Doug,

This is interesting behavior!

I have visited the park several times and seen a lot of ducks and swans but never this bird.

I am impressed that it would venture to eat such a complex geometrical shape, especially as it is covered with an exoskeleton armor plate articulated shell! I have seen sea birds drop these from a height on rocks and so smash them to get access to the meat. Is this bird going to do the same or do the odd pieces get somehow twisted off and swallowed without loosing the rest of the crab to another scavenger?

Classy stuff Doug.
Interesting portraits. They seem slightly distant or other-worldly.
Trying to humanise animals' personalities is always difficult but extremely captivating.

The bird ate the crawdad out of my sight so I don't know for certain but I believe it's eaten whole. The American Bittern eats them whole.

I guess they crush them and then everything becomes flexible and then they just swallow, LOL! I saw videos of herons eating birds or a pelican eating a rabbit. These are really dinosaurs with normally good manners.
