Pink Robin (Petroica rodinogaster) by Tim Collins Tasmania IT'S A REAL THING! The Pink Robin is a small passerine bird native to southeastern Australia. Its natural habitats are temperate forests and subtropical or tropical moist lowland forests.
The Japanese White-eye (Zosterops japonicus) is a small passerine bird in the white-eye family. Its native range includes much of east Asia, including Japan, China, Vietnam, Taiwan and the Philippines.
I've seen small birds drive away an owl before, and I think that's what is happening here between a songbird & a Barn Owl. It's astonishing to witness the bravery of small creatures protecting their young and/or their territory.
