The parrot is frequently observed at lake reserves in suburban areas on the Swan Coastal Plain, within sight of waders (Charadriiformes) occurring at freshwater to brackish wetlands. It is common at the Forrestdale and Thomsons Lakes Ramsar Site, Bibra Lake, and the Benger Swamp wetland, a region rich in avian species. It is also found at the Dryandra Woodland, another species-rich reserve with the stands of jarrah and marri over sheoak (Allocasuarina huegeliana) and dryandra (Banksia ser. Dryandra) that are known to be favoured. Red-cap parrot is commonly sighted at Two Peoples Bay Nature Reserve and along roadsides around the Stirling Range and Porongorups.
