Chaffinch song sequences, 28 April

Listen to the sequences

I apologise if you have a problem accessing the sound clip when using Internet Explorer - I hope to find a solution to the problem soon. I have tested the page successfully on an iPhone belonging to one of my sons, and at home on three computers (running Windows XP, Vista and Win 7 - 64bit), using Firefox and Internet explorer, but while it works every time when using Firefox, on the Vista computer IE 9 doesn't like the embed command that I've used.
