We describe a system for photographing the longitudinal and transverse planes of bird eggs that improves accuracy of measurements of egg size and increases the speed of data collection. The proposed system consists of a flat support, with a few small holes where eggs are lodged. The system was tested using Japenese Quail (Coturnix coturnix) eggs, and the accuracy and repeatability of the photographic method were high.
