If you've been spending a lot of time outside, you may have seen some new desert dwellers popping up.
It's baby rattler season and these little guys pack a dangerous punch.
It's a scary sound, but one that could save your life when you encounter a rattlesnake, however newborn rattlers can't tell you when they're nearby.
"They only have what we call is a pre-button here and so there's a single unit and the way they make sound.. is the rattles actually bump against each other when they're shaking.. there's two high points.. they actually hit where the baby just has a pre-button, so there's nothing to make any sound," said Russ Johnson of the Phoenix Herpetological Society.
Johnson says a mother rattler found this week and had eight babies at their facility. They try to make sound, it's just not possible yet.
"It'll shake its tail like crazy, but there's no sound, so people aren't going to get the warning. They're gonna have a snake around there," he said.
People often get struck when they're hiking and put their hand in a crevice where they don't see or hear the snake or sit on a log without spotting the slithering creature.
Whether you're working in the garden, walking your pet, or just playing in the backyard, these snakes can show up anywhere, but they want to avoid you as much as you want to avoid them. Keep in mind they're out more at night right now.
They'll be active very much, so at night this time of year, the prey isn't coming out until after dark, plus they can take the ambient in temp, but in the sunlight, this skin is like a solar panel, so it absorbs the heat, so if you leave them out in 110 degrees in sun.. they can boil and die," explained Johnson.
The mother and her eight babies will be released back into the wild.
