Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of 802.11 Wireless Networks: The Definitive Guide, Second Edition, is a horseshoe bat (Rhinolophus hipposideros). This rare and globally endangered species is the smallest of the European horseshoe bats; they typically weigh only 4 to 10 grams and have a wingspan of 19 to 25 centimeters. Horseshoe bats get their name from the horseshoe-shaped, leaflike plate of skin around their noses. This nose-leaf helps modify and direct the ultrasonic sounds they emit through their nostrils (a method of sensory perception known as echolocation) to orient themselves to their surroundings, detect obstacles, communicate with each other, and find food. Bats' echolocation systems are so accurate that they can detect insects the size of gnats and objects as fine as a human hair.

Lesser horseshoe bats are found in a variety of habitats, ranging from the British Isles to the Arabian Peninsula and Central Asia, and from Morocco to Sudan. The lesser horseshoe bat was originally a cave-roosting bat, but many summer maternity colonies now occupy the roofs of old rural houses and farm buildings. These bats also sometimes roost in hedgerows and hollow trees. Maternity colonies of 30 to 70 are normal, but roosting mothers have been known to form colonies of as many as 200 bats. Lesser horseshoe bats hibernate, sometimes in large groups, from October until late April or early May. Their winter roosts are usually underground, in caves or tunnels. They hang by their feet with their wings wrapped around their bodies, often in open and exposed positions but rarely in large clusters.
