"Clever Crows: Turning Anti-Bird Spikes into Nests"

Carrion crows and Eurasian magpies have been observed using anti-bird spikes as materials for their nests, strategically positioning them to potentially defend against predatory birds. These metal pins, typically used to deter birds, serve to secure twigs and support the nest structure. This behavior highlights the adaptability of birds in utilizing man-made materials for nest construction, as seen in previous instances such as the Australian 'Parkdale Pigeon' nesting on top of anti-bird spikes.
