The Dickin Medal
The Dickin Medal, instituted by Mrs Maria Dickin, founder of the People’s Dispensary for Sick Animals in England, was popularly referred to as "the animals’ VC". It was awarded to any animal displaying conspicuous gallantry and devotion to duty associated with, or under the control of, any branch of the Armed Forces or Civil Defence units during World War II and its aftermath.
At least two Australian carrier pigeons attached to the Australian Army have received the Dickin Medal:

Blue Bar Cock No. 139:D/D:43:T
Detachment 10 Pigeon Section (Type B) attached to Detachment 55 Port Craft Company, Madang 12 July 1945. Awarded the Dickin Medal for gallantry carrying a message through a severe tropical storm thereby bringing help to an army boat with a vital cargo, in danger of foundering.
This pigeon was donated to the army in 1943, as a patriotic gesture by a civilian pigeon fancier, Mr George Adams of 11 Vigo Street, Footscray, Victoria, for use in signals units in New Guinea. Mr Adams, however, was not the bird's breeder. As part of his effort to obtain birds for the war effort Adams approached members of pigeon clubs in the Melbourne area, seeking the donation of birds. After he had approached the Yarraville Pigeon Club, one of its members, Mr Gordon Whittle, whose family had bred and raced pigeons for many years, donated a number of birds. One of the pigeons he bred was awarded the Dickin Medal for gallantry as a result of a flight he undertook through a severe tropical storm near Madang, New Guinea, on 12 July 1945. At the time the pigeon was located at 10 Pigeon Section (Type B) attached to Detachment 55 Port Craft Company, Madang. On that day he carried the following message, from a foundering boat to Madang, flying 40 miles in 50 minutes: 'To: Detachment 55 Australian Port Craft Company, MADANG. From: A.B. 1402. Date: 12.7.45. Engine Failed. Wash on to beach at WADAU owing very heavy seas. Send help immediately. Am rapidly filling with sand. TOO: 0800 - Senders signature - HOLLAND Cpl. TO Liberation 0805 - No. of copies 2. TOR at Loft - 0855'. As a result of the successful delivery of the message the boat together with valuable stores, ammunition and equipment was salvaged. The bird had previously completed 23 operational flight over a total distance of 1,004 miles.
