“The wind-up birds are a flock of mechanical woodpeckers, having found their first home in a forest in Lillehammer, Norway as part of the UT-21 project.
How will nature treat them, with hostillity or acceptance? How will the wind-up birds adapt to heat/cold wet/dry conditions? Will small insects creep inside the circuitry creating possible short circuits, beetles eat the wood, squirrels use the wood slit as nut storage (or the roof as a slide?), birds use it as a shelter, etc.? Will they be treated as foreign objects or accepted into the local eco-system?
How do real woodpeckers react? Are they threatened, attracted, or not bothered? Will they use the roof as a pecking drum? Initial tests indicate an attraction: it took 15 minutes for a real woodpecker to join a wind-up bird on the same tree.”
