Magpie-lark sees off screaming Koel

Male Eastern Koel (Eudynamys scolopaceus) screams  after being seen off by Magpie-lark (Grallina cyanoleuca) anxious to avoid being parasitised, though few female Koels seen yet. 

Masked Lapwing (Vanellus miles) screams toward the camera as a pair of the aggressive breeders defend a patch of footy field near Tyto Wetlands.

Brahminy Kites (Haliastur indus) too pretty to scream.

Even when one approaches their nest near Dungeness the response is merely a mew.
