Fig. 6. (A) Call parameters of a wild Eptesicus fuscus foraging in an open
area as it attacks a flying insect [duration and instantaneous pulse period
data computed from original data of Surlykke and Moss
(Surlykke and Moss, 2000) with
their definitions of echolocation phase]. (B) Expansion of the approach and
terminal phases shown in A; points are marked where C. tenera's
phonoresponse begins (B) and/or where it is most pronounced (*), as
extrapolated from stimulus pulse periods described in the following studies: 1
(Fullard, 1984); 2
(Fullard et al., 1994); 3
(Ratcliffe and Fullard, 2005);
4 (Barber and Conner, 2006).
For both graphs, duty cycles were computed from the original data.
