Hi All,

I have been flat strap since getting back last Saturday after watching the 
total eclipse - hence this is the first time I have read the thread about what 
the birds did.

We watched it from near Mt Molloy and had an uninterrupted view.  It was the 
most magical thing I have ever seen! In response to Phil Veerman's email I 
decided to try and get a recording, but I did not want to have to think about 
being distracted from such a visual event.

When we finally drove out of clouds to a spot where the sun was in full view 
near Rifle Creek I noticed a track leading off the layby where we parked.  I 
walked down the track at high speed to put my olympus recorder and microphone 
far enough away from hollering, yelling humans (me among them, of course!) - 
but near enough to allow me to be able to identify the exact time of totality.  

So I have a recording from about 0615 to 10 minutes after totality.

I have listened to it once since and have not downloaded it yet. Once I do 
download it and work out the timings correctly I will be more than happy to 
share it with anyone with an interest or bent in analysing this sort of thing.

Understand, though, that I am a real novice at this, and so I cannot vouch for 
how useful it will be, and, as mentioned you can hear some human responses and 
chatterings in the background.  I would also assume that I am not the only 
birder who did this, and it would be really interesting to compare recordings.

What I can say is that White-throated Honeyeaters sang during totality and 
lorikeets shut up! And amazingly, some humans totally ignored the event as a 
couple of cars drove past during totality without stopping!!!

For those who have only seen eclipses on TV, the actual experience is very 
different.  I was expecting it to go as dark at night but it was much more like 
what the Scots would describe as a 'gloaming'.

Kind regards

Judith

PS. Thanks to all who provided info on the White-browed Crakes.  We had 
terrific views!
