A Birder’s Paradise
No other country in the world has as many bird species in such a small land area. With a list of over 1,630 species, Ecuador ranks fourth in the world in bird diversity. Fourteen species are found only within the boundaries of Ecuador.
Moreover, Ecuador holds the world’s top two Endemic Bird Areas (EBAs), the Choco and Tumbesian, within a short distance from each other. Nowhere else in the world are such distinct bird species in such close proximity. The Choco is best accessed from Quito and in a one-week trip you can see over 300 species. The main birding areas in the Choco are the Tandayapa Valley, Mindo Valley, Milpe Bird Reserve, Rio Silanche Bird Reserve and the Canande region of far Northwest Ecuador.

Looking forward to the additional parts… Birds are nice, but not a strong enough case to take the risks you pointed out on previous posts. IMO, of course,
Ah yes, but that is just part one! Stay tuned. Ecuador is a very diverse place. You will soon see!
