Here's a very small bird with a very large eye ring.
Native to Australia and New Zealand, he's a migratory bird called a silvereye. He's only the size of a kinglet.
Right now the silvereyes are gathering in flocks because winter is coming to the southern hemisphere. They'll fly north to warmer climates eating fruit along the way.
Here's a video of them eating kiwi at a backyard feeder. (I'll bet the bird that's flapping its wings and cheeping is a fledgling. What do you think?)
The eye ring is amazing...
Look me in the eye, he seems to say.
