Revisions log for Answer #1504

Birds don't usually defecate in their nests, nobody defecates in their dormitories. I mean, the problem is overrated. It should also be a problem for kids, how exactly!!!? Do they inhale it every day? The swallows are almost gone because they can't find nesting places under the eaves. We have an old house and two sparrows nest in a similar position, year after year. It's nice to hear the chirping in the spring – and neither house or babies show any signs of dying from it. But with the new building, I can understand that. Still, please wait until breeding season!
