Unfortunately it's been raining and the wren is hiding. No opportunity to wander round the garden either. Nevertheless, some words have been bouncing around:
some say the robin is a sweeter tweeter
but the wren is the doyen of sound/song
the round ....something... of feathers
like a little bomb of song / notes / sound
Perhaps doyen is too grown up for this age group. Perhaps the odd ununusal word is OK. Playing around with the sounds and swapping words about - I could do with some fridge magnets. No, REAL ones!
