I have lived in MA for years and I have never seen a rattlesnake. Why not?

While rattlesnakes are native to Massachusetts, most people have never seen a rattlesnake here. Timber rattlesnakes were once widespread across western, central, and northeastern Massachusetts, but their lower reproductive rates and longer maturation period have made them highly vulnerable to many threats, leading their populations to be small and declining. Today, their statewide population is only in the hundreds and scattered over a small handful of areas, making the chance of seeing one very low. They require a specific habitat which includes mountainous terrains with steep ledges or rockslides close to forested areas with a large population of rodents. Sightings of timber rattlesnakes are also very low because they hibernate for six months of the year. They are usually active from mid-April to mid-October and rarely move or eat the first several weeks after emerging from hibernation.   

We have rattlesnakes in MA?! I thought there were no venomous snakes here.

Only two of the fourteen types of snakes in Massachusetts are venomous: the timber rattlesnake and the copperhead. Both live in only a few areas of the state, and both are listed as endangered under the MA Endangered Species Act. 

Timber rattlesnakes use venom to immobilize their prey, such as mice, chipmunks, squirrels, rabbits, and birds. Venom is costly for them to produce and they will only use it when needed. Both rattlesnakes and copperheads avoid people and pose no serious threat when left alone.

Why do rattlesnakes rattle their tails?

When you hear a rattlesnake's rattle, it's time to skedaddle! Rattlesnakes use their rattle to warn you that they are feeling threatened and you should back away. Overall, rattlesnakes try to go unnoticed. They are sneaking up on their prey and don't want to gather attention of potential predators. They use their camouflage and low position to the ground to stay under the radar. If a rattlesnake continues to feel agitated after warning you with its rattle, they may decide to strike. 

What should I do if I see a rattlesnake? How can I avoid them?

If you see a rattlesnake, the best thing to do is to maintain a safe, respectful distance. Do not handle or otherwise disturb them and continue on your way.  If you aren't sure what species of snake you are looking at, treat it as though it is venomous and give it plenty of space. To avoid an encounter, make sure to stay on trails, and keep pets leashed. Because these snakes are rarely seen, please let us know if you happen to see one! Send an email with any photos (taken from a distance) and location to natural.heritage@mass.gov. 

How big are rattlesnakes? What do they look like?

Adult timber rattlesnakes range from 35-60 inches long. They have a broad, triangular head and variable color patterns. Some are almost jet black. Others appear sulfur-yellow with black, brown, or rust-colored blotches, which are separated by cross bands on the back and sides. They can sometimes be confused for Northern watersnakes and milksnakes.  

Why are rattlesnakes endangered? What is being done to conserve them?

Threats to timber rattlesnakes include habitat loss and fragmentation, road mortality, targeted and incidental killing, collection, harassment, and fungal disease. It is illegal for anyone to kill, collect, possess, import, or move rattlesnakes in Massachusetts.?MassWildlife is actively working to conserve rattlesnakes in Massachusetts through land protection, monitoring, habitat management, road mortality reduction, and public education.

Pittsfield School Officials Refer PHS Report to State Records Supervisor

Mayor Peter Marchetti asks that the committee not discuss the report in executive session, as he felt it did not fall under OML exemptions.

PITTSFIELD, Mass. — The state now controls what can and can't be released on the Pittsfield High School investigation.

On Wednesday, the School Committee voted to refer the investigative report to Manza Arthur, supervisor of records with the secretary of state's office, and ask her to return a proper redacted report to release to the public.

The Pittsfield Public Schools have been ordered to release non-exempt parts of Bulkley Richardson & Gelinas' investigation into alleged staff wrongdoing by May 8 after community advocate Ciara Batory filed a public records request.

"Although people will say this isn't true, it is not the case that the School Committee is trying to stop anybody from knowing whether it's safe to have their kids go to school, but there is a concern about just how far that assurance has to go," Chair William Cameron said during Wednesday's meeting.

"And we'd like to be in well, in fact, we will act in accordance with the law as it's ultimately determined to be, but I don't believe that the letter we got is a satisfactory basis for our proceeding."

The School Department initially denied Batory's public records request on April 1, and following an appeal to the secretary of the commonwealth's Public Records Division, Arthur ruled on April 24 that the district failed to justify withholding the report in full and ordered that any non-exempt portions of the report be provided.

"That is not a suggestion. That is not an option. You are legally required to release the report. Yet the families affected and this entire community are still being denied the truth they deserve. Let me be very clear: withholding that report, after a direct order from the state, is not just unethical, it is unlawful. Every day you delay, every excuse you give, further destroys the public's trust in this school system," Batory said during open microphone.

"It does something else: it discredits the many teachers and staff who work hard every day to support and protect their students who care deeply, but are too afraid to speak out for fear of retaliation. Your silence sends a message that doing the right thing in this district comes at a cost. That protecting the system is more important than protecting the people in it."
