Woodrats, also known as packrats, look like typical rats except that they have hairy tails versus scaly, hairless ones. While there are numerous species throughout the US, there are three found in northern NM: the bushy-tailed, Mexican, and white-throated with the white-throated most common locally. Woodrats are typically loners living in dens used for nesting and food storage. They eat plant materials, insects, and even small reptiles.
