I depicted the cloudy nest during the construction stage, in general, their nests are much bigger with a small entrance hole at the top (just like the separated thumb of the mitten). They use plant fibre to make their nests, lined with soft animal fur, plant down, and spiderweb to ensure the comfort and isolation. The nests are carefully woven around the branches and usually hung right over the water.
So the first prize goes to the Penduline tits and their fabulous nests! I would give them my heart too.
