Gliders (Stojanovic et al. 2017).
The prevalence of hollows in eucalypt forests and woodlands and close proximity to a foraging resource is considered more important than forest type and/or tree species in determining where Swift Parrot nests occur. Where suitable hollows are available, nest sites can be found in all topographic positions and aspects (Webb et al. 2012).
Swift Parrots reuse nesting sites and individual nest hollows over different years (Stojanovic et al. 2012) and this highlights the importance of nesting areas for the species' long-term viability. The presence of a foraging resource influences whether an area is suitable on a year-to-year basis (Webb et al. 2014).
Blue Gum and Black Gum forests and any other communities where Blue Gum or Black Gum is subdominant (e.g. wet eucalypt forests, dry eucalypt forests, forest remnants and paddock trees) are important foraging habitats (Webb et al. 2014; 2017). From one season to the next, Blue Gum or Black Gum may comprise the primary foraging resource. Planted Blue Gums (e.g. street and plantation trees) may provide a temporary local food resource in some years, noting that plantation Blue Gum are unlikely to provide substantial forage resources due to age, tree density and genetic strain (FPA 2014).
Generally, the larger the tree the more foraging value it has for Swift Parrots. Brereton et al. (2004) demonstrated a greater flowering frequency and intensity in larger Blue Gums and a preference by Swift Parrots to forage in these larger trees. During the breeding season, Swift Parrots often feed on lerps, wild fruits such as Native Cherry (Exocarpos cupressiformis) and the seeds of introduced eucalypts and callistemon species. The relative importance of these other food sources during the breeding season is not well understood.
Non-breeding dispersal and post-breeding habitat can be anywhere in Tasmania, including forests in the west and north-west. The species has been observed feeding on flowering Stringybark, Gum-topped Stringybark, White Gum, Mountain Gum (E. dalrympleana), Cabbage Gum (E. pauciflora) and Smithton Peppermint (E. nitida) (Swift Parrot Recovery Team 2001).

1.6                 Breeding biology
Birds arrive in Tasmania in early August and breeding occurs between September and January. Both sexes search for suitable nest hollows, which begins soon after birds arrive in Tasmania. Nesting commences in late September, however but birds that are unpaired on arrival in Tasmania may not begin nesting until November, after they have found mates (Brown 1989). Gregarious by nature, pairs may nest in close proximity to each other and even in the same tree (Stojanovic et al. 2012; Webb et al. 2012).
The female occupies the nest chamber for several weeks before egg laying and she undertakes all of the incubation and brooding until nestlings are sufficiently developed. The mean clutch
