I thought this message from Mark was interesting.  My direct answer to him was that I was not all certain but had assumed that by this stage of their life cycle all male birds would have acquired adult plumage.  According to HANZAB, "It ain't necessarily so"!
  • They fledge in juvenile plumage.
  • A moult into an immature plumage occurs within a few months of fledging. 
  • A first complete moult occurs at the end of their first year (or early in the second) which I would take to be about now;
  • Most males adopt adult plumage with this moult; but
  • Some only go into adult plumage with the second complete moult.
Thus it is possible that some of the brown birds around now haven't had their first complete moult while others are waiting for the second complete moult to get orange but are still interested in attracting mates and as Mark notes can breed if they get lucky.

Given that song has been going on continuously for about 3 weeks in the same areas, as David McDonald has suggested it would certainly meet the requirements for eBird breeding code T Territory held for 7+ days  which is rated as a Probable indicator of breeding.  This puts it above code C Courtship, Display or Copulation but below (ie less likely as an indicator) carrying nest material or nest building.

Are you sure your “singing female” was not an uncoloured male. From memory the pair that has bred at Campbell Park were “brown” birds. I don’t think that you can class the birds as breeding based on a song a it may just be a single bird in search of a mate.

I have previously commented on the appearance of Flame Robins in our area since the fires.  For the past couple of weeks - perhaps longer - they have been very vocal.  The song is that described on the Pizzey and Knight app as a Territorial song.  In most cases where I have been able to see the singer it has been a male bird.  However this morning I clearly saw a female giving the song without, as far as I could tell, a response from another bird.  It was possibly significant that a pair of Scarlet Robins were about 10m away.  


Reading the section in HANZAB seems to imply that the primary functions of these songs are establishing/defending a breeding territory (with Scarlet Robins being nominated competitors) and/or attracting a mate.  Am I thus justified in counting these songs as Display and thus breeding records?
