Significant sighting

3 Mar 2022

Great head shot photos = throwing light on the movement of Rex an Goanna that has bene monitored since 2015 - If you happen to come across a Goanna please try to get images of both sides of the head

Lovely face photo Trevsci! Annnnd (drum roll), this is Rex, first photographed by Matt Higgins in 2015. He mated with Rosie who produced offspring two years running. All previous sightings of Rex have been almost 4 km further south on the north west aspect of Mt Ainslie. Male home ranges are generally around 2/3 of a square kilometre (66 ha) so this location near the old Majura Horse Paddock indicates he may be on some kind of excursion out of his home range. But we have previously seen those sorts of movements only at mating time (Dec-Jan) and in March-April when they move to winter quarters.

That's cool thanks for the details Don

Don is there any significance that Rex is just beginning to shed his old skin? Does it mark a change in season?

Not as far as I know Michael. Patches come loose throughout the warmer months and when they are growing rapidly.

So interesting, well spotted and photographed Trevsci.
So either his home range is larger than expected or he is looking for adventure or new real estate.
If the latter, perhaps the human and dog population has driven him and/or his partners away from their base on Mt Ainslie - they did once occupy Black Mountain. Sad if that is the case.

if you look close the Rm on the feature image has a bite mark at the base of its tail. Unfortunately, people walking their dogs off lead increased during Covid19 and it didn't help that Parks Service ranger positions were culled. Our nature reserves are clearly not managed for their conservation values...
