Our 2nd excursion at Cristalino was in the afternoon of the 1st full day we were there (sadly we could only afford 2 nights).  We went in a small boat down river to an island called Ilha Ariosto in the middle of the river that had some amazing birdlife!  I wasn’t able to get photos of most of them as the sightings were mostly fly-bys.  I barely caught a glimpse of a Severe Macaw (Chestnut-fronted Macaw) as he zoomed overhead.  The Dusky-billed Parrotlets were a bit more co-operative with one posing on a branch.  There were quite a few other birds that I didn’t write down and it was especially nice to see hummingbirds out in the bush with no plastic feeders in sight.  We had been hoping for Umbrellabirds but coudn’t find any.
