They're back and they've been busy!
Nest re-occupied: Kath first noticed the adults around the nest site in mid-January, though they may have been around a bit earlier. From the 21st January we noticed them on the nest continually, so were sure that they had returned and were propagating an egg (or eggs). We have enjoyed some great views of the adults on the nest and soaring locally. They are easier to view this year, it seems they are sitting higher on the nest somehow (or have slightly shifted its position) as we are consistently getting full views of their neck and head.
Hatching: Kath noticed a lot of commotion on the nest on sunday 28th March so she believes the youngster has hatched. If 2 eggs are laid, they are normally a few days apart; this is an 'insurance policy' and assuming both hatch the stronger predates the weaker (or the parents simply ignore the weak one and it dies).
ETD! Assuming all goes well with the rearing, the young takes several months to grow and its first flight should be scheduled for sometime in end July / beginning August!
