Loons are fun birds to watch. I took 3 kayak trips on a lake over three days. Each time I watch these loons for an hour or so. I have a zoom lens ,an extender and these are cropped.
The lighting changed even within the hour or so I watched them this day. It depended on which way they were facing, cloud cover, and what objects they were near. In this case I believe the green colour was a reflection in the water from a boat cover. The mom kept the little one near the shore of the lake.
The parents kept parading around with small fish that seemed much too big for the baby. I think the baby finally ate them when they cut them in pieces. It is fun to watch nature. Loons are becoming my favourite birds. They have such personality.
