Fairy-Wrens feeding a family

On a recent trip to Mt. Tomah in the Blue Mountains I witnessed a pair of Superb Fairy-Wrens feeding a family of chicks. I was amazed at the constant activity and the speed at which each bird left the nest, only to return with more food a few moments later, feed the chicks, and then head off again. I could not see the nest as it was buried deep in a dense bush and I did not want to cause undue stress to the parents by getting too close.
