A thought:

I propose that I, you, we march over to the local PetsMart, purchase a shitload of finches with a week's worth of wages then set them free.

Sure, they probably won't be able to fend off wild predators or effectively forage for food, BUT at least they'll be able to fly three consecutive feet and observe their environs without annoying metal bars breaking up the scenery. Death via being devoured by a bigger animal or "fuckin' wingin' it" is a google times hotter than passing out on last week's paper or eating one sunflower seed too many.

Besides, if the finches die within a day or two of their release because they can't find an upside down water bottle in nature we can just chalk it up to Darwinism and tell ourselves we had the misfortune of purchasing only the stupid finches.
