Ive had a pair of cockatiels (Male and Female) for 3 monthes. They are about 1 year old now and im afraid that ill never be able to train them. In the past 3 months ive made hardly any progress ( besides being able to get the female on my finger every now and then. The male is constantly making a warbling like sound, and hes still as afraid of me as when i first adopted them. Some advice would be apreciated. Its starting to get a bit stressful.
