乌克兰的鸟用战场上的光纤筑巢，有的还用防鸟刺造窝，鸟类工业革命来了？

Core Viewpoint - Birds have been observed using fiber optic materials to construct nests, marking them as the third known species on Earth to utilize such technology, following humans and chickens [1] Group 1: Fiber Optic Usage by Birds - The Ukrainian National Guard's 12th Special Forces Brigade shared an image of a bird's nest made primarily from FPV drone fiber optics, showcasing a unique and cyberpunk-like scenario [3] - Previous instances of birds, such as magpies and crows, have been documented using anti-bird spikes to create "armored nurseries," indicating a trend of birds incorporating unconventional materials into their nesting practices [5][6] Group 2: Impact of FPV Drones in Warfare - FPV drones, capable of real-time transmission and maneuverability, have been modified in the Ukraine conflict to penetrate armor and attack tanks, with Ukrainian forces reportedly destroying 80%-90% of Russian armored vehicles using these drones [10] - The use of fiber optics in FPV drones has become crucial as it mitigates the vulnerability to electronic interference, allowing for uninterrupted signal transmission even in complex electronic warfare environments [12] Group 3: Environmental Concerns - The discarded fiber optics from FPV drones create extensive artificial "webs" across Ukrainian landscapes, posing risks to agriculture and wildlife, including endangered species [14] - Research indicates that these fiber optics are difficult to biodegrade, potentially remaining in the environment for over 600 years, raising concerns about long-term ecological impacts [17] Group 4: Bird Nesting Behavior - Birds exhibit flexibility in nesting material selection, often opting for readily available, sturdy, and camouflaged materials, which explains their choice of fiber optics for nest construction [20][21] - The use of fiber optics may lead to increased mortality rates among chicks due to the material's potential to entrap or injure them, raising questions about the long-term viability of such nesting practices [24][25] Group 5: Adaptive Behavior of Birds - If the use of artificial materials like fiber optics results in higher chick mortality, birds are likely to abandon such nesting sites in future breeding seasons, demonstrating their ability to learn from experience [27]
