We are halfway through 2026, and while we aren’t flying across gleaming neon cityscapes in jet-powered cars, birds have been discovered feathering their nests with optical fiber. It definitely isn’t the tech utopia we dreamed about, but the birds might have been colder without this detritus of war. Moreover, our feathered friends are tidying up the miles of fiber waste precipitated by drone warfare, at least a little bit, while making use of what is likely an excellent thermal insulator.

Example photos of these optical fiber nests were shared on Twitter/X by a Ukrainian civil society leader and anti-corruption advocate, Olena Tregub. She called the carefully woven avian construction an “apocalyptic bird's nest” and credited Oleg Malchenko as the photographer. We can’t say how widespread such nests are, they are the first we’ve seen, but birds can be quite enterprising when nest building and choosing the best materials.
Some background to the finding was given by Tregrub. “A Russian glide bomb knocks down a tree in Donbas,” said the former Ukrainian government official. “From the shattered branches rolls out a tiny bird’s nest. Made of drone fiber-optic cable.”
Imagery showing acres of fields strewn with wisps of optical fiber are one of the sad signatures of the current Russia-Ukraine war. To make no-fuss jam-proof drones both sides have been using optical fiber tethered drones to target their foes.
In October last year we reported on a Ukrainian invention utilizing rotating barbed wire barriers to snag, rip, and disable any fibers left in the wake of drones flying over them. Another example of ingenuity in this David vs. Goliath conflict.
In December, we reported on the tethered drone range of Russian FPVs being significantly boosted by a grey-zone Chinese partnership. This tech collaboration between communist nations resulted in the production of fiber optic spools delivering as much as 65km (~40.4 miles) of tethered range. That was an advance of previously seen Ukrainian tethered drones reaching 42km (~26 miles).
