Feathers at work
Small structures with more than one job.
Before you jump in
A bird's feathers can look like a smooth coat until a breeze lifts one edge and reveals the layers underneath. Some lie flat, some look fluffy, and others form the long outline of a wing or tail. Those differences are useful clues. This quiz asks how the structure of a feather relates to the work it performs.
You will begin with familiar functions before examining the tiny branches that make a feather more elaborate than it first appears. The later questions connect everyday preening with maintenance and distinguish care of an existing feather from growing a replacement. No bird identification test or specialist vocabulary list is required in advance; the explanations build the picture as you go. Imagine looking first at a whole bird, then at one feather, then much closer still. Each change of scale reveals another part of the same design.
What you’ll explore
- Insulation and flight
- Shafts, barbs, and barbules
