to create shade to attract prey.
The latter technique is taken to
extremes by the black heron,
which stretches its wings forward until they touch to form a
tight canopy over its head.
Egrets, especially those with
bright contrasting feet, like
snowy and little egrets, are
quite fond of using their legs.
While walking slowly through
the water, they sometimes
sink their feet slowly into the
substrate, and on occasion,
actually vibrate one leg, with
the purpose of stirring up prey
items from the bottom.
Probably the most interesting foraging strategy used by
green herons is baiting. This
innovative technique, which
has elevated the herons high
up the list of the smartest birds
on the planet, involves the bird
laying down pieces of vegetation, bread, or even insects as
bait for fish.
Well, there you have it.
The truth has been told. I am
grateful to Ron Klowden for
helping me to not only set the
record straight, but also for the
chance to delve into and pass
on some intriguing prey-cap-ture behavior by these highly
evolved birds. a
