The creature make a grunting sound and also a screeching noise when disturbed. he said.
Mr Gilroy said these characteristics are identical with those reported by American researchers of bigfoot - in Canada and the United States, as well as the legendary abominable snowman of the Himalayas.
Mr Gilroy believes the Yowie is a surviving remnant of a pre-ice age man-like ape fauna, of which the abominable snowman and American bigfoot are also surviving relatives'. The creature would have spread out from Asia over land-bridges which once linked Australia and America to the Asian mainland," he added.
During his forth coming search. Mr Gilroy will inspect plaster casts of enormous ape-like footprints. The original footprints were discovered recently near Scone in the same area where an enormous hairy ape-like animal was reported seen by a bushwalker.
"The site is situated in a region of the densely wooded Barringtod Tops where sightings of
enormous hairy ape-like-man-like beasts date back as early as 1842 and 1848 when the creatures
were first reported seen by early settlers in the Carey's Peak district, Mr Gilroy said.
MR Rex Gilroy, the naturalist who believes that a relative of the Himalayan abominable snowman inhabits Australia. Mr Gilroy will also investigate reported sightings of the mystery creatures at Maitland,
Taree, Kempsey, Grafton and Lismore.
He has launched an appeal among residents of these
districts who may have information helpful to his investigations to contact him. A similar appeal launched by Mr Gilroy recently in southern NSW resulted in several dozen fresh reports of
Yowie activity in the ACT (in the Tidhinbilia area)Bega and the Australian Alps.
"The Yowie is no stranger to the Mount Kosciusko district where the creatures have been
known since the 1860's. A group of skiers sighted an enormous hairy man like animal moving
through snow up a mountainside thereabouts during July 1975," he said.
The creatures, do not aways keep to themselves. In 1969. two wild life rangers and a group of timber cutters saw a group of five 5 smallish ape-like animals moving through dense rainforest scrub on the Atherton Tableland near Cairns.
