  Heron - Wikipedia, the free encyclopedia
The herons are wading birds in the Ardeidae family.
The classification of the individual heron species is fraught with difficulty, and there is still no clear consensus about the correct placement of many species into either of the two major genera, Ardea and Egretta.
Although herons resemble birds in some other families, such as the storks, ibises and spoonbills, they differ from these in flying with their necks retracted, not outstretched.

 Heron of Alexandria, Inventions, Biography, Science (1/2)
Heron from Alexandria (Heron Alexandrinus) was a Mathematician, Physicist and Engineer who lived in 10-70 AD but some references consider also 150 AD which is probably wrong, as in one of his works he referred to a recent eclipse which is now thought to have occurred in 13 March 62 AD.
Technically speaking, Heron's clever inventions were particularly notable for their incorporation of the sorts of self-regulating feedback control systems that form the bedrock of cybernetics; like today's toilets, his "inexhaustible goblet" regulated its own level with a floating mechanism.
Heron describes constructions similar to the Theodolit used for measurements of angles and other devices such as the odometer used to measure distances.

 Walkabout - Heron Island
Located 72 km northeast of Gladstone and 539 km north of Brisbane, Heron Island is a small coral cay which is part of the Great Barrier Reef.
It wasn't until January 12, 1843 that the HMS Fly anchored off the island and the ship's naturalist, Joseph Bette Jukes, noting the reef herons, named it after the herons which are part of the rich bird life which inhabits the island.
Because there is a deep sea channel between Heron Island and Wistari reef the ability to explore the edge of the cay, while remaining in calm waters, is unequalled.
