Among the thousands of species of cactus, one really stands above the rest, a species that has become what can only be described as a tree, the Saguaro. They are endemic to the Sonoran desert of Arizona, South-Eastern California, and Northern Mexico, where they form strange forests across the desert slopes. Like most other cacti, the saguaro is a stem succulent, which means they use their thick stems as the main place they store water.
The saguaro is a keystone species in the Sonoran desert with many animals using these plants for food and shelter. The blooms of the saguaro are pollinated by a range of animals, from hummingbirds to bats, with the white winged dove surprisingly being one of the most important. No animal though loves saguaro more than the Gila woodpecker, not only do they enjoy the flower nectar, but they also like to make their nests inside the cactus, drilling cavities that the cactus forms callus tissue around, creating the perfect little cavity for the woodpecker to raise a family. Each season the gila woodpecker creates a new hole, so holes from the previous seasons are available for other birds that love the saguaro, but don’t have the special drilling beak of a woodpecker, like the elf owl, the world's smallest owl.
