Songs for percussion

I have been writing more percussion music recently. Over a year ago I wrote a short piece for solo percussion based on  the robin's song (Erithacus rubecula). To see a world... comes from a famous poem by William Blake Auguries of Innocence. 

To see a World in a Grain of Sand 
And a Heaven in a Wild Flower, 
Hold Infinity in the palm of your hand 
 And Eternity in an hour.

The poem goes on to say: 'A Robin Redbreast in a Cage \ Puts all Heaven in a Rage.' The success of this piece inspired a more recent suite for percussion ensemble based on Australian bird songs, and I may add more European birds to make extend the idea.
