"Watch out"

When walking back from the beach I saw two Australian Magpies on neighbours TV aerial. After the first shot where they are seen "singing" (see Extra 1) they were buzzed by this Asian Myrna bird? (Main photo). The third shot shows the larger (male) bird taking flight. Still experimenting with the new camera and lens so I had trouble getting better shots in the low light from so far away. Lots to learn.
