Description

The Mexican Spotted Owl is notably one of the three subspecies of spotted owls with the other two including the Northern Spotted Owl and the California Spotted Owl.  Unlike its two counterparts, the Mexican spotted owl is recognized as one of the largest owls in North America due to having an average length of 16-19 inches, a wingspan of 42-45 inches, and an average weight of about 19.5-23 ounces. One interesting feature of this species is that females are actually larger than males, however both exhibit a similar physical appearance. While stumbling upon one of these astonishing birds, you may find yourself captivated by its large dark eyes, a characteristic that distinguishes it from other owls .The Mexican spotted owl lacks ear tufts and is a chestnut brown color with irregular white spots scattered throughout its back, abdomen, and head. The white spots are larger in size and more abundant in comparison to the other two subspecies which causes the Mexican spotted owl to appear much lighter. The wings and tail feathers are dark brown and are marked with  thin white bands.
