It seems that right now we are looking at 2018 instead of this year. We hope to do one week on a boat and possibly another week in the area. Part of the company are non-birders, so it will have to be balanced.
Thank you Temmie,
I also did some searching yesterday. There is a commercial site with some info: http://www.brazilnaturetours.com/brazil-tours/manaus - look at the 4 package options near the end of the page.
I know nothing about this area, so seeking some info. We are talking about flying to Manaus and hoping that there is a possibility of doing a sort of mini cruise on the river. We would love for it to be a smallish boat with other people that are somehow interested in nature, obviously...
