Raven's Call
By Ron Mastrogiuseppe
Leftovers from last evening's picnic just became a meal for ravens.
They busily share with each other and fly to nearby trees to cache
portions of food. Why would the first raven on the scene call others to
share the find? They even allow a curious doe to approach and inspect
the table, perhaps knowing that she will not be interested in chicken
parts! The raven hops sedately but gives cautious, sideways jumps
approaching the food. Their wings are half spread, poised for immediate
takeoff. Only now do I remember that during the cold days of winter, a
few opportunistic ravens are among the few commonly seen wildlife
species in Rim Village, where they observe human visitors at lunch and
play.
Ravens (Corvus corax) are the largest members of the crow
family. This family also includes the smaller crows, as well as the more
brightly colored nutcrackers, jays, and magpies. All are known for their
learning abilities, especially in retrieving food caches. More than a
hundred species are grouped into the family, one whose scientific name
is Corvidae. Ravens are recognized by their large
sizenearly twice that of the American crow. Whereas crows have
square-shaped tails as well as blunt and splayed wings, ravens possess
long and wedge-shaped tails, along with pointed wings which span up to
four feet. There are no color differences with respect to gender among
ravens, though males are slightly larger than females.
These birds historically followed the migrations of large game
animals and tended to associate with predators such as bears, wolves,
coyotes, and humans. Large predators not only killed game such as deer,
elk, and caribou, but also were necessary to open or tear apart
carcasses. Where humans subsisted as hunters, ravens frequented villages
and played the role of scavengers. Ravens have disappeared from large
areas of western and central Europe due to persistent persecution by
farmers and gamekeepers. In contrast to crows, the raven has not adapted
to urban areas and tends to be seen in the wilder portions of its former
range. It still enjoys a wide geographical and ecological distribution
(something that extends from the Arctic Circle to mountainous regions of
Central America), however, and associates with humans in places where
ravens have not been mistreated or continually harassed.
The raven occupies a prominent place in the lore of many cultures. To
some Indian tribes of the Pacific Northwest, the raven is responsible
for the creation of the earth, its moon, along with the sun and stars,
Other groups have believed that ravens controlled or affected the
weather. Associating ravens with death on the battlefield probably led
to the assumption that these birds were somehow harbingers of doom. This
comes through in western literature, where the hoarse croaking of ravens
is often symbolic of evil and impending destruction. In William
Shakespeare's Macbeth, for example, the raven is the one who
"croaks the evil entrance." Edgar Allen Poe's description of the raven
is also ominous:
"Ghastly grim and ancient Raven wandering from the Nightly
shore Tell me what thy lordly name is on the Night's Plutonian
shore!" Quoth the Raven, "Nevermore."

Next time you are on the rim and have the feeling you are being
watched, you probably are. Ravens have prospered because they are
exceptional observers with remarkable memories. They can successfully
collate and retrieve information, while recognizing cause and effect
sequences. Such ability assists the ravens in acquiring sustenance and
allows them to feast on an amazing array of foods. It may be well to
remember as we bear witness to ravens observing human activities in
picnic areas, this is opportunistic behavior predating (by millennia)
the sign reading, "Do not feed the wildlife." This National Park Service
policy nevertheless makes sense in light of human visitation to parks
being comparatively heavy, and wildlife numbers relatively few, such
that the potential exists for creating dependence on humans for
food.
It is nearly 6 a.m. and from my viewpoint at Crater Lake Lodge, I see
the sun rising above the northern edge of Cloud Cap. During the past
hour prior to sunrise, the high ceiling of clouds remaining from
yesterday's lightning storm has been aglow with orange hues reflecting
the lake's quiet waters. Mirrored images of the inner caldera walls and
Wizard Island appear as perfect, while the shoreline seemingly
dissolves. Volcanic rocks below the west rimthe Watchman, Hillman
Peak, Llao Rockare awash with early sunlight that constantly
changes the display. The few human visitors, so ephemeral amid this
scene, try to record through cameras yet another sunrise on the edge of
what was once called the Sea of Silence. It is now one month since
summer solstice, when the sun shone at its northernmost point just to
the east of Wineglass slide.
Just as I began to think about shorter days, my attention suddenly
turned to the Rim Picnic Area where three ravens were loudly squawking.
Their bold black forms dove and swirled amid the dark green foliage of
the old mountain hemlocks. This time they seemed to be at play,
indulging in aerial acrobatics. Their antics include nose-diving with
wings closed, turning, tumbling, and even somersaulting, then gliding
upside down. With voices deep and penetrating, the ravens command
immediate notice and respect. A guttural croaking echoes through the
light breeze this peaceful morning. What are they saying to one another?
I believe these birds have the answers, but they are not talking to
us!
Ron Mastrogiuseppe has listened to the birds at Crater Lake
National Park since his first visit almost three decades ago.
