Data from: Unpredictable aggressive defense of the venomous snake, Crotalus ravus, towards predators and humans

This dataset shows data on the behavioral response of the Mexican pigmy
rattlesnake Crotalus ravus to the approach of simulated predators (an
overflying bird, an attacking bird, and a fox) and a human and its
behavior towards a prey (mouse). All observed behaviors are included and
consisted of escape, rattle, bite, freezing the body, lateral compression
of the body, elevating the head, and hiding the head near or below its
body. 21 snakes were tried in all tests. For each trial, the data shows
behaviors presented, their frequency, the chronological order in which
behaviors were displayed, and the distance from the predator or prey
(i.e., the approach distance). When the snake escaped the flight distance
is given. In cases of the behavioral responses body compression and rattle
duration is also given. The first response is given with the reaction
distance, also the first essential behavior shown is given. Essential
behaviors are escape, rattle or bite, so called because these important
behaviors may avoid or result in an ophidian accident.
