We have Kookaburras with a nest hole in a termite nest, high in an ironbark eucalyptus and their young are busy calling for food deliveries.
I have been trying to get a photo of a delivery but the adult kookas will not go to the nest if they spot any potential threat. Without a hide I am obvious and that says maybe I am a threat so the adults will wait nearby until I depart before making a delivery.
I did manage to get a photo today with an adult about to deliver a large stick insect as the meal for the young.
Not wanting to delay deliveries, I don't visit the site often but keep a distant watch on the nest, listening to the young calling. The biggest threat is from the lace monitors, if they can get to the nest without being detected by the adults. If seen the adults will attack and generally drive the lizard off.
