Our goal the morning of Friday, January 20, 2012, was to set foot on terra firma at a private reserve near the village of El Tucan for some birding on solid ground. The village is located about fifteen minutes above the town of Nauta on the Rio Marañon. To say this birding adventure was a disappointment would be an understatement. There were few birds (Plain-throated Antwren, Blue-crowned Manakin, and Broad-billed Motmot), and those that were around were difficult to see. Plus, swarms of millions of mosquitoes and steep and slippery trails made this one adventure we won't soon forget. However, all was not lost...as we got good looks at the ventral side of a lovely Caligo sp. or Owl Butterfly. Temperatures were in the low 80's with overcast skies and high humidity.
