The war in Ukraine has now gone on for so long that, birds in the Donbas region have adapted and are using strains of Drone control fiber optic cables to build their nests.

A post from Ukraine claims that this half-finished nest was found after a tree fell during a Russian glide bomb bombing.

Let us make it our goal, that our children will inherit a world in which birds once again build nests out of twigs and stalks.

@randahl looks like fishing string tbh. Any fiber line I've seen for data has outer insulation to keep outside light out and inside light in.
@randahl @terminhell I'd say that most important thing is range and insulation would be heavy...
