Aboriginal Tasmanians.

Later career
He completed his doctoral degree at Harvard in 1941. After teaching briefly at the State College of Washington, he served as an Army Air Corps officer in World War II. He taught anthropology at UCLA from 1948 until his retirement in 1974, continuing his research, and writing many articles and a widely used textbook on human evolution. His lifework was summarised in a monograph published in 1993 by Oxford University Press. He was awarded a Guggenheim Fellowship in 1946, and several of his field seasons in the Australia were financed by the Carnegie Corporation. He had a productive 50-year collaboration with Tindale. He also collaborated with U.S. physical anthropologist Earnest Hooton, who was professor at Harvard when he was a graduate student.
Early scholars had tended to view the peopling of Australia as the result of three separate waves of immigration, with distinct human types. Birtdsell took a biological approach and did extensive work on anthropometrics to buttress his conjecture. This trihybrid model was resurrected and espoused by Birdsell, and became a standard part of Australian history down from the 1940s. It was adopted by the then doyen of Australian historians, Manning Clark in his 6 volume history of the country. In a recent polemic, Keith Windschuttle and Tom Gittin observed that the model had dropped from view, and attributed political motives to its disappearance off the popular and academic radar. McNiven and Russell argue that the trihybrid theory was discarded as the natural outcome of advances in archaeological work on the populating of the Australian continent, and that Birdwell's theory's initial popularity was due to the old colonial mentality informing opinion, which saw in the successive wave theory support for the dispossession of Aboriginal people and to undermine native title claims. In his seminal paper of 1977, "The recalibration of a paradigm for the first peopling of Greater Australia", he examined the standard models for the origins of Aboriginal Australians regarding how human migration from Southeast Asia could cross the Sahul barrier. Birdsell theorized a distinctive model challenging the accepted view, outlining three variants for a northerly model positing a route through Sulawesi, and two for a conduit to the southern continent via Timor.
