Acoustic gaze adjustments during active target selection in echolocating
Determining the mere presence of bats echolocating
is the most basic way to use a bat detector and can be done nearly everywhere in the U.
Nevertheless, the results convincingly demonstrate sufficiency--some sighted participants can achieve echolocating
precision approaching that of an experienced echolocator who is blind.
The sound emission pattern of the echolocating
bat, Eptesicus fuscus.
, they send bursts of clicks outward; lower frequencies to rough objects out, higher frequencies to fill in the details.
It is amazingly sophisticated and precise: An echolocating
bat can detect objects as small as a human hair; it can use riverbanks, vegetation and other terrain features as acoustic landmarks; and it can determine not only a target's speed and direction, but also its size and surface texture.
Barclay RMR and Brigham RE: Constraints on optimal foraging: a field test of prey discrimination by echolocating
The high-pitched sounds they emit when echolocating
are above the range of our human hearing.
Why do we find beating hearts, or echolocating
devices, or tit-for-tat patterns of behaviour, in this or that species or population?
At one point I am swimming with a mother and calf; the mother makes eye contact with me, and suddenly I feel it: the zap of the dolphin echolocating
me, almost like an electric shock.
A bat echolocating
in a bag is responding to a high clutter environment.
