Vampire bats usually bite then lap up the blood on sleepy out grazing animals.
Ideally a vampire would not kill his food source but use it lightly for he/she would be assured of a continuing food source. If however a vampire wishes to create a new vampire then he would 'kill' his victim slowly assuring that the vampire contagin was in effect when the person died.
Bats use their sense of hearing to find food. They use echolocation similar to dolphins.
Through General knowledge, (I may not be correct) Vampire bats locate their food through supersonic waves they emit, the waves bounce from surfaces and much like the process we use to calculate how far away lightning is by counting in between flashes, the vampire bat locates it's prey.
They use there sence of smell and some bats use echolocation x
The fruit bat!
to find where blood is close to their victims skins
Bats use ECHOLOCATION'S TO NAVIGATION around barriers and to find insect to eat.
they use sound to navigate and FIND there food but not to actually get the food, theyll use there eyes for grabbing berries or animals
Yes, bats can use echolocation to find their food. They emit a high squeal and listen for the echo to find things in the dark.
do your homework yourself, use a thesaurus
Vampire bats use echolocation, but they can hear what we hear, and more. They have an acute sense of hearing in the high frequency range, detecting up to 113 kHz, compared to the average human's hearing which can comfortably detect up to about 17 kHz. Vampire bats use this high frequency, or ultrasonic, hearing to analyse echolocation, meaning the echoes of their biosonar calls. Vampire bats are different from other bats in that they also have exceptional low frequency hearing. For audio clips on what vampire bats can hear compared to humans and to other bats, see the related link below.
Generally they fly, occasionally they glide. They also use Echo-Location like all other bats.
