Did you know that bats breed better on bridges than in caves?

It seems counterproductive what bats do to live on bridges under noisy highways than in silent natural caves. Why do they do it?


According to the study’s lead researcher, Louise Allen, the causes of earlier and higher growth could be as simple as higher heat and proximity to food.

Jumpers are often closer to foraging sites and are warmer. So they can spend less time and effort on thermal regulation and more of that time on fat deposits and bone growth.

Contrary to what they expected, they found that man-made and relatively noisy places were more beneficial, as the young born on the bridges were bigger and grew faster.

Allen took advantage of the results of the research, carried out with bats captured in Texas, to indicate that the bridges can serve to expand the distribution of bats and take them to northern areas, escaping climate change.
