- Phyllostomid bats
Neotropical Leaf-nosed bats (Phyllostomidae) show a huge range of feeding habits and can be found in many different habitats. Their sensory system is adapted to integrate different senses for orientation, navigation and target localization such as scent, vison and hearing. Besides listening passively to prey generated sound they use echolocation to assess their environment. Their huge diversity however is not reflected in the echolocation calls. These are usually multiharmonic, frequency modulated, short (< 2ms), and have a large band width. Only few species’ echolocation calls deviate from this general pattern and I want understand how this reflects ecological adaptations. Also, I am interested how other senses can complement for echolocation.
