Wild Rhea Welfare: South America Flightless Birds

Greater and lesser rheas face welfare threats from habitat loss, egg collection, hunting for feathers and meat, and capture for the exotic pet trade across their South American range.

Key Facts

Greater rheas are the largest birds in the Americas and can run at up to 60 kilometers per hour
Rhea populations have declined significantly from hunting and habitat conversion to agriculture
Eggs are collected from wild nests, removing breeding opportunities from wild populations
Rheas are sometimes captured for farming or the exotic pet trade, causing stress during capture and captivity
Male rheas incubate all eggs and raise chicks alone — disrupting males removes care for entire clutches
Rheas play an important role in seed dispersal in grassland and Cerrado ecosystems

Welfare Considerations

Rhea welfare in the wild is threatened by the conversion of South American grasslands to intensive agriculture, which removes both habitat and the open foraging areas these birds depend on. Hunting for feathers used in decorative items and for meat imposes direct mortality, while egg collection removes future generations. Capture for captive farming or the pet trade is acutely stressful for animals adapted to open-range running behavior. The paternal care system means that disruption of a single male affects an entire cohort of chicks. Conservation of Pampas and Cerrado habitat is the most effective welfare intervention for wild rheas.

What You Can Do

Support conservation organizations protecting South American grassland and Cerrado habitats for rheas
Never purchase rhea feathers, eggs, or products from wild-caught rheas
Advocate for stronger protection of rhea nesting sites during breeding season
Support sustainable land use practices in rhea range that preserve open grassland habitat
Donate to monitoring programs tracking rhea populations and habitat quality
