Descriptions of a portable egg candler, an egg volumeter, and the technique of photographing incubated eggs with transmitted light have been presented elsewhere (Hanson, 1954, Journ. Wildl.

These photographs should also be useful in determining the stage of development of eggs of other species whose incubation periods are similar. Photographs
