are Double-barred Finches declining in the ACT?

[Martin Butterfield <>]

I have consulted my records for Carwoola, and they also show a recent decline.  

As the years of higher reporting levels seemed to coincide with higher rainfall I checked the level of correlation between the two series.  That gcve a value of r of 0.59 which indicates a +ve relationship but not a strong one.  

Perhaps the finches will recover when/if this appalling drought concludes.

Having just drafted the text for this species for the forthcoming Annual Bird Report I can make the general comment that the statistics back up these anecdotal observations. In particular the abundance and reporting rate metrics are down significantly on the 30 year average for both general records and Garden Bird Survey records.

This is a sp I used to see quite a bit without looking for it, but recently I realise I have rarely seen them. I continue to see Red-browed Firetails commonly and Diamond Firetails uncommonly.
