walk through underbrush in the Florida woods, and to listen for the sound of rattles. If a

person approaches a Diamondback that is in the open, it will usually coil and begin rattling

when the intruder is about 15 to 20 feet away. If it is well concealed, it might not rattle at all,

or it might wait until the person is dangerously close. A Diamondback can also lose some or

all of its rattles, so even though it is vibrating its tail, its warning might not be heard.
