This is the story of the shrike that did not attack. I like to
read or write in our sunroom overlooking the back yard, glancing up
occasionally to see what the thrashers, hummingibrds or chachalacas are
doing and also hoping to see new species of birds and butterflies for
our property list. Recently I noticed a robin-sized bird perched
alertly on the top wire above our fifteen-foot privet hedge. It was a
Loggerhead Shrike, intently focussed on a smaller bird a yard away on a
lower wire.

The latter was a Yellow-throated Warbler, a mostly southern
bird impressively colored with a gold gorget finely lined in black,
white underparts and gray plumage. This little jewel was nervously
twitching back and forth on its perch, and I don't blame it because the
shrike is an efficient predator, and it seemed to lean forward and down
in attack mode. About nine or ten inches long, its whitish breast and
gray back are combined with a rather piratic black mask, black wings
with whiite trimming --- and a wickedly hooked beak.

I have seen shrikes cause our feeder birds up north to become
fear-stricken statues or vanish instantly not to return for hours. Once
a shrike swept in and lifted a goldfinch off the feeder deck, carried it
away and, I assume, killed it in its usual way of hacking the skull with
that beak. They do not have the killing power with their talons that a
hawk or owl possesses; their feet are rather small.
There are two species, the Northern, called the Migrant Shrike,
which we see in Michigan in the winter, and the Loggerhead, which is the
one you will see in the Valley. The name comes from its cabeza grande;
a loggerhead is a long handled tool with a large ball at the end which
was heated to be dropped into liquid for warming or for melting
substances such as tar. The word "shrike" is derived from the Middle
English word for shriek,"shriken." They do make some weird sounds,
although they seem more raspy than piercing.
"The Butcher Bird" Loggerhead Shrike

An interesting apellation for this creature is the Butcher Bird
because it has a custom of hanging its food supply, insects, birds,
snakes or rodents, on a thorn or a barbed wire fence. Nothing like aged
meat, you know. The shrike can take larger prey like a Mourning Dove,
and it has been seen catching snakes as large as 16 inches. The main
diet in the summer months, however, is insects. Even wasps are readily
handled, usually held by the abdomen while the stinger is rubbed off on
a branch.
I wish I could tell you the outcome, but they both flew away without
hint of pursuit. All I can suggest is that watching the creatures
of the wild is as strange and absorbing as watching human behavior: that
which is bizarre may be the norm.
