C. undulatus

C. undulatus is the scientific name for the parakeet species commonly known as the Monk Parakeet or Quaker Parrot. It is a highly social, intelligent bird originally from South America. Recognizable by its green body with a greyish face and breast, it often exhibits a striking wavy feather pattern, hence the name "undulatus," meaning "wavy." These birds are known for building large, communal nests out of twigs, often in urban areas outside their native range. They are popular as pets due to their social behavior and ability to mimic sounds, but they can also establish invasive populations when released into the wild.
