There is an oddity that I noticed that there are many birds that build nests not in the trees.
Many corners of buildings or places other than trees are used as their residence. I think they have adapted to the conditions of less and less trees. Unlike at my place, they can always be found in the trees.
Mostly here the nest are in trees as there are plenty of trees here, the Osprey nests are built so they have a safe spot out on the water and away from people I think
