Channel-billed Cuckoos and Koels

Hi all heard my first CBC and Koel of the spring this morning. Perhaps not unusual for this time of year in Sydney except: a.. in my 18 years in Turramurra/North Turramurra, I have never had my first record of both on the same day (Koels normally, but not always, the first observed); b.. this is the earliest for both species, beating previous earliest returns by 2 days (CBC) and 10 days (Koel); and c.. both normally seem to show up in my neighbourhood about 12-14 days after the first reports arrive from elsewhere in Sydney – this year it was only 7 days or so. Waking to their early morning calling will now be a feature. Cheers Tom
