Structural engineer in action
Whether you’re a ‘bird person’ or not, this is stunning!.
Not to detract from the sheer magic of it, but in practical terms, how MANY trips would a bird
have to make with that tiny little quantity of mud/clay it could carry?
(and how far from the nest is the source?)
If you take the construction of a “circular bowl” in your stride as instinctive – how the heck
does the bird come up with the windbreak/entrance design that shields the eggs/chicks
from the elements – and at what point in fashioning the bowl do they start to construct it?
Even if you think you could build this? Try it without using your hands!
