My impression is that other cuckoo species (out in Carwoola Fan-tailed and Pallid) are also vocalising much more than is usal for this time of year. On the subject of Koels Nick Nicholls has pointed out a really stupid error in my column in Gang-gang for February. I said "In both cases the tendency is towards “later”: come later, leave later." In fact the graph and the data shows that the tendency is to come EARLIER. With sequential week 1 beginning on 3 July, the first koels arrived around sequential week 20 (mid-November) in Year 15 and now turn up around sequential week 15 (mid October) This actually reinforces the more significant trend of them being observed for longre!. I apologise for this daft error and thank Nick for pointing it out. Martin On Fri, Feb 25, 2011 at 6:46 PM, Michael and Janette Lenz <> wrote:
