What defensive action precedes striking if a Black-tailed Rattlesnake feels cornered?

Answer

Issuing the characteristic warning sound from its rattle

When physically cornered, trapped against a rock, or suddenly stepped upon, the Black-tailed Rattlesnake will transition from passive defense to active self-protection via a strike. However, prior to deploying its venomous bite, it typically utilizes its namesake feature to signal danger. This warning involves vibrating the segments of its rattle to produce a distinct warning sound. It is important to note that relying solely on hearing this sound is risky, as accounts indicate that the snake may not always deploy the rattle, especially if the startle is sudden.
