The timber rattlesnake is a venomous pit viper that lives in forests and rocky land in the eastern United States. It is the only rattlesnake in most of the crowded northeastern states, and it is one of the most northerly venomous snakes in North America.1

Tuis

It lives in deciduous forests in rugged terrain, as well as lowland cane thickets, swamp edges, river floodplains, hardwood and pine forests, mountains and rural farmland. In winter it shelters in dens and limestone crevices, and in summer pregnant females favour open, rocky ledges.1

Wat eet dit?

It eats mainly small mammals such as mice, rats, squirrels and rabbits, and sometimes small birds and frogs. It waits in ambush, often on fallen logs, then strikes and follows its prey until it can eat it.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

Its venom is extremely potent and can be haemorrhagic (damaging blood vessels and causing bleeding) or neurotoxic (attacking the nerves), depending on the population and location. Its long fangs, large size and high venom yield make it potentially one of North America's most dangerous snakes. Venom-induced incapacitation can progress rapidly.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

It is potentially one of North America's most dangerous snakes, but it is usually shy and calm. It will retreat if it can and attacks mainly when cornered. Over many years in western Pennsylvania, one naturalist heard of only one death from its bite. Bites are widespread in some areas of Iowa's forests. Its remote, wooded habitat can make emergency medical care difficult or even impossible.1

Wat doen dit as dit bang is?

It rattles and feints a good deal before striking, and it will try to retreat first if it feels threatened.1

As dit byt

Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Timber rattlesnakes return to the same winter den each year, and juveniles can track chemical cues to find relatives in it.1

Female timber rattlesnakes bask in the sun on open rocky areas called basking knolls before they give birth.1

They share winter dens with copperheads and rat snakes.1

It is the only rattlesnake in most of the populous Northeastern United States, and one of the most northerly venomous snakes in North America.1

Males often mate farther from the winter dens than females do.1

Mite-breker

Mite: Rattlesnakes attack people as soon as they see them.

Waarheid: Timber rattlesnakes are shy and will try to retreat from danger first. They attack mainly when they are cornered, so leaving them alone keeps people safe.1
