b. Pigeons to be used for signal communication should be trained with the message holder attached to the leg to accustom them to carrying it. Pigeons should be distributed to combat troops, with message holders attached if it is known that the receiving troops have not had training or experience in handling the birds. Otherwise, holders may be delivered separately. Personnel of a loft should make every effort to provide message center units being served with necessary information concerning care, handling, and release of birds.
Figure 23. Message Holder PG-67.
c. To remove a message from a pigeon, catch the bird after it has trapped; hold it in one hand, extend its leg, and remove the message holder with the other hand. Release pigeon in loft.
d. When it is necessary for a pigeon to carry a message and a message holder is not available, fold message blank, attach it by looping it around the leg band and tie its two ends together with a piece of thread or light weight string.
Caution: NEVER WIND a string or rubber band around a pigeon’s leg because it will stop the circulation and may cause the pigeon to lose its leg.
