. . . an occasional large and dramatic avian visitor to our garden — about 30′ up, climbing around in one of our several Grevillea robusta trees.
Also known as Lady Ross Turacos, the birds are about 18″ long with mostly dark blue feathers. I got a very quick look at the ends of this one’s wings — bright red and only visible in flight.
I have seen them in different tall trees around the garden before — the last time in a pair. The males and females look exactly alike.
Today, this one was making only a noisy, repetitive croak, which drew me to look for it. But, previously, I have also heard them make a more melodious call, which I remember as sort of a loud cooing sound (a contradictory description, I know).
My soul into the boughs does glide;
There like a bird it sits and sings,
Then whets, and combs its silver wings;
And, till prepar’d for longer flight,
Waves in its plumes the various light.— Andrew Marvell, from “The Garden“

What an amazing bird! I checked out the red wings when in flight–pretty dramatic.
I had seen Ruwenzori Turacos down in Nyungwe Forest, so it’s been a thrill to find the Ross’s here. And I wish I could capture all the colorful little sunbirds that we have, but my camera is too slow.
