Chaco Birding in Brazil: Porto Murtinho Expeditions for Chaco Specialities
Chaco Birding in Brazil (Porto Murtinho)
Private 1–3 day expeditions into the only stretch of Chaco within Brazilian territory, at Porto Murtinho on the banks of the Paraguay River, led by biologist and guide Lucas Yanai.
In the far southwest of Mato Grosso do Sul, in Porto Murtinho, Brazil meets the Chaco — a biome still little explored within the country, yet strategically rich for birdwatching. On the banks of the Paraguay River, a natural corridor linking different regions of South America, the area hosts specialised species rarely recorded in other Brazilian destinations.
With vegetation adapted to climatic extremes, low forests and dry formations, the Chaco offers a landscape distinct from the Cerrado and the Pantanal. Its border location and proximity to continental migratory routes further enhance its potential for unique sightings throughout the year.
Seasonality directly influences access, environmental dynamics and species presence. Careful planning with a specialised guide is essential to select the most suitable period and maximise observation opportunities. The Brazilian Chaco is more than an itinerary extension — it is a biogeographical frontier where every field outing holds real discovery potential.

Why the Brazilian Chaco is a biogeographic frontier
In the far southwest of Mato Grosso do Sul, at Porto Murtinho, Brazil meets the Chaco — a biome that covers large areas of Paraguay, Bolivia and Argentina but is confined, within Brazil, to this narrow strip. For birders that means something very concrete: there are species here that are barely recorded anywhere else in the country.
The vegetation is adapted to extremes: low forest, dry formations and soils that go from waterlogged to cracked over the course of a year. The landscape is visibly different from the Cerrado and the Pantanal, and the birdlife follows that difference — whole families behave differently here.
The banks of the Paraguay River act as a natural corridor, linking distant regions of South America and bringing, along with continental migratory routes, records that fall outside the expected. That is why the Chaco rewards birders who already know the Pantanal and want to add genuinely new species to the list.
Seasonality weighs heavily: access, environmental dynamics and species presence all shift sharply through the year. Planning with a specialised guide is not a convenience here — it is what determines the outcome of the expedition.
Best time for birdwatching in the Chaco
The Chaco is the most seasonal of our three destinations, and the recommended window is narrower.
Dry season, July to October — the recommended window
This is when access is reliable and bird activity is most predictable. July and August bring cool nights and dry days; September and October get considerably hotter, which means earlier starts and a long midday break.
Wet season, November to March — limited access
Rain transforms the terrain and access routes can become impassable. This is not the season we recommend for a first visit to the Chaco; if your dates fall here, we will talk through what is realistic before you commit.
Brazilian Chaco specialities

Chaco Puffbird
Nystalus striatipectus
One of the most representative birds of the biome — discreet and patient, often perched motionless on an exposed branch.

Black-capped Warbling Finch
Microspingus melanoleucus
A Chaco speciality and one of the expedition's target species, tied to the dry formations and low vegetation of the region.

Nanday Parakeet
Aratinga nenday
A parakeet species characteristic of the transition zone between the Brazilian Chaco and the Pantanal.

Jabiru
Jabiru mycteria
The great stork of the Pantanal also reaches the Chaco wetlands along the Paraguay River — a reminder of how closely the two biomes meet here.
What is included
- Cadastur-certified biologist guide (Lucas Yanai) throughout the expedition, in English, Portuguese or Spanish.
- Itinerary planning around your dates, pace, experience level and target species list.
- Field identification support and a list of species recorded by the end of the tour.
- Adventure insurance, included in all tours.
- Free cancellation up to 30 days before the tour date, and free rescheduling in case of adverse weather.
- Airport transfer and transport logistics arranged, once you share your flight details.
Practical information for reaching the Chaco
- Campo Grande (CGR) is the reference international airport, with the most connections; the expedition departs from there or from Bonito.
- Porto Murtinho sits in the far southwest of the state, on the banks of the Paraguay River. It is the most remote of the three tours and involves more travel time.
- Citizens of the EU, USA, UK, Canada, Australia and Japan do not need a visa for stays of up to 90 days in Brazil.
- Come prepared for strong heat and direct sun: plenty of water, sunscreen, a hat, light long sleeves in neutral colours and closed footwear for dry terrain.
