Willow Warbler?

We have been watching a Willow Warbler doing similar antics this afternoon on a local reserve. I was flitting in front of us along the path and jumping up to the vegetation and down again. When we looked at the vegetation there were a number of small caterpillars under the leaves so we decided that the bird was feeding on them. Further down the path both a Blackbird and Song Thrush were feeding on Toadlets that were hopping over the path. It must have been the day for different diets for the birds
