A large Tiger Rattlesnake in a loose ambush coil near a series of rodent nests. This one was found just after sunup in a heavily urbanized area. Not all hunting postures for rattlesnakes are simple coils. Rattlesnakes may actively track, then settle in for a relatively short period, then move and set up again. I don’t know if this one succeeded, but it was gone when I passed through the area an hour later.
Several Western Diamondback Rattlesnakes moving around their winter den on a cloudy, warm Spring day near Tucson. These snakes move daily on the surface like this, mostly avoiding detection, for a few weeks during their transition from hibernation to spring hunting. During that time, a lot of social activity takes place.
A Southwestern Speckled Rattlesnake waiting for an unlucky animal to come along in Phoenix. These locations are carefully selected, often after tracking a scent trail for some distance to find an ideal ambush situation.
A Banded Rock Rattlesnake with a pink belly found in southeastern Arizona last year. These small snakes are quick to rattle but seldom stand their ground, opting to flee into bunchgrass or dive into jumbles of rock.
I found this Rosa Boa in central Arizona earlier in the year. This is one of two species of boa that live in Arizona, which is a surprise to many who live here. They’re relatively small, typically around 2 feet long, and harmless to people (unless you consider an occasional minor nip “harm”). This one was photographed and left to crawl under the boulder and disappear.
