It seems the references to Pigeons being used in the Services are back in the news again!
A dead Pigeon skeleton has turned up in a chimney with a canister attached, with a coded Signal inside, which currently nobody can crack!
GCHQ today - "Please bear in mind though, as indicated in our press release:
http://www.gchq.gov.uk/Press/Pages/Pigeon-takes-secret-message-to-the-grave.aspx that without access to the original cryptographic material, or context around the messages, we are not able to decode the message, this means that it is also virtually impossible to verify any suggested solutions."
"Should you want to pursue your interest in this story, or the World War Two pigeon service, we recommend that you contact or visit Bletchley Park, where there is a Pigeons at War exhibition:

Perhaps Bletchley Park may know how frequent Pigeon use was?
