This being a traditional day-in-the-park, & the weather bringing out masses of humans, it was a marvel what a day it was for idly sighting raptors, too.
From our picnic rug on the shore at New Farm Park, we could see two Brahminy Kites in the trees across the river, on the bank below the school there (see map-link). One or two of the masses of crows above our heads occasionally pursued the Brahminies — one of whom was carrying sticks among the treetops. http://www.whereis.com/?id=4E7286563137A0
Then on to Nudgee beachfront park, & the bird-hide & mangrove walk (see sat.pic-link): Variously, White-bellied Sea-Eagle, immature, sailed along the beachfront; an Osprey opposite the bird-hide, on low poles near a Black-winged Stilt sandbank (high tide), flushing them as it flopped into the water; a Brahminy Kite pursued by crows (!) above the mangrove/high-tide line; then a beautiful immature Hobby sitting on a mangrove peak just off the park, unperturbed at being harassed by Currawongs, Magpies, Miners, etc… just waiting into the twilight (HANZAB suggests northerly dispersal in autumn, & soaring at dusk for insects). http://www.whereis.com/?id=4E74244E672020
And… could it be that Spotless Crake might be in the mangroves near the bird-hide?
