masses on detail on life span, weights, etc.;
‘range-map’ – habitats of the sub-species (surprises here);
diseases;
significant detail on the size and nature of pens; capture, handling, and transport (times of day, temperature concerns, long and short trips);
sedation; huge section on routine health checks and diseases;
reproductive problems – femaies need calcium!;
individual and social habits – emus will walk 600 miles in a season;

And lots lots more
