Caroline aan de Wiel gave a paper at the Celtic Congress in Cork 99 where she argued convincingly that the wren 
actually IS the druid-bird, and that the two words in various Celtic languages are identical.

By coincidence we were reading a passage of the Mabinogi "Math uab Mathonwy" in a Middle Welsh class the other 
day where it was related that Aranrhod's nameless son skillfully hit a dryw = wren with a stone between the sinew of its 
leg and the bone (58, 22 ff. in Mühlhausens edition of the Mabinogion). This incident led Aranrhod to call her son Lleu 
Llaw Gyffes (= Lugus of the Skilled Hand) against her will.
