Wood engraving 1884.Universal History Archive—Getty Images by [Sarah Begley](https://time.com/author/sarah-begley/) ## Sarah Begley Feb 24, 2016 3:58 PM UTC Calling people dodo-heads when you think they’re being dumb may not be as accurate an insult as we thought, according to new research. The [_Zoological Journal of the Linnean Society_](http://onlinelibrary.wiley.com/doi/10.1111/zoj.12388/abstract)found that dodos, birds that went extinct centuries ago, actually had a similar brain-to-body size ratio as pigeons, considered quite intelligent birds for their ability to be trained. Imaging also revealed that the extinct species would have had larger than usual olfactory bulbs, giving them a stronger sense of smell than other birds. Dodos were long thought to be stupid because they were so comfortable around humans that they were easily hunted on their native island of Mauritius. Their trusting nature and the introduction of invasive species wiped them out a century after they were discovered.  The skull that scientists examined is “not impressively large or impressively small—it’s exactly the size you would predict it to be for its body size,” the lead author said, according to a [press release](http://www.eurekalert.org/pub%5Freleases/2016-02/amon-dmh022316.php). “So if you take brain size as a proxy for intelligence, dodos probably had a similar intelligence level to pigeons. Of course, there’s more to intelligence than just overall brain size, but this gives us a basic measure.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4235496/dodos-smart-brain-size/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4235496/dodos-smart-brain-size/"},"headline":"Dodos May Have Been Smarter Than We Thought","datePublished":"2016-02-24T15:58:18.000Z","dateModified":"2026-05-11T05:00:21.520Z","description":"The brain-to-body size ratio was found to be on par with pigeons","url":"https://time.com/4235496/dodos-smart-brain-size/","keywords":["animals"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0484f061669c59c2/69887eeb428a9e7ff3cd1845/dodo-bird.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Sarah Begley","jobTitle":null,"url":"https://time.com/author/sarah-begley/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0484f061669c59c2/69887eeb428a9e7ff3cd1845/dodo-bird.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Dodo - Raphus cucullatus, formerly Didus ineptus - extinct flightless bird from Madagascar.
