Although they have no feathers, many bats have acquired powers of flight that rival those of birds. A high flier like the common noctule bat has long, narrow wings that are ideal for wheeling and gliding in the open sky above the treetops where it catches its prey (mainly cockchafers, moths and other large insects). Smaller insect eaters hunt low down between trees and buildings, and have shorter, broader wings that allow them to manoeuvre easily in confined spaces. |
