Structural Construction

i found this

nest

of a

Barn Swallow BARS* (Hirundo rustica)

Interesting

 

Often this species will utilize a ledge or somewhat porous or irregular surface on which to build its nest

Here the metal siding would not have provided good adhesion for the mud construction techniques

i didn't notice evidence of "trial & error" so the 'architect-builders' of this nest would seem to have been ingenious to have chosen this material -meshing as a home site.

 

i am curious to monitor over the winter and see how it stands up -- and if it is reused next year.

Imagine how many trips with mouthfuls of mud and straw to have built this!

i wonder how long it took....?
