The black throated finch is a pretty enough bird, but of course cuteness should not matter when it comes to extinction of a species.
Of course the kookaburra was in the top ten in the bird poll. My maternal grandparents used to refer to kookaburras as laughing jackasses. What is a jackass? Back in minute while I check. I is returned. Well, it means a male donkey, but the Cambridge Dictionary also adds, Australian old fashioned; kookaburra.
You probably don't recall or did not read my blog back in 2013 when R's sister and her then husband visited Australia and stayed with us. Take a look at the whole post (lots of pretty birds) if you want or this hot link to a picture of kookaburras lined up ready for a breakfast treat of minced beef while we were drinking champagne and orange juice before we had breakfast on a verandah in Walhalla.
Wikipedia says they are terrestrial tree kingfishers. I came across this great video of them on someone's balcony somewhere on the Gold Coast where he clearly feeds them. It is illegal to feed native birds and wildlife but no one takes much notice and I've never heard of anyone being fined. The important thing is that they don't become dependant on humans feeding them and don't lose their ability to hunt or find their own food. Laugh along with the kookaburra.
