Tyrannus tyrannus.
Lake Umbagog.
1907,
August 10.
  Despite his fearlessness in attacking Hawks and Owls the
Kingbird - like many another bully under similar circumstances -
sometimes gives way and seeks safety in ignominious flight when
assailed by a bird not larger and apparently no more powerful than
himself. I saw this happen to-day when a Yellow-bellied Woodpecker
pursued and overtook a Kingbird in a cove behind B Point. The two
birds passed me within ten yards when I saw the Woodpecker deal
repeated blows at the back of the Kingbird who was doubling and
twisting all the while and giving his shrill alarm notes inces-
santly. After they had separated the Woodpecker alighted very
near me on a stub when I was surprised to find that it was a young
bird, apparently a female.

  The Kingbird has not learned, apparently, to discriminate
between Hawks of dangerous and harmless kinds. I saw one pursue a
Fish Hawk for some distance this afternoon rising above it and
darting down to peck at its head and back. Half an hour afterwards
I was sitting in my sailing canoe when this same Kingbird alighted
on the mast which is only about 6 feet in height. It remained
there only an instant, however. The sail was not hoisted at the
time.
