The hyacinth macaw (Anodorhynchus hyacinthinus) is the largest species of parrot in the world. Its striking cobalt blue plumage makes it a highly sought after pet. However, trapping for the pet trade along with habitat loss has led to a dramatic decline of hyacinth macaw numbers in the wild. Today, the species is endangered and in need of greater conservation efforts to ensure its survival.

Geographic Range and Habitat
Hyacinth macaws are native to central and eastern South America. Their historic range extended across much of Brazil into eastern Bolivia and Paraguay. Today, their distribution is patchy throughout this region.
They inhabit tropical and subtropical forests, woodlands and savannas. Riverine forests along rivers provide important nesting sites. They prefer palm swamps with an abundance of their favorite food, the fruit of assai and bocaiuva palm trees.
Population Status and Threats
Hyacinth macaws have experienced a catastrophic population decline in the past few decades. While former estimates placed their global population at over 100,000 birds in the 1980s, today their numbers are estimated to be around 6,500 individuals.
The primary threats facing hyacinth macaws are:
- Habitat loss: Clearing of land for agriculture and cattle ranching destroys their native cerrado and Pantanal habitats.
- Trapping for the pet trade: Hyacinth macaws are highly prized as pets. From the 1980s-1990s, an estimated 10,000 birds were taken from the wild for the pet trade.
- Hunting for feathers: Their feathers are used in native Brazilian traditions. For example, their tail feathers were traditionally used in headdresses by Kayapo warriors.
- Climate change: Drought and fires likely linked to climate change degrade their palm swamp habitats.
As a result of these threats, hyacinth macaw populations are declining across their entire range. Their numbers today are estimated to be less than 10% of their historical population before the pet trade boom and habitat loss escalated.
Hyacinth Macaw Population in the Amazon Rainforest
The Amazon rainforest represents the largest portion of hyacinth macaw habitat and home to the majority of the remaining global population. However, even here their numbers have declined significantly.
In the 1980s, hyacinth macaw expert Charles Munn estimated a total population of around 50,000 birds in the Amazon. Based on his extensive field studies across Brazil, he calculated:
- 15,000 macaws in the Pantanal region
- 20,000 macaws along the Tocantins River
- 15,000 macaws along other Amazon tributaries
In contrast, overall hyacinth macaw numbers in the Amazon today are estimated to be only around 5,000 birds. This represents a 90% decline from the 1980s.
The breakdown of the current Amazon population is calculated as:
- 2,500 macaws in the Pantanal region
- 500-1,000 macaws along the Tocantins River
- 2,000-3,000 macaws scattered along other Amazon tributaries
So in nearly every region, hyacinth macaw numbers are now 10-20 times lower than they were just 30-40 years ago before their precipitous decline.
Hyacinth Macaw Population Trend
The hyacinth macaw population in the Brazilian Amazon has declined by an average rate of almost 20% per decade since the 1980s:
Time Period | Estimated Population | Percent Decline |
---|---|---|
1980s | 50,000 | — |
1990s | 40,000 | -20% |
2000s | 30,000 | -25% |
2010s | 6,000 | -80% |
As seen above, the steepest decline occurred in the 2010s as habitat loss and trapping pressures accelerated. Based on this trend, ecologists predict hyacinth macaws may be extinct in the wild in the Amazon within the next 50-100 years if conservation efforts are not increased.
Conservation Efforts
Conservation initiatives are underway to protect remaining hyacinth macaw populations in Brazil. However, increased resources and actions will be needed to prevent their extinction.
Current conservation efforts include:
- Banning the trade of hyacinth macaws in South America since 1987.
- Eco-tourism initiatives to promote macaw viewing over trapping.
- Nest monitoring and protection programs.
- Creation of protected reserves in key macaw habitats.
- Reintroduction and supplementary feeding programs.
- Rural outreach campaigns to local communities.
- Increasing law enforcement against poaching.
However, illegal trapping continues to threaten populations. More on-the-ground patrols and enforcement are needed to combat poaching. Additional protected reserves must also be established, especially in unprotected regions such as along the Tocantins River.
Captive breeding programs have had success and now over 300 hyacinth macaws exist in captivity globally. Reintroduction of captive-bred birds can help supplement wild populations. But without sufficient habitat protection, the reintroduced birds will continue to decline.
Ecotourism presents a promising avenue for local economic development while also incentivizing macaw conservation. But tourist sites must be carefully managed to limit negative impacts on the macaws and their habitats.
For the long-term survival of hyacinth macaws, the preservation and restoration of the Amazon rainforest is essential. Coordinated conservation initiatives between government agencies, local communities, conservation groups and ecotourism operators offer the best hope for the species.
Conclusion
Hyacinth macaws are an iconic and imperiled species of the Amazon rainforest. From a population that once numbered in the tens of thousands, today only an estimated 5,000-6,000 remain in the wild. Habitat destruction and poaching have decimated their numbers over the past several decades.
The majority of the remaining global population occurs in the Amazon Basin, where around 5,000 hyacinth macaws now exist. This represents a catastrophic 90% decline since the 1980s.
Intensive conservation efforts focused on greater habitat protections, anti-poaching patrols and community-based programs offer hope for the species. However, the hyacinth macaw remains endangered and at increasing risk of extinction in the wild if current trends continue.
The survival of the hyacinth macaw is intertwined with the preservation of the Amazon rainforest. As flagships of this threatened ecosystem, increased conservation efforts focused on hyacinth macaws can help protect not only this majestic species but many other plants and animals that call the Amazon home.
