Wren & Eurasion Treecreeper, Hodbarrow RSPB reserve, Cumbria, UK (Troglodytes troglodytes & Certhia familiaris)

This Treecreeper was being accompanied through some scrubby woodland by a Wren. Someone in my local birding group suggested that maybe the Wren was hoping to take advantage of insects disturbed by the Treecreeper. It's a nice idea. The Wren certainly seemed to be following the Treecreeper around.
