rooftops
Storks are the national bird of Belarus. Their nests are high off the ground, in trees or rooftops, or pylons. They evolve over time as the pair return year after year and expand, alter and redecorate. Some nests have grown to 2 metres wide and could be decades old (and are, eventually, passed on to other pairs)
Some people's nests have thatched roofs that require repairs every 10-25 years or so. It can be eyewateringly expensive, but is environmentally friendly and the materials are sustainable. And is so pretty. With the wildfires we are experiencing, it is a good thing that it is not a common practice here.
