Until recent mitochondrial DNA evidence, "P. hernandesi" was considered to be the same species as "P. douglasii". They are now considered distinct species with the pygmy short-horned lizard ("P. douglasii" ) occupying the northwest portion of the United States and extreme southern British Columbia. When placed together the two are easily distinguished at full size, the pygmy short-horned lizard being much smaller. "P. hernandesi" is a highly variable species with different geographic populations
Horned coot is generally a low-density species and the total population has been estimated at 10,000–20,000, with as few as 620 in the Chilean part of its range. Consequently, it is considered to be near threatened by BirdLife International and IUCN. Horned coot The horned coot ("Fulica cornuta") is a species of bird found in the Andes of South America.
