Goldcrest song

Can you hear Goldcrest song?
I am following up Richard Porter’s comments in British Birds 105(3):152 and gathering data on the age-related loss in the ability to hear Goldcrest song. I have close to 300 responses so far but need more data to fill in gaps in the data.
Please help: I need just your gender, age and whether or not you can hear Goldcrest song. You can let me know to [email protected] or if you prefer to Oakerley, Clun Road, Aston on Clun, Shropshire SY7 8EW. Thank you.
I try to reply personally to every submission but if I receive too many replies to this, being sent to every county in Britain, I may not be able to keep up so my apologies now if I don’t get back to you with thanks.
The results will appear later this year in British Birds and online at John Tucker,
