Today we attended the Avicultural Society birds sale in Warragul, which is about an hour's drive south east of Melbourne. Ken bought a pair of Gouldian Finches for $40, and a male Diamond Firetail Finch, which cost $50. He only bought the Diamond Firetail because it was a very good price (they are usually closer to $100), and we only had enough money between us for one! He has always loved these finches, but they are hard to come by, as they are an endangered species. He may buy a female at one of the bird sales later this year, but he will have to decide what to do with some of the birds he has at the moment, as they are not always compatible with other finches.
Our resident Gouldians seemed happy to have a new pair moving in with them. Ken will put another nest box in the aviary so the new ones will be able to lay eggs without disturbing the old ones nestbox.
I haven't got any photos yet, as it was raining when we got home - too wet and cold to mess about taking photos of excited/stressed little birds flying around like little rockets! Here is a photo of a Diamond Firetail, which I found on the website of the Australian Finch Society.
