Pied-billed Grebe - Juvenile

Last Friday along the auto tour at RNWR, as I passed marker 12 at the beginning of the last canal, I was hopeful that I would find something interesting. It's not uncommon to see American Bitterns along this stretch, though the occurrences have tapered off with the coming of summer. No luck with Bitterns, but I did get some good looks at my first juvenile Pied-billed Grebe.
This Grebe was dining on minnows. It didn't completely dive under the water like an adult. Instead, it would point its head straight down as if looking deep into the water and then plunge its head in, many times successfully retrieving one of the small fish. I have never seen an adult stare down into the water like this juvenile did.
