What It’d Take to Build a Human-sized Robin’s Nest
Robins may make the work look easy, but in human terms it's one monumental project.
This story comes to you through a partnership between ±¬ÁϹ«Éç and BirdNote, a show that airs daily on public radio stations nationwide.

Wouldn't it be great to change places with a bird? To fly freely, to perch on the highest branch – even to share the joys of building a nest! Just like that, your wish is granted. You switch places with a robin. The flying part is fun, but there's work to do – there's a nest to build.
What would be the human-sized equivalent of a robin's nest? An average robin weighs less than three ounces. Let's say an average person weighs 170 pounds, or 1,000 times as much as a robin. A robin's nest, made of grass and mud, weighs about seven ounces, so yours will weigh 450 pounds. You'll need to collect about 350 strands of grass, each about four feet long. And don't forget the mud: 150 pounds of it. You have five days to complete the job.
Of course, being a robin, you'll have to carry all these materials in your beak. That's 300 mouthfuls of mud.
On second thought, maybe you'd rather switch places with a plover, and just rearrange pebbles on the ground to create a nest.
