Firstly, fantastic videos Steve!
Secondly, I attach a photo from the Botanic Gardens last week. Yes the dragon was gobbled whole, tail still swishing desperately.
There is a story about a Kookaburra and a Lewin's Honeyeater, but you will need to ask Peter Marsack about that one...
Lastly, one of the funniest things I have witnessed while bird watching was a Superb Fairywren eating a decent sized caterpillar whole. It "swallowed" it, but it did not completely fit, and the Fairywren was walking around in circles,
head up, mouth open and the tail of the caterpillar visible in it's beak....
