Both yesterday and today (Wed. and Thu., Nov 18, 19) an immature
Cooper's Hawk was soaring over the Mall, near the Smithsonian
Castle. In both instances, it was the behavior of starlings
and crows that alerted me to its presence - the crows chased
it, and the starlings formed up into flocks and the flock
chased the hawk.
