(Mesembrinibis cayennensis)
Disppointing views of this and even more disappointing photos, so record shots only. We saw these in Tortugureo NP and again on route to La Fortuna (in the same trees as the Boat-billed Heron).
(Eudocimus albus)
Seen along the road from Equinas Rainforest Lodge during an afternoon walk. Unfortunately quite a distance away, so big crop here.
