I have replaced "microdot" with "microfilm image", since our Microdot article does not support the existence of the technology prior to WWII. Sharkford 20:43, 19 October 2006 (UTC)
Partial Carrier pigeon merge
The war-related material at Carrier pigeon is proposed to merge into this article (if any of it needs to be retained), with the remainder merging to Homing pigeon, to which the emptied article title would redirect, and to Pigeon post. The merge of all of those (before War pigeon was created) was first proposed (at Talk:Carrier pigeon) in September 2009 and was unopposed, but did not get performed.
