I knew it had probably been close to 40 years since I had been to southern Arizona where you can see the Saguaro cactus. These cactus only grow in southern AZ, a little bit of CA and some of the country of Mexico. Some of the Saguaros are over hundreds of years old as it takes that long to get that big. It is nothing for one to be 50 to 75 feet talk. There are long spines all up and down the cactus. Of course it was the wrong time of year to see them blooming which is usually in the spring. They are a big beautiful white blossom. Saguaro's can be home to many different birds and some small mammals and reptiles. Woodpeckers are known for hollowing out small holes in the Saguaro's so they can nest in the. Owls, wrens, mockingbirds also nest in Saguaro's.
