Subject: Greenfinch ‘visibility’ and calling season

Hi birders

Making one of my infrequent intrusions into the conversation …

The last few years I’ve noticed that Greenfinches start singing quite late in the season, after at least one breeding round is over – possibly all breeding concluded for the season. In the fortnight before Christmas and into about the second week of January, singing male Greenfiches are prominent in parts of the Macedon Ranges (Central Victorian Uplands) where I live, and around Melton (lowland volcanic plain, western edge of Melbourne). They’re nearly invisible when not calling in these lower density populations.

Why do they start calling so late? Apparently in their native range in Europe they start calling very early in Spring, but I haven’t noticed that here in Victoria.

cheers
