New bird and rediscovered tree rat

I'm pleased to give credit to the blog Cryptomundo for catching these two major finds. Birds and mammals are the groups generally considered best-known: various experts at various times have declared them virtually all catalogued. But birds keep coming at a steady rate, and the discovery curve for mammals is actually trending up.
So it is we have a new rail from Madagascar and the rediscovery of a strikingly colored tree rat from Columbia not seen since 1898. The tree rat just sort of walked into view, ambling along a hand rail at a nature center. From the Beanka forest in western Madagascar - and area where the terrain is so steep the forest has yet to be logged - comes the rail Mentocrex beankaensis, courtesy of scientists from the Field Museum. Keep your eyes open, everyone. Discoveries are everywhere.
