Birding Northeast Argentina: Iberá Marshlands and Iguazú National Park

Birding Northeast Argentina: Iberá Marshlands and Iguazú National Park

November 2025/2026

In the Corrientes province in the north-eastern reaches of Argentina there is a vast region locally known as the Iberá Marshlands, which is the largest wetland area in South America after the Pantanal in Brazil. Iberá, or as the Guaraní natives call it “Shining Waters”, is a BirdLife International IBA and Ramsar Site as well as a national preserve. It covers an area nearly three times the size of the American Everglades and protects a multitude of fauna and flora occurring in such diverse habitats as lakes and swamps, palm groves, expansive grasslands, and climax forests. Over 330 bird species, including Jabiru, Snail Kite, Southern Screamer, Greater Rhea, Savanna Hawk, Black-collared Hawk, White Woodpecker, Scarlet-headed Blackbird, and Red-crested Cardinal, as well as other animals such as Capybara, Marsh Deer, Maned Wolf, Black-and-gold Howler Monkey, Big Hairy Armadillo, Yellow Anaconda, and Yacaré Caiman, are all to be found.

The legendary “Gauchos” (Argentine cowboys) also call Iberá home; these “cowboys” live and work on the vast cattle ranches known as “estancias”, where they still use their traditional equestrian culture in daily life. It’s on some of these “estancias” that we’ll be staying to explore the region, as the hotels are few and far between.

Yellow-fronted Woodpecker is one of a number of spectacular woodpecker species we may see on this tour.

Come and explore this captivating paradise, combined with the fascinating Iguazú Falls, close to the border of Brazil. We’ll be spending three days in the spectacular Iguazú National Park on both the Argentinian and Brazilian sides, where birds include the likes of Black-fronted Piping Guan, Toco Toucan, Chestnut-eared Aracari, Scaly-headed Parrot, Blue-winged Parrotlet, Plumbeous Kite, Tropical Screech Owl, Short-tailed Nighthawk, Great Dusky Swift, Scale-throated Hermit, Black-throated Mango, Fork-tailed Woodnymph, Surucua Trogon, Yellow-fronted Woodpecker, and Tufted Antshrike among many more.

This tour can be combined with our preceding  Birding Tour Argentina: Northwest from the foothills to puna, and/or our following Birding Tour Argentina: Southern Patagonia – Los Glaciares National Park and Austral Rail.

This ranch is found in the northwest corner of the Iberá Marshlands, which is considered the Argentinean Pantanal.

Day 10. Transfer to Buenos Aires, departure

Today is mostly a travel day as we’ll be driving to Puerto Iguazú to catch our flight to Buenos Aires, where everyone will connect with their international flights or continue onto their next birding trip in Argentina.

Please note that the itinerary cannot be guaranteed as it is only a rough guide and can be changed (usually slightly) due to factors such as availability of accommodation, updated information on the state of accommodation, roads, or birding sites, the discretion of the guides and other factors. In addition, we sometimes have to use a different international guide from the one advertised due to tour scheduling.

‘My trip to Argentina was amazing! We always see huge numbers of species on Birding Ecotours trips, and this one was no exception. Add to that the scenery in the Andes, among the most spectacular anywhere; meanwhile, accommodations, arrangements, and guiding were fully up to Birding Ecotours’ usual standards. Eduardo is a great guide, always watching out for our welfare as well as finding the birds, and Diego was one of the more knowledgeable – and friendly – local guides we have had in years. As my trip focused on the northwest, I look forward to visiting the rest of this wonderful country soon.’
