What's black and brown and blue and sad?

What's black and brown at the same time? Immature rufous morph Black Butcherbird (Cracticus quoyi race rufescens), as seen from distance in Tyto today, with black splotch on breast showing the all-over colour to come as bird begins second moult on way to turning black.

What's black and brown at the same time? Pair of Eastern Koel (Eudynamys scolopaceus). But the streaky brown female wouldn't sit still in fig tree with male above at Mungalla stockyards.

What's black and blue without being bruised? Male Shining Flycatcher (Myiagra alecto) foraging on ground near Mungalla stockyards.

What's black about nesting Mangrove Robin (Peneonanthe pulverulenta)? Finding her gone yesterday and no sign of the two hatchlings from two days ago. Snake? Frog?  Raptor? Third tale of sorrow for the pair: nest abandoned; eggs snatched; hatchlings taken. Bugger. Bugger. Bugger. Better luck next time?
