It was a great trip for 'Antthings', Antshrikes in particular. We had:

Spot-backed (Atlantic Forest endemic)
Giant (totally awesome bird)
Tufted (seen by a couple, heard-only by me)
Chestnut-backed (most common)
Sooretema Slaty-Antshrike (Brazilian endemic)
Variable Antshrike
Rufous-capped Antshike
Barred Antshrike
Great Antshrike
