Are bat bridges better than bat caves?

Concrete bridges could make better roosts for Brazilian free-tailed bats than natural caves, according to research.

Scientists in Texas, US monitored the birth weight and growth of bat pups born under bridges over busy freeways and pups born in caves.

The team found that, rather than the relatively noisy man-made roosts being detrimental to the animals, pups born in bridges were larger and grew faster.

The findings are reported in the Journal of Zoology.
