In the Museum of Natural History at Soleure, in Switzerland, there is
said to be a bird's nest made entirely of steel. There are a number of
clockmaking shops at Soleure, and in the yards of these shops there
are often found lying disused or broken springs of clocks. One day a
clock-maker noticed in a tree in his yard a bird's nest of peculiar
appearance. Examining it he found that a pair of wag-tails had built
a nest entirely of clock springs. It was more than four inches across
and perfectly comfortable for the birds. After the feathered architects
had reared their brood, the nest was taken to the museum, where it is
preserved as a striking illustration of the skill of birds in turning
their surroundings to advantage in building their nests.
