Bird's Nest

Now these guys are really hard workers. They arrived to build on the opposite gable to the last lot blipped on Monday last, which, if the rest of them follow suit, probably means I'll be surrounded by a rampart of guano.
Interesting how they manage to stick in binding material with the mud and how there's even a small bit of decoration half-way down.
All they need now is the greatest jazz pianist ever to speed up the tempo of building the Bird's Nest!
