I noticed one of the diamonds was a "yellow", a bird with a yellow beak and tail. I remember someone posting about these recently. Aren't they rare or something?
anyway, they're not for sale I tried

but it will be interesting to see what happens if he fathers/mother a brood of chicks.
here are some pictures:
and here's a normal diamond for comparison. Other interesting events are:
a grenadier weaver hen with a very severely overgrown beak. it's eating fine (amazingly) but we can't catch it to help it.... and our resident pair of Pin-Tailed Whydahs - male at the bottom, not coloured yet but you can see the black in his wings
