New research is reshaping the image of the dodo, the extinct bird that has long been treated as a symbol of stupidity. Based on skull scans, researchers say dodos were likely no less intelligent than the birds they are related to, challenging a reputation built more on myth and later storytelling than on evidence.

The study suggests the dodo’s brain was in line with what scientists would expect for its surviving relatives. That means the bird may have been better adapted to its environment than its historical image implies. Instead of being unusually slow-witted, the dodo now appears to have been a typical island bird with traits suited to life on Mauritius.

The scans also point to another possible insight into dodo behavior: the species may have been most active at dusk and dawn. If that interpretation is correct, it would offer a more detailed picture of how the bird moved through its habitat before disappearing more than 300 years ago.

Dodos were wiped out within decades of humans arriving on Mauritius, and much of what people think they know about the species has been shaped by limited records and popular culture. This new work adds to a growing effort to understand the bird through science rather than stereotype, suggesting the dodo was not the foolish creature history made it out to be.
