At least, the Black Chinned Hummingbirds seem to, according to this article.

Man-made noise disrupts the growth of plants and trees
By Victoria Gill Science reporter, BBC Nature
The study is published in the Royal Society Proceedings B.

The team, led by Clinton Francis from the National Evolutionary Synthesis Center (NESCent) in North Carolina, tested the effects of industrial noise on wildlife in Rattlesnake Canyon Habitat Management Area (RCHMA), New Mexico.

This large forested area has a high density of natural gas wells, providing scientists with a unique setting that allowed them to study the effects of noise without some of the "confounding factors" often associated with noisy areas, such as roadways and artificial light.

In the first of two experiments, the team focused on birds, which, they explained, "are considered to be especially sensitive to noise pollution owing to their reliance on acoustic communication".

They placed patches of artificial hummingbird-pollinated flowers in noisy and quiet areas.

These convincing flower copies contained tubes of nectar, enabling the researchers to track exactly how much sugary fluid was consumed by visiting hummingbirds.

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. "
