Back to our local duck pond, this time to observe a ring-necked duck. I always chuckle at their name. Why not 'ring-billed'? Only in the very best light and very close can I see a dark brown ring around the neck of the drake.
In the middle part of the page I was watching how he slicks down the feathers on his head just before he dives. Normally he has a little lump back there, but it virtually disappears.
