There is a pargraph in the "Rebels: The Irish Rising of 1916" on page 324. It is under Tuesday (of the Rising). It tells of Countess Markiewicz, who is on the roof of the Shelbourne Hotel, when she sees a man holding a brown bag above his head and she stops the shooting. It is James Kearney, the parks keeper, who feeds the ducks. They did this twice each day of the Rising. It is a little levity during a time of war.
The surname intrigues me, as I have Kearneys in my ancestry. Long live the ducks!
