Every evening between 17:30 and 18:45, tens of thousands of scarlet ibis return to a single island nursery in the Parnaíba Delta, their flight paths converging from feeding grounds scattered across 2,700 square kilometers of mangrove and tidal plain. The revoada dos guarás tutóia — literally the 'flight of the scarlet ibis' — is one of the largest nightly congregations of Eudocimus ruber in South America, a spectacle driven by millennia of colonial nesting behavior and the Delta's unique position at the confluence of the Parnaíba, Timonha, and Ubatuba rivers. The phenomenon exists because the mangrove islands offer predator-free roosting; caimans cannot reach the canopy, and terrestrial mammals are blocked by the labyrinth of channels that separate the nesting sites from the mainland. The Delta itself is the only open-delta system in the Americas, a 70-kilometer fan of alluvial islands where river water meets the Atlantic in a slow braiding of sediment and salt. Unlike closed deltas that terminate in a single bay, Parnaíba's five mouths distribute water across a lattice of 80-plus islands, many unnamed, most uninhabited. This fragmented geography created ideal conditions for the ibis colonies: isolation without aridity, tidal rhythm without storm surge. By the time Portuguese navigators charted the coast in the 1570s, indigenous Tremembé communities had already named the scarlet ibis guarás and centered seasonal migrations around the birds' arrival each July. Today the revoada is visible only by boat, as the primary nesting island sits four kilometers from the nearest road-accessible shore. Speedboat circuits and traditional voadeira launches depart from Tutóia's riverfront between 14:00 and 16:00, timing their arrival to coincide with the birds' return as the equatorial sun drops below 15 degrees elevation. The ibis navigate by solar angle and tidal cue, their crimson plumage — derived from carotenoid pigments in the crustaceans they consume — appearing almost luminous against the green-black mangrove and the violet gradient of coastal twilight. Biologists estimate the Tutóia colony fluctuates between 18,000 and 35,000 individuals depending on rainfall patterns in the interior basin, where the birds forage in seasonal wetlands up to 60 kilometers inland. The revoada dos guarás tutóia tour circuit has become the Delta's signature wildlife encounter, a 90-minute passage through tidal channels that frame one of the tropics' most reliable avian gatherings.
"Tens of thousands of scarlet ibis return to a single island nursery every evening, their flight paths converging across 2,700 square kilometers of mangrove."
A step-by-step walkthrough of the visit — what you'll see, how long each stage takes, and the details that matter.
You leave Tutóia's wooden dock mid-afternoon, the voadeira's outboard pushing against the falling tide as the guide steers into the first channel. The mangrove walls rise three meters on either side, their pneumatophore roots breaking the water like miniature spires. Twenty minutes in, the channel widens into a lagoon fringed by buriti palms, and the boat slows to drift speed. The first ibis appear as distant flecks, then as cohesive flocks — ribbons of crimson threading the sky from the southeast. By 17:45 the voadeira is anchored 200 meters from the nesting island, engines cut, and the air fills with the sound of wings and guttural calls. Wave after wave of ibis descend into the canopy, the branches bending under the collective weight. You count twelve flocks in five minutes, each flock numbering in the hundreds, the sky rotating through shades of tangerine and indigo as the sun drops behind the dunes of Tutóia. The guide points out juvenile birds — their plumage still mottled brown and white — landing beside breeding adults whose crimson is so saturated it registers almost as black in the failing light. The return lasts 40 minutes, the density peaking just after sunset, and then the voadeira turns back toward the village, the mangrove channels now silhouetted against the last pale band of horizon.
The area is accessible daily from 14:00–19:00. These hours allow for optimal sunset observation of the scarlet ibises.
No, the entrance fee is 0 BRL. Visitors only pay for the boat service to reach the viewing area.
The best arrival window is 14:30–15:30 to reach the nesting areas. This ensures you are in position before the birds return at sunset.
