SPCA Otago executive officer Sophie McSkimming said rescued birds taken to Otago SPCA were housed in an old cattery.
The ''makeshift'' aviary had been ''tidied up'' by the ''periodic detention boys'' yesterday but the bird house looked ''bedraggled'', Ms Skimming said.
The aviary had limited creature comforts for the chickens, gulls, geese, ducklings and ''odd canary'' that had been housed at the animal shelter.
But the birds could expect an upgrade, after infrastructure company Delta donated $5000, which Otago SPCA would use to build a new aviary in the spring, she said.
The new aviary would be built on the ''old Dunedin City Council dog pound site'' at Otago SPCA in Opoho, Ms McSkimming said.
SPCA Otago animal manager Grace Hepburn said the new aviary would have stands for birds to perch on and boxes for the birds to sleep in.
Ms Hepburn said it would be more hygienic and easier to clean. Delta's chief executive, Grady Cameron, said thefundraiser was part of a Delta safety campaign.
When Delta staff submitted a ''close call'' or ''new hazard'' report, money was deposited in a charity fund.
Delta greenspace services team leader Robert Bayne said he reported a faulty hedge-cutter and was selected to choose the charity.
