What visitors say
Nearby we found a pair of Slate-Coloured Grosbeak (Saltator grossus) and in a clearing nearer to San Martin village, a Fulvous Shrike-Tanager (Lanio fulvus).
I saw what was clearly a jacamar, but one I had never seen before, even in the bird guides!
Our destination was Casa Gregorio, an ecolodge that sits along San Martín’s western edge, a few hundred feet from the Amacayacu River.
