The study also examines the role of both .endangered macaw species in the dispersal of large seeds. This role is largely due to the now-extinct megafauna, which inhabited South America during Pleistocene Epoch, which lasted approximately 2.5 million to 12,000 years ago.

Fernando Hiraldo from Spain’s Donana Biological

Station was co-author of the study. Are Bats Birds He said that the findings clearly show that large seeds were once the exclusive domain of larger animals. Herald stated that they can do this over great distances which is very important for dispersed plants’ genetic health. It is incredible how they can transport multiple large fruits over long distances using their claws or mouths.

He stated that the study also shows the success of dispersal as evidenced by the numerous plant germinations found beneath the trees where the macaws took their fruit. The study warns that a continuing decline in the number of macaw species and shrinking habitats could compromise the dispersal of large palm trees. This study emphasizes the importance of plans to protect both species and restore ecological functions in their habitats.

Conservation and threats

Jose Antonio Diaz Luque, another co-author of the study and director of the Foundation for the Research and Conservation of Bolivian Parrots, stated that the “declination of these macaw populations ends up affecting the habitat’s structure and the ability for regeneration.”

On the IUCN Red List, the hyacinth Macaw has been classified as vulnerable while Lear’s Macaw is endangered. Both species have seen dramatic population declines and decreased range in recent decades. An estimated 6,500 Hyacinth Macaws remain wild in isolated populations throughout the Amazon, Cerrado, and Pantanal. There is likely very little or no genetic exchange between them.

Fewer Lear’s macaws are found, with just

about 1,200 within 50 km (30 miles) of each other.  Crested Birds They once roamed over 845,000km2 (325,000 mi2) in Caatinga. Caatinga has been severely deforested due to the expansion of livestock pastures. This has had an adverse effect on the regeneration of the Syagrus coronata lecture palm, which is the main food source of Lear’s macaw. 

The preservation and regeneration of the lecture palm have been the focus of conservation efforts to save the macaw. According to the study, the Pantanal and Cerrado are suffering from rapid deforestation due to the expansion of livestock pasture and farmland.
