Emus might not be the 'world's dumbest bird' after all

The insult "bird brain" should probably be retired. Eurasian jays can pass the marshmallow test, some species have "culture", and even extinct avians like the dodo were probably smarter than we previously thought. Large birds called palaeognaths–the closest living relatives of dinosaurs–are considered more simple. However, a small study found that some large birds are also capable of innovation. They can solve a physical task in order to access food, according to a study published February 20 in the journal Scientific Reports.
