A BIG thank you Rox !
From my observations, I think that one of my now four cuties, is a boy (maybe

). If they'd only sit still long enough, and oblige me by bending over while facing away from me, I could be more certain, but alas they are not in a cooperative frame of mind most of the time, lol.
I'd even tried tossing meal worms into the flight to get them to er... look downward from the branches (the logic being, that I could then get a good look at their bottoms), but it became a feeding frenzy, and I gave up
Have you ever seen waxbills playing tug of war with worms? It was rather funny (not for the worm I'm sure) in a gruesome sort of way, blehhh.
