It is being reported by a local mom that a Timber Rattlesnake was found in the area of Tattersall’s Machine on Route 140 in Upton. These types of snakes are venomous! It appears to be a baby. If this is not an abandoned pet, it’s Mom is not far away.
Here is a link to a Timber Rattlesnake information page.

Yikes!!
Not good news for most of us who are snake phobic!
Be careful out there, kids.
Is the picture posted the actual Upton snake or a stock photo?
No doubt Upon once long ago had a rattlesnake population, but unless a clear picture of the actual snake is availalbe skepticism is warrented. It could be a case of mistaken identity. The eastern hognose snake occurs in Upton. It has markings that resemble a rattlesnake but has no rattle and is harmless.
This is not the image of the snake in Upton but a stock photo. I think they are having it verified. I will update. Thanks Mike!
