The new society finches

I can't believe how fast birds develop! The babies first looked like tiny tiny frogs and now, after barely three weeks they resemble their parents already.
One day there was no tail, and another-pop!-there it is!
And I think both youngsters have their mothers funny crest and white a patch under the chin. 
You can see one baby sticking it's head out of the nest. The other one is stuck somewhere behind the parents. These babies do seep a lot. Just like all other newly-born.
