Black crowned night heron-pellets?

[Anonymous]

I know that some birds produce pellets of material that cannot be digested. Is this true of most birds or just a few. I know owls do it but I didnt know herons did it as well. I was watching a bcnh the other day and it produced a pellet. I dont know much on this subject and would like to name this activity properly when naming the shot on my website.
Thanks

Here is the shot I am speaking of.
