Feathered bums lived here.......

My wife snapped this shot, but I love the construction of nest that it has to be the Blip of the day.

The nest held four youngsters, which played dead whenever we peeked in on them in the bush where the nest was built. We believe they've all fledged successfully.

I'm amazed at the construction of the nest. I couldn't do it with two hands, so how does a Blackbird do it with a beak and a bum?
