I thought they sat in gum trees. Good captures, and the images take me back to about 1969-70. Hard to get within photo range of our king fishers. I think they're psychic and know precisely when one's index finger is approaching the shutter.
Kookaburras can become very tame, especially if you feed them. It's quite normal to have them eating out of your hand. My neighbors feed them so they're not afraid when i get close to take a few pics.
