![]() Snakes are looking to hibernate for the winter and will often find crawl spaces to be safe, warm and damp. What temperature do black snakes hibernate?Īt what temperature do snakes become inactive? Generally, rattlesnakes emerge from hibernation in March or April, or when the average daytime temperatures reach and remain about 60 degrees Fahrenheit and higher. For the majority of the time they are sleeping through the winter as being cold-blooded they need the warmer weather to eat and metabolise,” Maria said. They will however come out on a sunny day to sunbake and that is why it’s not true hibernation. “A snake will find a burrow or a log and sleep. Because snakes are cold-blooded, they can’t regulate their body temperatures like warm-blooded animals can. Instead, snakes go into a state known as brumation where snakes become less active and their metabolism slows down tremendously. Unlike many warm-blooded animals, snakes don’t actually hibernate in the winter. 2 What temperature do black snakes hibernate?.1 Do black snakes hibernate in the winter?.Research published in the Herpetological Journal has warned that at current rates of decline, the adder could be restricted to just a few sites in the UK within 10-20 years. The adder used to be widespread across Britain but has declined markedly in recent years, particularly in middle England. As a result the TV presenter Chris Packham, who lives in the area, has called for dogs to be banned from nature reserves in the People’s Manifesto for Wildlife he launched last year. However, dogs off leads will often attack adders and there have already been reports this year of adders biting dogs in the New Forest. ![]() Although they are venomous, no one has died from an adder bite in Britain in more than 40 years and conservationists have in recent years tried to tackle the reptiles’ “image problem”.

Being active in winter brings them into greater contact with humans and dogs, leading to increased disturbance at their hibernation sites at a time when they are particularly vulnerable because they are sluggish and bask in the open. The recent unprecedented temperatures have resulted in adders emerging from hibernation up to a month early. “Adders have already been recorded as being seen throughout the year in a national park in the Netherlands, so I have no doubt they are now active throughout the year in Britain as well.” “I’ve seen adders in every month of the year except December, but have had reliable reports of them being active then in Wales,” he said. Nigel Hand, a trustee of Amphibian and Reptile Groups of the UK and one of the country’s leading adder experts, confirmed the trend. While the adder is well adapted to cold weather, occurring further north in the world than any other snake species, this is new behaviour and experts warn it is a clear sign of the impact climate change is having on wildlife. A shorter hibernation period and becoming more active in winter is likely to accelerate their demise, as snakes will be much more susceptible to any cold weather that follows a warm spell.įollowing the record warm temperatures in February, adders have been seen in every calendar month. They are declining as a result of increasing habitat loss, persecution, predation, disturbance and inbreeding. ![]()
