Dinosaurs at your bird feeder. I’m Bob Hirshon and this is Science Update.
Birds are descended from dinosaurs, a fact that led Science Update listener Russell Ginns of Bethesda, Maryland to call our 1-800-WHY-ISIT line as he watched birds squabbling at his bird feeder.
RUSSELL GINNS (Bethesda, MD):
Is it possible I’m watching dinosaur behavior exhibited?
Paleontologist Joe Sertich at the Denver Museum of Nature and Science says it’s plausible.
JOE SERTICH (Denver Museum of Nature and Science):
The behavior of birds in your backyard probably is very similar to at least the small theropod or meat-eating dinosaurs.
For instance, he says theropod brain structure indicates they moved like birds.
So the way they kind of hop around and kind of jerk and move their head from side to side, that’s probably something you’d see in a small meat-eating dinosaur as well.
