Spring changes Iguaçu National Park: trees in bloom and more birds on the trails

The concessionaire points to flowering, fruiting and more active wildlife this time of year
Spring is the most biologically active season at Iguaçu National Park, on the Brazilian side: ipê trees bloom, the Atlantic Forest puts out new leaves and fruit, and wildlife enters its breeding period, so birds and mammals are easier to spot along the trails.
Urbia+Cataratas, the concessionaire that runs visits to Iguaçu National Park alongside ICMBio, points to spring as the park's most biologically active season. As temperatures rise, the forest flowers and fruits at the same time, and that supply of flowers and fruit draws wildlife closer to the trails.
What changes in the landscape
The ipê tree is the visual highlight of the season. Flowering comes with new leaves and the fruiting of Atlantic Forest species, the park's biome. The park records more than 700 species of land plants and around 800 butterfly species, according to the concessionaire.
Which animals show up more
Breeding activity makes birds noisier and more mobile. The concessionaire lists the surucua trogon, black-throated trogon and green-backed trogon, plus toucans, hummingbirds, oropendolas, solitary tinamou and swifts. Among mammals, coatis and capuchin monkeys get more active with food around.
Remember that feeding animals in the park is banned, and with coatis the official guidance is to keep food sealed inside a closed backpack.
Where to see it
The stretches the concessionaire mentions are the Falls Trail, the São João Circuit, the Bananeiras Path and the Falls Cycle Path. Check the status before you head out, because some trails close for wildlife management or flooding: the Canafístula Trail is closed until 12 October for wildlife monitoring, and the detail of each route is in trails of the national park.
The river this week
This spring arrives with a high river. Our reading from the National Water Agency (ANA) gauge next to Hotel Cataratas was 3,750 m³/s on 29 September, about 2.5 times the historical average of 1,500 m³/s, and rising. High flow means fuller falls and a wetter viewpoint, and walkway closures on the Brazilian side usually only happen near 9,000 m³/s. On the Argentine side, the Devil's Throat has been closed since 3 August for the precautionary removal of the walkways, with no reopening date.
Today's measurement is at how the Falls are today and visiting status at are Iguaçu Falls open today.
