I wonder about the idea of time of day of their activity. Not saying I know at all. However is it possible that the “generally considered nocturnal” is given as sort of excuse? Given that they are so hard to find in the daytime (mainly because of their habitat), that therefore they suggested as are active at night. But then they clearly are seen active in the day. How would anyone see them at night anyway, to know that they are being active? I have only seen them in the daytime but not tried at night. And that is not a lot and probably same for most others. Another observation is in the times I have travelled past marshland in the Philippines, there appear to be many bitterns of a range of similar (or the same?) species. Though not easy to identify. As in in open wet lands, they are the common birds that are easily seen whilst travelling around by car or bus (or walking) during the day although I think slightly more at dawn and dusk, you see many of them flying around. So are certainly active during the day. Maybe they also fly at night or more of them but I did not get that impression and it is hard to see them then.

Thanks all. The two hours from sunrise this morning showed Jerra Wetlands in all its beauty, even though the bittern did not appear – probably catching up on the literature on how it was supposed toi behave!

Re “Mainly crepuscular and nocturnal”, this may not be the case. I am aware of many observations of them actively feeding during the day (including those made personally). When the South African representative was studied more closely it turned out to be mainly diurnal.  From the discussion in my article on the Australian Little Bittern in CBN Vol 38 No 2:

There are varying views on when ALB is active. Some examples are:

· McKilligan (2005)- “usually forages alone at night or at dusk and dawn”.

· Marchant and Higgins (1990) - “Active day and night, especially early morning and evening”, “generally considered nocturnal but, when breeding, seen flying over reed beds”.

· Birdlife Australia’s web site on the Bittern Project page does not indicate when the bird is active.

· Serventy (1985) – “Diurnal or nocturnal (evidence conflicting)”

It’s not really my story to tell, Steve, but I’ve seen the male once from the Bittern hide where I believe most of the VERY INTERMITTENT AND FLEETING sightings have been.  Shorty saw a juv from Cygnus.  As to time, take as a starting point HANZAB:  ‘Mainly crepuscular and nocturnal …’


Among those not having the best of years so far:  Australian cricket followers, gardeners, beetle-eating bird species, US govt workers, polar bears.

Having just returned to Canberra after eight days in the Victorian forests without email or internet, I haven’t read all the chatline emails or eBIrd entries about our Little Bittern(s). Can someone please enlighten me as to which hide at the Jerra Wetlands, and which hour of the day, provide the highest viewing probability?


Happy New Year to everyone, by the way
