Sept. 4. ½ day, at 10 a.m., I saw for the first time, I think,
in my whole experience, a Great Blue Heron actively engaged
in fishing. He alighted on a point in Leonard's Pond and after
looking keenly about for a moment waded out into the
water up to his belly and began marching back & forth
striking several times each minute. He carried his neck
stretched out to nearly its full length and invariably
held to one side (low to one side) of the central axis of
the body with his head & bill turned up backwards as
if he were blinded in one eye. This posture was assumed
of course. They are rather rapid but made with as
much deliberation as those of a hen picking up corn.
The whole performance was as different as possible from
what I had imagined it. The bird often stood motionless,
walking or rarely paused for more than a moment at a time.
Once I saw him pull up a trout fish which
he shook violently & then swallowed. All his other attempts
were either fruitless or he caught fishes so small that I
could not see them (he was 100 yds. away & I had a good
glass). This was something like his fishing attitude:
