Parental Feeding Techniques of the Great Blue Heron

Great Blue Herons are colonial nesters – a rookery can have hundreds (up to 500) of nests, usually in dead snags, with one, two or three nests in a single snag.  Because the chicks are in the nest for roughly two months before fledging, their interactions with both parents, especially when food is delivered to the nest, has been observed and well documented.

Newly hatched chicks peck at the adult’s bill, the nest and each other. Initially the adult returns to the nest  where it stands on the rim and regurgitates food into the open bills of the chicks.  The chicks get quite proficient at grabbing the adult’s bill and pulling it into the nest as soon as the parent returns.  As the chicks age, the adult often regurgitates onto the floor of the nest and the chicks eat it.  When the nestlings are about a month old, they take food directly from their parents.

        I can’t seem to get to it. I’m a bit of a dinosaur with today’s tech.
