There is an abundance of wildlife in Costa Rica, and while traveling with a naturalist guide, we were shown the best hiding places for elusive animals. Though I usually looked to the trees for birdlife—quetzals, toucans, toucanets, hummingbirds, motmots, and more—one look up led me to this Mexican hairy porcupine (Coendou mexicanus). A nocturnal, arboreal, solitary animal, the porcupine was slumbering in a tree when we found it hidden amongst the branches.
