Chestnut-sided Warbler with Lunch

This little insect eating warbler must have been flying home with food for its young when I came along. Standing beside the river, within a stand of bushes and trees, I kept hearing a bird sound very loudly close beside me but I could not find its source. Stepping back to get a better view this little Chestnut-sided Warbler flew out of the tree that I had been standing beside.
