A small bird’s nest, intricately woven from fibre-optic cable and grass, has been discovered near the front line of the war in Ukraine, offering a stark illustration of how Russia’s war is reshaping the natural environment. The nest is one of several found in the region, with local birdlife repurposing discarded fibre-optic cables to construct their homes. These cables, which can stretch up to 20 kilometres, have been deployed by both Ukrainian and Russian forces to guide aerial attack drones, rendering them impervious to electronic jamming.
As a result, vast stretches of the 1,200-kilometre front line are now blanketed with the ultra-thin cables, which lie tangled in trees, scattered across fields, and draped over rooftops in Ukraine’s frontline regions. Researchers at Kyiv’s War Museum have been studying the nests, with senior researcher Yana Hrynko noting that they demonstrate the change in the nature of war. The use of fibre-optic cables is a key part of Ukraine’s efforts to counter Russia’s advantage in conventional equipment, with drones now dominating the battlefield.
Russia invaded Ukraine in February 2022 with tanks, armoured vehicles, and artillery, prompting Ukraine to pour resources into developing aerial drones. The impact of the fibre-optic cables on birds could be mixed, according to biologist Auke-Florian Hiemstra, who specialises in artificial nest materials. While the cables could cause harm by entangling birds, they could also benefit them by helping them make strong nests.
Hiemstra, who is based in the Dutch city of Leiden, will study one of the nests to determine which species built it and to document the impact of war on nature in Ukraine. The nests have been found in several frontline regions, including Donetsk, Kharkiv, and Zaporizhzhia, with Ukrainian servicemen posting pictures and videos online. One of the nests will remain in Kyiv as part of the War Museum’s war collection, while the other will be sent to the Netherlands for study and later returned.
The discovery of the nests has highlighted the ways in which war is reshaping the natural environment in Ukraine, with researchers working to understand the impact of fibre-optic cables on local birdlife.
