This individual is likely to be the male seen in the breeding episode posted to the Atlas a couple of days ago. This conclusion is based on facial markings. We were alerted to the presence of the monitor once again by Kookaburra alarm calls. The monitor was high in the tree sunning itself; the position was good for north-west afternoon sun exposure on a cloudy/smoky day and the monitor’s abdomen was widely spread to maximise exposure in the typical fashion.
It's good that you can recognise individuals by facial markings, as it adds meaning to behavioural observations, social interactions, notes on territorial disputes and may even give an indication of home ranges etc. It's a valuable field tool.
