sorry my mistake, upstream is south.


On reading through others emails and thinking about what I observed last friday and over the past 2 weeks (ie 4 times over 2 weeks), here is what I think is the most likely explanation.


A bird was sitting in the big dead tree ~500m North, downstream (East bank) from the old carpark. This bird looked to me like a black falcon, from the body shape, wings, sitting position, and lack of wing markings. It flew bye slowly along the stream upstream and off to the West out of view (~200-300m South or upstream from old car park).

A dollarbird flew from East to West over the river in the same place the falcon flew west and mobbed a bird which probably was actually a brown goshawk. This bird was mobbed for a fair while by the dollarbird and then it flew West to East quite fast (I assumed it was flying fast to avoid the dollarbird) and fed one fledgling and refused another, then flew off fast to the East. This bird appeared smaller, I thought at the time it was an optical effect of it flying lower. I did not get good views of this bird but could see it from behind. I could see it feeding the fledglings, within a tree, well refusing one. Begging has been coming from those trees over the past 2 weeks.


~2 Weeks before I saw a bird that I thought was a black falcon stand in the same dead tree then fly slowly south along the river then head west in ~ the same position as stated above. However, it turned back flying North along the West side of the ridgeline, along Gudgenby river (which I could just see through gaps in the ridge). It is possible the bird from last friday followed this same flight path and I wouldn't have seen it returning north as I was observing the dollarbird, goshawk etc.


So, I guess I conclude that most likely the begging and feeding was brown goshawks. But I also am sure there is another bird there, is it a black falcon? Or a brown falcon dark morph, or something else?


Tharwa BSI. If anyone happens to be heading down that way could they stop in Tharwa town. There is a bird there, that I think is a honeyeater. It calls with two slow high pitched notes woo wee, repeated 6 to 8 times. Then doesnt call for 10 minutes. It has really been bugging me, as I cant locate the bird after 6 visits there. I know I have heard the call before, but not very often, and am curious as to what it is.
