Bird Rings

I found a dead chaffinch on my lawn this afternoon.

It had been ringed and the ring read:

NH Museum

London SW7

Y 126154

So I suppose my questions are:

Who ringed it?

What do the numbers mean?

Does my reporting this interest anybody at NHM?

    The purpose of ringing is to see how far birds travel and how long they live, amongst other things. The only way to find this out is when the finder of the ring reports it.


    Who ringed it? A bird ringer working through the British trust for ornithology

    What do the numbers mean? NH Museum, London, SW7. is the address you send the finding information to

         Y 126154 is the unique number for that bird

    Is any any one interested, yes they certainly are, and so are you! The main research body is the British Trust for Ornithology (BTO). I think I am right in thinking that the NHM address is used because it has and never will move, so a ring found in fifty year has a valid address on it and it fits on the tiny ring!


    Send a letter to the address stating; the place and date found and what condition the bird was in (fresh, decaying, skeleton) and if iyou can tell how it may have died (was it on the road side?, was there a sparrowhawk standing over it!!?) Include your name and address and you will be sent a letter back including exactly when and where the bird was rung and who the ringer was.

    Although birds ringed in Britain wear rings with our name on them, the Natural History Museum does not coordinate this activity. It is done by the BTO (the British Trust for Ornithology). Here is a link to their web page:

    You can report your find at or call them on 01842 75 00 50.
