On the wing, and under it

One of fluctuating hundreds of Wandering Whistling-Ducks (Dendrocygna arcuata) on the main lagoon these days takes a turn near the Tyto lookout. Plenty of Plumed Whistlers too, but usually clustered on grassy banks of new lagoons near the info centre.

Young White-bellied Sea-Eagle (Haliaeetus leucogaster) about to make brief touchdown near the lookout. Interesting that one- to two-year? bird caused no alarm among the many birds on the water, very different from reaction mature eagles usually provoke. But perhaps there’s something about eagles’ in-flight behaviour that signals either malign or benign intent.     

Nothing much malign about Spotted (Turtle-) Dove (Streptopelia chinensis), showing delicate colouring on rail in the morning sun. Not universally loved because regarded as pushy import (1860-1920), at least the mostly suburban species no longer is tagged an STD.

The sea-eagles at Hastie's Swamp don't always cause a panic response among the ducks, so maybe there's a hunting and non-hunting style? (Or --- more likely --- I haven't been paying attention.)

Whatever our states of attention, it's life or death for ducks, so probably eagles' intent is readable: if only we read Eaglish!

Adding something extra to Spotted Whistling Duck

So, too many Spotted Whistling Ducks lately? No, wait, this isn't yet another one on the new borrow pits in the Townsville Town Common...
