|European Magpie, Madrid. A crow.|
It was the colour combination they seized on.
|Common Fiscal Shrike, Cameroon.|
There are no true shrikes in Australia, but several 'shrikes'; the relevant aspect here is the predatory hooked bill.
|Austral Thrush, Chile.|
There are a couple of true thrushes here, but the name has been applied to some non-thrushes,
in reference to the song.
|Horsfield's, or Singing, Bushlark (juvenile), Canberra.|
This is Australia's only native lark, but the family is abundant elsewhere; again the song is probably the relevant feature.
|Great Tit (from the web)|
Here the colour combination was the basis of the choice.
(The group is known as chickadees in North America.)
|King Quail, captive birds.|
Apparently the only relevant aspect of them is that they live on the ground...
Perhaps the most convincing of them, with the tit's colours and the shrike's bill.
|Grey Shrike-thrush, Fraser Island.|
Again the shrike bill, with a glorious song (if I'm being parochial I reckon it's better than any thrush!).
|Black-faced Cuckoo-shrike, Canberra.|
The shrike bill again, with a sort-of cuckoo-like dipping flight... Mmm.
|Magpie-lark male, Canberra.|
The black-and-white (ie magpie) bit's OK, but lark? Great bird, but not melodious!
|Spotted Quail-thrush female, Namadgi National Park, near Canberra.|
This is a total mystery to me. Quail presumably for living mostly on the ground; and it sings a bit (like a thrush?),
but really! This one is impressive too for joining not only two different families, but two separate orders!
