This species lives in the canopy of wet tropical forests and is highly dependent on the [[Dipteryx|almendro tree (''Dipteryx panamensis'')]].

In order to improve our knowledge on the ecology and natural history of this bird, a large radio telemetry was conducted by a team of researchers between 1994 and 2006. The main objectives of this study were to determine the home range of ''A. ambiguus,'' characterize the habitats that it frequents and learn more about its natural history in general (feeding habits, ecological associations, abundance, and reproduction and nesting habits).<ref name=":2" /> The results of this study were published in 2007. It was found that, in [[Costa Rica]] and adjacent [[Panama]], the habitats where great green macaws occur were dominated by the wood almond (''[[Dipteryx|Dipteryx panamensis]]'' [[Dipteryx|(or ''D. oleifera''))]]''[[Pentaclethra macroloba|,]]'' oilbean trees (''[[Pentaclethra macroloba]])'' and raffia palms ''[[Raffia palm|(Raphia spp.)]]''.<ref name=":3" /> This is not surprising considering that great green macaws depend on ''D. panamensis'' for both feeding and nesting.<ref name=":1" /> Another study published in 2007 revealed that the abundance of food within a habitat is not related to the abundance of macaw; however the researchers found that there was a link between the abundance of food and the amount of time great green macaws spend at one place.<ref>{{Cite journal|url = |title = Great Green Macaws and the annual cycle of their foodplants in Ecuador|last = Berg|first = Karl|date = 2007|journal = Journal of Field Ornithology|doi = |pmid = |access-date = |last2 = Socola|first2 = Jacqueline|last3 = Angel|first3 = Rafael}}</ref> == Behaviour == === Diet === The Buffon's macaw is known to feed on 37 species of trees, including the wood almendro ([[Dipteryx|Dipteryx panamensis]]), [[Sacoglottis|Sacoglottis trichogyna]], [[Vochysia|Vochysia ferruginea]] and monkey pot ([[Lecythis ampla]]), which composes most of its dietajor source of food.
