Not too sure if this is the right place for this question but I'd like a little advice on my pending outdoor aviary. We live in a rural area away from everything, our house overlooks a small lake with two small islands on it. The water has goldfish and the islands have several trees for nesting and resting in. I thought of building an outdoor aviary at our house and letting the semi tamed birds out during the day to experience outdoor life for real. If these birds (possibly Lorikeets, Cockatoos, Galahs or other Australian ground parakeets) that are hand tamed and then allowed out to explore during the day, would they return at night to their home or not venture too far from home and start up at colony on and around our lake? We live in New Zealand with temperatures a little lower than Australia. The idea is to establish several colourful birds (we don't have them in NZ) that would continue to live here amongst the foliage but can return to a 'free to leave, or secure, aviary' if they want. Our native Tui and Wood Pigeon are becoming more prevalent here now possums and ferrets have become more controlled. Is this feasible?, to have aviary birds that will return home if they feel threatened? I'd love to look out my huge windowed area and see colourful and perhaps talking birds taking advantage of free flight, trees, water and also being able to fly to a safe haven when they feel threatened.
