In Brief


Beni Savanna, Bolivia


To protect and increase the population of the Blue-throated Macaw and other species of the Beni Savanna ecosystem through conservation at Barba Azul Nature Reserve.


The Crticially Endangered Blue-throated Macaw is found only in the Beni Savanna of Bolivia, where if faces ongoing loss of its habitat from conversion for cattle ranching.

Size of Area Involved:

11,000 hectares/110 km2 (27,266 acres)

Compare with: Manhattan Island is 60 km2

Support this project

Actions & Results:

  • ICFC contributed to the purchase of a strategic property to double the size of the reserve in 2013.
  • Fenced portions of the reserve are now cattle free; firebreaks prevent the spread of human-caused fires, allowing the savanna ecosystem to function naturally.
  • Palm island habitats provide the macaw's chief food of Motacu palm fruits, but some lack regeneration because of cattle grazing. Preparatory work has been done toward fencing and transplanting palm seedlings on the islands.


2016 budget: US$15,000; Cumulative cost to ICFC (past years): reserve management and tractor purchase $86,619; land acquisition $35,000 (out of US$430,000)

Project Partners and Personnel

Our field partner is the Bolivian organization Asociación Armonía, which owns and manages Barba Azul Nature Reserve.

Asociación Armonía is a Bolivian accredited non-profit conservation organization created in 1993. It is supported by the regional governments of Beni and Santa Cruz and the Bolivian national park administration (SERNAP). In 2009, Armonía received a certificate of commendation from the Bolivian government for its efforts to protect Bolivia's birds and their habitats. Armonía manages twenty conservation programs, including twelve programs with threatened species. Key personnel are Bennett Hennessey, executive director and Tjaille Boorsma, Barba Azul reserve manager. Rene Cartagena and Hernan Lopez work on reserve protection. Rosario Cortez manages the field station and attends to visiting tourists.


The Critically Endangered Blue-throated Macaw is found in only one place on Earth: the Beni Savanna in northern Bolivia. Extending over 126,100 sq km, this complex ecosystem of grasslands, marshes, forest islands and gallery forest supports a diverse and distinctive flora and fauna. A 2009 survey found 230 bird species, including many waterbirds and several species of North American migrants. As many as 1000 Buff-breasted Sandpipers (a Near Threatened species) were counted there recently, making this the most important stop-over site in Bolivia. Of its 146 mammal species (see mammal video, below), several are found nowhere else in Amazonia, including the Pampas Deer, the Near Threatened Maned Wolf, and the Endangered Beni Titi Monkey. Also present are the Southern Tamandua, Black Howler Monkey, Capybara, Jaguar and high concentrations of Giant Anteater.

The Beni is entirely privately owned, mainly by ranchers. Much of it is being degraded by overgrazing, planting non-native grasses, and aggressive fire management, as each year more of this habitat is lost to intentional burning for pastureland.

The Blue-throated Macaw, whose Spanish name, Barba Azul, means blue beard, was shrouded in mystery until recently. Known from cage birds captured from the wild and from paintings and specimen collections, its range was finally pinned down to the Beni Savanna. There, it depends on palm trees for nesting sites. The macaw faces threats from the illegal pet trade and degradation of its habitat. In particular, the burning of forests kills palm seedlings, resulting in fewer palms for the birds to use for nesting.

In 2008, with support from American Bird Conservancy and World Land Trust-US (now Rainforest Trust), the Bolivian conservation organization Asociación Armonía was able to purchase land for the Barba Azul Nature Reserve, creating the first protected area for the Blue-throated Macaw, whose wild population is believed to number only 350 individuals. The impetus for the reserve was the finding of a thriving colony of at least 80 birds (now numbering about 100), whereas previous surveys had turned up only small groups of 2-3 pairs. The first step was the removal of cattle from the reserve.

When the adjacent Santa Anita ranch came on the market, several conservation organizations including ICFC took advantage of a great opportunity to double the size of the reserve. With almost one third of the population of Blue-throated Macaws, this property is a valuable addition.

About 100 macaws pass 6-8 months on the reserve during the dry season, then disperse elsewhere to nest during the rainy season. Nest boxes erected at the reserve have yet to be adopted by macaws, although other species have used them. In the Marban area, Armonia has had success in having this species adopt next boxes, which appears to have led to an increase in population there. We have strong hopes that macaws will start using nest boxes at Barba Azul, which will be a huge step in placing the species on a more secure footing and reducing extinction risk.

Actions and Results

Land Acquisition

The purchase of the 6358-ha Santa Anita ranch was completed in 2013, bringing the total reserve to just over 11,000 ha. Other contributors, in addition to Rainforest Trust (a lead supporter of the reserve) and ICFC were: American Bird Conservancy, Patricia and David Davidson, IUCN National Committee of the Netherlands (supported by the Dutch Postcode Lottery), Loro Parque Fundación, Neotropical Migratory Bird Conservation Act program of the U.S. Fish and Wildlife Service, Robert Wilson Charitable Trust, and World Land Trust.

ICFC is confident in the ability of Asociación Armonía to protect and manage the reserve. ICFC maintains the ability to defend the permanent conservation use of the acquired land to which we contributed through use of a mortgage on the land aimed at that purpose.

Reserve Management

Much has been accomplished in the reserve's short history:

  • In 2015, ICFC and American Bird Conservancy purchased a John Deere tractor — a key conservation tool! In just 6 months, the tractor enabled:
    1. the creation of 30 km of firebreaks (without firebreaks, much more savanna burns each year than the natural amount of 5-10%);
    2. installation of 4 km of fencing along the entire southern border of the reserve to keep out cattle;nstallation of 10 new nest boxes for Blue-throated Macaw in the most inaccessible corners of the reserve and access to remote parts of the reserve for other purposes.
    3. More generally, fencing has been important, as has having a cowboy on staff at the reserve to constantly deal with invading cattle and neighbouring cowboys.
  • Nest boxes placed in the reserve since 2010 have not yet been used for nesting by Blue-throated Macaws, but have been used by other species including Crane Hawk, Barn Owl, Toco Toucan and White-eyed Parakeets. In 2011, another twenty nest boxes were established for the threatened Orinoco Goose.
  • A biological station was established in the reserve to enable continued research, monitoring and protection. Graduate students are conducting a variety of ecological research that will provide a basis for refining reserve management.
  • Ecotourism is being developed, with 141 tourist nights logged in 2015.
  • A small nursery was established and Motacu palm seedlings will be moved from the nursery to newly created forest islands and islands undergoing restoration.
  • Asociación Armonía has reduced illegal trade in Blue-throated Macaws through education and media campaigns.

Buff-breasted Sandpipers at Barba Azul

A significant portion of the Barba Azul Beni Savannah provides an important migratory stop-over for Buff-breasted Sandpipers during their annual southbound migration en route for Brazil. Up to 1,500 Buff-breasted Sandpipers land at Barba Azul to rest and find food after departing Colombia and crossing non-stop over the immense Amazon basin. Our partners at Barba Azul are now actively managing this species' habitat with the aim to protect these birds from disturbance and provide optimal foraging conditions.
