This was a surprise... not well known from Beni.

GREAT PAMPA-FINCH (EASTERN) (Embernagra platensis platensis)

Although very similar looking to the form we saw in the Andes on the main tour, this population is a different-voiced lowland form... no doubt best considered a different species (once someone does the study!).

BLUE-BLACK GRASSQUIT (Volatinia jacarina)

WHITE-BELLIED SEEDEATER (BICOLORED) (Sporophila leucoptera bicolor)

DARK-THROATED SEEDEATER (Sporophila ruficollis)

We didn't actually confirm this ID, but we saw non-male birds of this complex (with Tawny-rumped and Rufous-rumped). From previous experience here, Dark-throated is the most common, so I'm shuffling the sighting under this name for convenience-sake.

Some brief glimpses.

SOUTH AMERICAN COATI (Nasua nasua)
