"Seems to only apply migratory birds, not the ones that stick around all year like pigeons and whatever kind the cat catches and leaves feathers all over the porch. \n  \nSo it would seem that a non-migratory bird nest could be made into a cache or used to conceal a cache? Seems it's time to crawl up into the rafters in the barn for a ready-made cache that otherwise would be a fire hazard :-) \n"
