What kind of Rat?

November 9, 2015

A Pack Rat, that’s what!

More specifically, a White-throated Woodrat, Neotoma albigula.

There are several different kinds of related Woodrats, just to make things confusing for humans. And in addition, Woodrats are not the same as the rats we usually think of, when we think of rats–those are the Old World Rattus rats.

Woodrats or Pack Rats look more like giganto mice, with their big ears and big dark eyes. Their tails are also fuzzier than the bare Rattus tails.Packrat

These amazing creatures can survive on the moisture they get from the vegetation they eat, and do not need to drink water. How’s that for a desert adaptation!

Quite a while back we talked about Pack Rat middens, the amazing homes the White-throated Woodrats build in the desert.

These folks must have special skills, to build such large defensive structures without getting nasty stab wounds, since middens often include a lot of cactus branches.

Packrat Middens

November 3, 2013

Packrats, Neotoma albigula, make interesting nests in which to store their treasures—and themselves.

When you are out in the desert, the trick is how to spot a packrat nest. It’s not always easy. I guess that’s the idea, when you are building a hideaway.  Basically, look for a crazy, almost random pile of sticks and leaves, and often cholla cactus stems. The nests can range from a foot to 8 feet wide, and are often at the base of a shrub or cactus.

Apparently, If you went inside a packrat nest or midden, an activity the packrats vigorously discourage, you might find shiny bits of human treasures—foil, metal, or other bright objects, since packrats seem to like shiny things as much as we do.

Packrats do like cholla cacti, somehow managing to avoid their really nasty and determined thorns. There’s even one variety called the jumping cholla—I would stay away from those! The name comes from how easily a stem can get detached and glom onto you. A packrat favorite! Cholla stems are certainly a good defensive addition to a habitation—the dry stems are probably even nastier than green ones. According to the Desert Museum, packrats love to eat prickly pear fruit. So they are really cactus creatures.
