I like Ripley's idea of rotating flowering shrubs. If I hear correctly it sounds like he'll have a whole bunch of mini shrubs in a greenhouse and he'll be able to trick them into flowering all year round. My understanding of wild scarlet honeyeaters is that they follow the flowering shrubs, so this idea should be spot on.
A few thoughts on the issue based on my experience albeit with non-softbills.
1. Most species will breed better as a single pair in their own personal aviary.
2. The smaller the aviary the easier it is to control the environment in terms of temperature, rain, predators and disease.
3. Watching birds in small aviaries (or worse still cabinets) is boring as they can't express their full range of behaviours.
4. If a pair of birds in a suspended aviary is breeding does that imply they are happy? Maybe, Yes, No - I'm unsure of the answer.
5. The purpose of suspended aviaries is to keep the crap away from the birds. A single pair of scarlet honeyeaters is hardly going to generate much crap.
Putting all that together means....
Maybe small conventional aviaries and by small I’m thinking about 3m X 1m for each pair. Would that work?
Ripley can then sip his scotch whilst watching and breeding scarlets, and growing and rotating flowering bonsai till his heart's content!
