We have seen what happens when the birds are turned off.
Children keep their heads to the stone. No mouths come formally, covered in shit and cursing while scraping tongue with a silken cravat. No fairy to ever find a feather, twist it about while spiraling down and down on abandoned wings. I pay a boy now, not a crow, to bring me jewelry at dawn.
And the off switch had been there the whole time, like a town hall clock, but no one cared. Birds seemed like such a delightful thing (when they weren’t stuck in their death songs in your car’s grill.) They could be peripheral. A man could walk in the city and take no note of the birds all day, yammering to himself and flicking spit on the ground where the little birds danced and fought over detritus. Human spit, at some velocities, with wrap around eyes, may often and sometimes look like a disappointing worm.
Do you suppose the birds, where ever they were taken when the switch was finally pulled, ever think back on human spit with longing? Perhaps no bird ever tasted human twice. Ostriches, perhaps, in their quarterly rages took an ear here and there. Undocumented ears, now digested or buried in head holes, growing new and illegal humans to take the birds’ place in the sky.
