Rattlesnakes

Venomous rattlesnakes are very common in the Los Vaqueros Watershed.

 A rattlesnake is distinguished by a triangular-shaped head that is noticeably larger than its neck, a dull body and a blunt tail with 1 or more rattles. It is very likely that you would hear a rattler before you see it.

When a rattlesnake feels threatened, it will shake the rattles on its tail as a warning before it strikes. It is important to listen for this fast rattling sound (almost a hissing sound) when you are hiking or engaging in other activities in the watershed.

  • Stop what you are doing and remain still.
