On Wednesday 15 December just after 15h08, there was action at the Bat Hawk nest. The female Bat Hawk came to the nest and appeared to snuggle up to the cup in the nest. She spread her wings over the nest, presumably when she laid an egg, then proceeded to lie deep in the nest.

The male joined her at 16h26 for a short while, and again at 19h34. There appeared to be a change over at 19h49 when the male stayed on the nest, presumably incubating an egg. The female came to relieve him at 21h16. The male again came back to the nest to incubate at 21h48. The female relieved him at 23h06.
