Description Slow-speed recording of a Brazilian Free-tailed Bat feeding echolocation
Note Feeding buzz. When a bat detects a flying insect that it might want to eat, the search phase calls change to a feeding buzz. The calls become somewhat higher pitch, but most notably, they are produced so rapidly that the individual calls merge into what sounds like a buzz. Source: This recording was made by a high frequency bat detector. The pitch (frequency) for this recording has been lowered by a factor of 16 so the calls fall within the range of human hearing.
