I have a question re portion control of supplied nectar mix. As far as I can tell, I should be providing around 5-10ml per bird per day. That's not a lot of nectar mix in a bowl, even one as little as 150ml (which I can't even see the birds landing on the edge of all that well).
I haven't ever given nectar mix to the chats, just had copious amounts of sugar in the home made cake (which is consumed very readily). On that basis, I presume I could also add small amounts of the nectar mix the same way for them but they are very active and healthy on their current diet so I haven't bought it for them as yet.
What's the easiest way to supply nectar to the silvereyes (and one day the honeyeaters)? I get adding it to cake or live food but do they need to think they are "drinking" it?
How long will the mix last made up but not frozen? (Could I, for example just put it in one of those tube feeders with a spout at the bottom and replenish every couple of days in winter and daily in summer or does it need to be replaced every few hours in summer?).
Made up at the recommended rate (wombaroo is 300g / litre of water which is 30g per 100ml) is it basically paste / damp crumble or is it more liquid than solid?
The flight I'm thinking of for the silvereyes is 2.8m x 1.2m. It is fully roofed and will be "planted" across the back third with plants in pots that can be rotated. They'll share the flight with 1 pair of longtails and 2 pairs of redbrows. In time it will be merged with the identical flight beside it (making it 2.4 x 2.8m) and more heavily planted to bring in the honeyeaters (recognising the redbrows may need to move out then).
