All the snake species tested have had the same initial response to human presence. If given the opportunity, they escape--down a hole, under a ledge, or in the case of cottonmouths, into the water. Escape is even the standard behavior of enormous diamondback rattlesnakes, which will immediately disappear if they have enough warning before they think a person can reach them.
But often escape is not possible, so most snakes hold their ground, ready to defend themselves. A difference between copperheads and the other species appears in the next phase, when they are approached. Most rattlesnakes vibrate their tails and most cottonmouths sit with mouth open when a human comes near. Even some non-venomous snakes vibrate their tails. These displays are merely warnings not to tread on them. They are not aggressive attack measures. The snakes just want us to leave them alone.
So far, the dozens of cottonmouths Dr. Gibbons stood beside have made threat displays but have not bitten the researcher's boot. The same has been true for canebrake rattlesnakes although too few have been tested to declare that they are as passive as cottonmouths. The exciting news (at least for the researchers) is that the copperhead is different from the others. Most copperheads tested have struck out immediately when they felt threatened.
This behavior explains why more people receive legitimate snakebites from copperheads than from any other species of venomous snake in North America. Still to be investigated is another aspect of copperhead bites: many are not serious enough to require more than minor medical treatment. This may be so not only because the venom of a copperhead is significantly less potent than that of rattlesnakes or cottonmouths, but also because they seldom inject much venom.
The copperhead's initial threat display is to strike. It lashes out at an enemy as a warning. If the enemy is close enough, the fangs may penetrate the skin. However, because this is a threat display, not an attempt to kill, the snake injects little venom. A copperhead has no intention of wasting valuable venom if it can scare away the menace with a minor bite.
