Many thanks to everybody who commented with suggestions on my last post, the final version is now out there:
I expect there will probably be disagreements about what’s on there, and it is a highly subjective topic. As some comments rightly pointed out, a list like the Big 5 is a blend of difficulty of spotting and iconic-ness, both of which aren’t exactly quantifiable. I kind of backtracked on making it purely about difficulty, plus one of the intended audiences is broader wildlife tourists so I had to exclude more obscure species that they may not have heard of like giant otter shrew or bush dog.
Anyways, thanks again to everyone who commented with advice and with their own personal takes, and a broader thanks to everybody who’s submitted info in their trip reports on finding these animals!
