Stealthy megafauna

Recently in the news: Tens of thousands of previously unknown gorillas uncovered by intensive surveys in the forests and swamps of two areas in the Republic of Congo. Wow, just imagine that, huge numbers of large, vocal, charismatic primates overlooked for years and years in the remote forest stretches of what can hardly be described as a sparsely populated region of the continent. Only a fool would have believed this was possible, it is clearly an absurd idea. And yet, it happened.

If these huge numbers of great apes were missed for so long, just imagine how easy it might be to overlook a tiny population of a much smaller and more mobile species for years, even decades...
