During our 2 night stay at Cristalino, we had 3 guided excursions to different places.  This one was on the first morning we were there and we took a small boat a few minutes down river and hiked up a hill. Then we went to a second place that had a watering hole but there weren’t many birds there, mostly butterflies.   I didn’t get many photos from this excursion and I didn’t write down the species so just enjoy the pictorial as an example of what to expect!
