Frequent stress can eventually weaken a birds resistance to disease. Gouldian finches must be kept at a temperature of approximately 70 degrees or more fahrenheit. Different authors stress that the humidity level should be maintained at or above 50 percent. Breeding activities may require higher levels of humidity. These publications recommend the use of a humidifer to increase humidity.
Moisture released by large potted plants can also be helpful.
Interestingly, some gouldian finch breeders argue that humidity is not that big a factor. The editor suggests increasing humidity, as one possible solution, if difficulty is experienced getting gouldians to breed. Cold or drafty locations should be avoided. Gouldians need natural sunlight as well as shade. Its housing should allow the birds access to natural sunlight.
