What Bird Is This? In NSW?
i live in nsw and trying to identify a bird
its black and has a dark blue stomach that blends in with the black
it flys low and everytime it flaps its wings it pushes itself up a bit
it would be better if you have a photo of it but here you can see all spieces of birds in NSW, which might help you a bit
