Call shape
To view call graphics click on the camera icon on the right. You can then move through all images by using the left or right arrow keys. A left mouse click returns to the fact sheet.
Typical North American Vespertilionid pulses with FM reversed J broadband pulses of short duration. However, call shapes vary depending on what the bat is doing when recorded. Pulses range from steep FM broad-band pulses of short duration to longer duration pulses with a pronounced rounding of the lower part of the pulse. Several examples are provided.
