Simple Syllabic Calls Accompany Discrete Behavior Patterns in Captive Pteronotus parnellii: An Illustration of the Motivation-Structure Hypothesis
Figure 2
(a) A group of approximately 65 mustached bats roosting within an upside-down clay pot mounted in the ceiling of the flight room. (b) The range of roosting positions for mustached bats, over a two-week period, by sex. The bat’s head (top right) is drawn to scale to indicate that the farthest extent of roosting location is typically the size of the body width of an individual. Symbols (solid diamonds for males and unfilled circles for females) are located at the mean (center point) location of an individual within the roost, and the bars indicate the range of individual-specific roosting locations.
