5 birds. Perhaps going to settle in and roost? Then disturbed by Western Raven and flew north possibly to the northern reserve of Narrikup.
A group of around 10 birds possibly Carnaby's? feeding on ??? on the road verge.
Other white-tailed bc's were feeding on Marri honky nuts closeby of which some were definitely Baudin's. Calls of whicher whicher were also heard.
A few marri honky nuts were picked up which showed markings from both white-tailed species.
Photos aren't the best so I doubt an exact ID can be made.
