[below: Scrub Turkeys were a common sight at Lamington]
What happens is the male turkey scratches up leaf litter and soil into a mound - about 6 foot (2m) across and 3 foot (1m) high. A hole is made in the mound in which the egg is laid. The mould must be damp otherwise not enough heat is generated to hatch the eggs.
Amazingly, the male turkey has very accurate heat sensor inside his upper bill and regularly checks the mound temperature by sampling the leaf litter. By adding or removing litter he can keep the nest at a constant temperature of 33 degrees C. Clever, hey? Well, that's not all.
And after all this trouble to ensure that the eggs hatch - guess what happens next?:
Yes, once the chicks are hatched, the scrub turkey parents feel that they've done their bit, and leave their offspring to make a go of it as they will. Modern progressive thinking! I feel that there is something here which all parents should seriously consider....
