PhysOrg Posted August 15, 2012 Share Posted August 15, 2012 (Phys.org) -- Researchers in Britain are confused by the mute swans of Abbotsbury Swannery. They lay four to ten eggs during a laying cycle which lasts generally a couple of days. During that time, they sometimes sit on the eggs laid up to that point, but not long enough to cause the eggs to begin incubation; that doesnt start until all of the eggs have been laid. So why do they bother at all beforehand? It seems like a waste of energy, which birds as a general rule, tend to avoid. Thats what this new research aims to find out. The group have taken a real egg, sawed off one end and fitted it inside with electronics embedded in rubbery silicon.
