juvenile white-naped honeyeater?
A challenging ID- would appreciate any ideas though I know the photo is poor.
This raptor flew across the river into the wetland, harried all the way by several seagulls. It stayed fairly low, treetop height- about 3-4m off the ground (although that could simply be due the seagulls harrying it). It was at least 2-3 times bigger than the gulls.
Underwing/underbelly was distinctly uniform pale whitish/grey with some dark colour only along the margins of the underwing and tail.
Osprey are known in the area, but I thought it looked a bit different as the undercarriage colour was solid rather than mottled. Could be wrong.
After considerable observation, I believe this to be a pellet from a Pied Currawong. We get them visiting regularly to our bird feeder and the bowl of water in the back yard.
