Black and green African mamba snakes

This 8 March 2020 video says about itself:

Mambas are the most feared snakes of Africa. People think that they can chase people and try to bite them. However, when it comes to snakebites, there are other snakes, like cobras and puff adders, which are responsible for most cases. Watch this video, to actually see, how beautiful are mambas. You will see 3 species in the wild:

Black mamba (Dendroaspis polylepis)
Jameson’s mamba (Dendroaspis jamesoni)
Eastern Green mamba (Dendroaspis angusticeps)

This 2018 video is about a Jameson’s mamba in Uganda.
