I feel that the question about
Am I thus justified in counting these songs as Display and thus breeding records?
is that display and or singing probably are signs of an interest (in those species) and worth noting but they are only of peripheral value as a breeding record in establishing
a time line, if followed up by more specific evidence of breeding at the same site (usually later). Lots show a sex or territory interest without actual breeding...... Some species sing or display at any time of year. Which is why di & co are the last breeding
options listed on the GBS chart. What I suggest is once you have a date of a nest etc, then backdate the dates of “display” into the record....... Just my opinion, although the listing on the GBS chart sorts of formalises it. .

Perhaps, Martin, it warrants the eBird breeding behaviour code 'T': 'Territory held for 7+ days (Probable) -- Territorial behavior or singing male present at the same location 7+ days apart.'
Jaron could advise how eBird's 'T' code maps to COG's breeding behaviour codes, but I imagine that DI would be the one.

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?
