Have you ever seen a Yellow Crowned use bait? They will find a scrap or a leaf, anything that might attract fish, drop it on the water and then just wait.
They are around here but stay way out in the marsh most of the time.
I've never seen a Yellow Crowned use bait. They are the premier crawdad catchers around here though, although I've seen Grebes, Ibis, and even American Kestrels catch crawdads. I usually try to go on a picture taking expedition in late May or early June when the crawdads are in shallow water and apparently easy for the birds to catch.
Snowy Egrets vibrate their feet in shallow water to scare prey (crawdads, minnows, tadpoles, small fish) and make them move. That's a wicked looking beak on the Snowy below.
