Cape Verde is one of the few Land masses on the world which has a zero percent population of snakes (excluding pets) there are no snakes on the cape verde islands and not many other dangerous animals either.
No. Cape Verde used to be a Portuguese Colony and is now an independent African archipelago country. There is nothing Spanish about Cape Verde. However, the Canary Islands archipelago to the north of Cape Verde are Spanish sovereign territory.
Verde means green, so it could mean a green bird, or by a big leap of imagination it could also mean a bird that is unique to the Cape Verde islands. Like the Alexander's Swift, Raso Lark, Cape Verde Warbler, and the Iago Sparrow.
