The Zebra Finches seem to breed all year round, but we don't usually see them this small. The mother made a nest in a feeding basket (the white things are cuttlefish), so her babies were hatched out in the open instead of in their usual nestboxes.
The Ménage à trois canary family are busy. We have one male and two females, one of which has just hatched five babies. One baby fell out of the nest and didn't survive, but the other four appear to be doing well.
Ken finally put two nest boxes in the budgies' aviary, and they have been excitedly checking them out ever since. There are nine eggs in one, but we have no idea who the mother is, as several budgies go in and out of there all the time!
