This thread is interesting as on Monday and Wednesday up to twenty Top Knots
were observed at Cape Hawke, Forster. I have never noticed such numbers at
this area before however I had not been bird-watching here too many times.
Is this just observer bias or is there some other reason such as movement
from Coastal ranges to the coastal lowlands, or a very good breeding season?
