before gliding off, ghost like, through the densely
falling snow flakes out over the river. Although
most of the Sparrows & Juncos had taken flight
with loud cries and sought refuge in the trees,
a moment after the Hawk struck at their

only a short distance off evidently having
failed to take the alarm. Thus had I not
come on the scene in the nick of time the
Hawk would probably have had a chance
for another stoop with good hope of success.
Even the birds which had flown up into the
trees did not seem greatly frightened although
they did not venture to return to the ground
for several minutes after the Hawk had gone.
