Thanks for that. So mainly a warm month visitor. (The first RAOU Atlas suggests that too, the second RAOU Atlas is hard to perceive any trend). So is the current winter record record unusual? It does beg the question though about counting the number of records by month. Are these separate records? How real are these data in terms of the species presence? In this species I perceive that there would be very few separate events. The species is rarely here and when here many people go to find it. So there may well be a lot of recounting of the same birds in this graph. Which can make a trend look bigger than it should.

Previous records of Australian Little Bittern are all from October to March. The graph below shows the number of records by month for the period 1 July 1981 to 30 June 2013.
