The various books on Canberra’s birds are old enough that some record no breeding activity of Koels. The numbers and breeding activity of Koels in Canberra has clearly been increasing rapidly over the past decade or so.
Can someone point me to the most recent data that indicate the likely end-of-season timing? I still have Koels in my street in Deakin as of today (6 March). I would have thought that is rather late.
Other unusual observations for my GBS this week: 2 Noisy Friarbirds and one Grey Butcherbird. Yesterday (5 March) was a bit of an early Autumn bonanza with 16 species and something approaching 100 birds in a 20 minute peruse of the street
at about 8am – a good start to the post-leap day GBS record.
