Extinct moa birds of New Zealand

This 16 February 2020 video says about itself:

Moa were a fascinating and diverse group of birds that possess numerous anatomical and biological characteristics that are not found in any other bird species. Coming in many different shapes and sizes, from the agile Upland moa to the hulking Heavy-footed moa. With this video, I hope you learn something new about this remarkable group and gain a greater appreciation for New Zealand’s endemic fauna.
