Finally there were two young birds that had incomplete RED crests. One had rather more red than the other. I conclude that these are juvenile or post-juvenile males, older than G4 and G5. That would give me the following tally of individuals in the tree during the day:
G1 – adult male; G2 – adult female; G3 – juvenile female; G4, G5 – juvenile males; G6, G7 – somewhat older males. If this was a GBS-type survey, I would not be able to put down 7 birds as I was not sure all were in the area at the one time. However I could nominate ‘4’, because G4, G4, G6, and G7 were all visible in the ironbark at the one time.
