(BBC) - Industrial din, the scientists discovered, actually increased the activity of the birds. One species in particular - the black-chinned hummingbird (Archilochus alexandri) - made five times more visits to noisy sites than quiet ones.
So that's why Big Bird applied to work in a nearby steel mill.
Dr Francis explained that these hummingbirds might prefer noisy sites because another bird species that prey on their nestlings, such as western scrub jays, tend to avoid them. (story)
The birds also prefer the sites because they are huge Skrillex fans.
