One of the Great Blue Herons with a dead snake it just lifted from the nest.
As I watched, this bird took six dead snakes from the nest with the chicks and proceeded to swallow them.
At this stage, the chicks can not eat solid food so the parents put dead fish, snakes, etc. in the nest to orient the chicks and to let the chicks peck on the kill.
Then the parents eat the kill and regurgitate feed it to the chicks.
