4Elephant Puppet Meets A Bat (chiroptophobia Warning)🦇
Bat calls are very variable, in particular with the nature of the bat's surroundings. In unusual locations And You Could Hear It Around 0:30
cicumstances, the calls may differ significantly from the typical pattern described for the species.
In a specific environment (such as woodland), the calls of many species will sound quite similar as the bats
adjust their calls to suit the structure of their surroundings. The environment must always be kept in mind.
Accurate identification of species from echolocation calls is not always possible. Additional information such as the appearance of the bat, the pattern of flight and the structure of the environment will sometimes help.
The key does not cover social calls.
The key covers only the 16 (or 17) resident British species. If vagrant European bats are encountered, the key
will not be successful even in approximate identification and may give very misleading results. It is essential that the bat detector is used actively, by adjusting the tuning until the frequency range of the call, the frequency at which the call sounds loudest, the sound quality at different frequencies and the apparent drop in volume at different frequency settings have all been noted. The repetition rate (rapid, medium or slow), the regularity or irregularity of the rhythm of calls, and any apparent volume fluctuations should also be considered. Taking account of all these factors requires considerable practice with the detector before reliable identifications can be attempted. Bats in Norfolk
