Animal Events

🦌

Brown-throated Sloth Canopy Foraging in Flooded Igapó

Apr

Rising floodwaters force sloths to navigate dense upper canopy branches, where they actively feed on emergent tender leaves and fruit.

LC Endemic

Bradypus variegatus

30–40% · Possible

🦎

Black Caiman Dry Season Basking and Nesting

Mar

Exposed sandbanks and drying mudflats during early seasonal changes provide optimal environments for large caimans to bask and prepare nesting sites.

Caiman crocodilus

30–40% · Possible

Melanosuchus niger

40–50% · Likely

🦌

Boto River Dolphin Feeding and Low Water Concentration

Aug

As dry season water levels drop, fish concentrate in shrinking channels, drawing high numbers of Boto river dolphins to feed actively near sandbanks and river edges.

Sotalia fluviatilis

10–20% · Possible
