This post is with a little intruige, and even though the images are distant and somewhat fuzzy, I think you'll be intruiged along with me.
Don't we get caught out sometimes? Was indoors and stopped to think about a noise I'd heard in the distance out there somewhere, several times over. Went out; was it a duck or ....?? Looked to the trees out the back, nothing. Walked around the house, then saw, up in the sky long ways away, two big birds gliding around on the thermals.
Goodness!! Go get the camera!
I'm thinking a pair of White-bellied Sea Eagles. Cropped images; see what you think .......
the one on the right, it has differing markings around the top of chest, white marks on the wing extensions... so maybe it's still a juvenile?
it takes two to tango?
Someone's house roof is showing at the bottom left of this photo unfortunately and I guess the focus went to it, instead of the birds for this one
Shame they were so far away, better luck another day!
As for the voice, my Readers Digest Birding reference describes it as 'harsh, metallic, goose-like'
