Measuring from 3 to 4 feet or more than in length, the timber rattlesnake is the largest venomous snake in New York. The tape length in New York is 60 inches. Despite their size, cryptic patterns and coloration allow them to easily conceal themselves by blending in with their surround.

The coloration of the species is incredibly variable just can be cleaved down into ii distinct color phases, light and nighttime. This designation is determined by the colour of the head.

This species has coloration that varies considerably between individuals and populations. Dark crossbands or chevrons overlay the base color and can range from yellows and shades of brownish to blackness. Timber rattlesnakes besides have a dorsal strip, which is often anecdote but can vary between tan, light orange, and xanthous. In dark individuals, this is oftentimes broken up by the chevrons. Snakes will take the same pattern and coloration for the duration of their lives. The design generally fades into blackness towards the tail, which results in the antiquated name "old velvet tail".

A member of the pit-viper family unit, the timber rattlesnake has paired temperature-sensitive openings, or loreal pits situated below and in betwixt the eye and nostril. The purpose of this sensory organ is to detect prey and potential predators. Timber rattlesnake have a broad, triangular head with many small scales on the crown, bordered by a few big scales over the eyes, the loreal pit and rostrum (nose). Scales accept a middle ridge or keel, giving this rattlesnake a somewhat crude-skinned appearance.

The key characteristic distinctive to rattlesnakes-providing their namesake-is the rattle, which is made of loosely attached segments made of keratin. A new segment is added to the base of the rattle each fourth dimension the serpent sheds. When vibrated, the segments make rapid contact with each other, resulting in the buzzing sound characteristic of a disturbed rattlesnake.

Life History

Timber rattlesnake accept an active season that runs from late Apr until mid-October. In Northern New York, emergence is frequently delayed until mid-May. Upon emerging from the den, they are rather lethargic and spend most of their time under cover or basking under partly cloudy to sunny skies.

The species is considered migratory, pregnant they originate from a central location and motility out across the mural. Gravid (significant) females drift to gestating habitat- open, rocky ledges where temperatures are college for embryo evolution. Overall, they more often than not migrate from ane.3 to 2.5 miles from their den each summer. Males move the greatest distances through their active season-upwards to 5 miles.

Mating flavour begins in the early summertime and continues into early on autumn. Males are especially active during this time and tin be found using basking and gestating habitat and looking for receptive females. Afterward mating, females store sperm through the wintertime until implantation of the embryos occurs during the following leap as temperatures increase.

Timber rattlesnakes are viviparous, meaning they requite birth to live young. Following a gestation period of 4-5 months, females give nascence to 4-14 (average 9) young every three to five years between late August to mid-September. Neonates (newborn) timber rattlesnakes are almost 10-fourteen inches long at nascency. Each neonate is built-in encased in a transparent membrane, or yolk sac, which is shed within a few minutes.

The young are miniature versions of adults, consummate with hollow fangs, venom and a tiny rattle segment called a "pre-button". Shortly after birth, they shed their skin and driblet their pre-button to reveal the button, or tip of a rattlesnake's rattle. They remain in the surface area with their mother for 1-two weeks until they shed and disperse. In the fall the young follow their parent's olfactory property trail back to the den for the winter.

Timber rattlesnakes are long-lived and reproduce at a low rate, making for irksome population growth. Males may become sexually mature in as few as 5 years, whereas females have longer to attain sexual maturity, between five and xi years. Juvenile mortality is very loftier, only once they reach maturity, the average life span may be between 15 and 20 years, with individuals beingness documented to have lived for more than 50 years in the wild.

Timber rattlesnakes shed their pare once and sometimes twice a year depending on the age of the animal and latitude of the population. A new segment is added to the base of the rattle each time shedding occurs. Snakes with a complete rattle are rarely seen-segments regularly break off during the year.

Rattlesnakes primarily fed on:

• squirrels
• chipmunks
• voles
• mice
• small birds
• amphibians

The venom, which is used primarily to immobilize prey, can be fatal to humans if the bite is untreated. However, in New York there take been no records of human deaths attributed to rattlesnakes in the wild during the concluding several decades. Less than 15% of the snake bites reported over a ten-yr period were actually from a venomous snake. Reverse to popular opinion, a rattlesnake will not pursue or attack a person unless threatened or provoked. Such instances are probable a outcome of the observer being between the snake and information technology'south bespeak of cover. See if yous see a timber rattlesnake beneath.

Distribution and Habitat

The range of the timber rattlesnake extends from southern New Hampshire south through the Appalachian Mountains to northern Florida and w to southeastern Texas and southeastern Nebraska and Wisconsin. Populations are isolated in the Northeast. Historically, the species likely occurred in most mountainous and hilly areas of NYS, except in the college elevations of the Adirondacks, Catskills, and Tug Colina region. They are now found in smaller numbers throughout the country with isolated populations in southeastern New York, the Southern Tier, and in the edges of the eastern Catskills and Adirondacks.

Timber rattlesnakes are more often than not found in deciduous hardwood forests in rugged terrain. They can likewise exist constitute in lowlands, wetlands, or residential areas near dens. Crevices in rocky faces or talus with westerly to easterly southern exposures are used for denning or overwintering. Open up areas with rocky surfaces are used for basking, shedding, and birthing. The surrounding forests provide foraging habitat.

Condition

While abundant in some areas, the timber rattlesnake population has severely declined in numbers and distribution (near 50-75%) in New York State due to unregulated collection, indiscriminate killing, and habitat destruction. Until outlawed in 1971, at that place was a bounty in certain counties in Northern New York for the rattles of these snakes. Even in areas without bounties, the rattlesnake was severely persecuted by local residents. In 1983, timber rattlesnakes were designated as a threatened species.

Despite these conservation efforts, their tedious population growth is further hindered past:

• development
• route mortality
• illegal collecting
• continual disturbance of habitat by recreational users

Collecting timber rattlesnakes from the wild is now prohibited by law under Environmental Conservation Police force xi-0535 and 11-0103(2)(c). Withal, poachers are withal actively supplying the black market pet trade.

Management and Enquiry Needs

The DEC coordinates survey efforts for many of the remaining populations in New York State. These are designed to:

• verify the current condition of known den sites;
• develop baseline estimates of population size;
• determine reproductive success; and
• document whatsoever threats to existing habitat.

New denning locations are currently beingness discovered in areas where the density of overwintering sites is high. Protection and management of habitat is at present a primary concern.

Additional survey work is necessary to verify condition in many populations. Long-term comparative measurements of rattlesnake populations has only been conducted in a unmarried population in NYS. The recent discovery of Serpent Fungal Disease (leaves DEC website) has been noted in several populations of rattlesnake in New York. Further research is necessary to determine the total extent of the impacts of such infections. The touch may be adamant by comparing populations of infected versus non-infected snakes.

If you encounter a timber rattlesnake:

Practice not panic! Keep a safe altitude of 6ft or more than abroad. Let them move forth on their ain. Do not kill or collect the individual. Timber rattlesnakes are not aggressive unless provoked.

If an accidental bite occurs, seek medical attention immediately or telephone call 911. To report sighting, or enquire questions, contact your Regional Wild fauna Office.
