A couple of months ago we saw a Whistling Kite carrying sticks into a copse of Angophoras next to our house, Eventually we saw the nest, clearly visible from our deck. The birds started sitting in it and (after a pause of about 3 days during a very gusty period) a bird occupied the nest for most of September. Then they left the nest and after a couple of days were seen carrying sticks to a different part of the copse. I have yet to spot the (presumed) new nest. Yesterday a bird spent most of the day sitting in the old nest.
Are they in fact laying eggs in this process or just practicing building a nest?
