Greater Roadrunner
The
greater roadrunner (Geococcyx californianus) is certainly one of
Oklahoma’s most fascinating birds to watch. Powerful legs, a
long tail, oversized bill and shaggy crest give the birds a
prehistoric flair that makes them unmistakable among the state’s
avian residents.
Roadrunners came by their name naturally. They can sprint up to
20 miles an hour, and will only fly as a last resort. They are
actually members of the Cuckoo family, which may explain the
comical antics they often perform. They are, however,
intelligent creatures and are quite curious about human
activity, often shaking their tail from side to side as they try
to figure out what we humans are doing.
These crow-sized predators are skillful hunters and are not
picky about what they eat. A roadrunner’s diet consists of about
90 percent animal matter; the remainder is fruit and seeds.
Roadrunners are perhaps best known for their appetite for
snakes, but they will eat anything they can kill with their
sharp beak including lizards, rodents, insects and even other
birds. They often control animals that are considered pests.
Roadrunners may look tough, but they are attentive and
meticulous parents. During the spring, a male roadrunner can
often be seen carrying a lizard or small snake as an offering to
attract a mate. Although they spend most of their lives on the
ground, the parents will build a nest up in a tree where the
female lays four to five nearly spherical white eggs. The
parents share the incubating duties and once the eggs hatch,
they are both busy feeding their voracious youngsters. The
chicks are ready to leave the nest when they are around three
weeks old, but their parents will continue to teach them how to
hunt for several more weeks.
Roadrunners often live in extreme climates and are uniquely
adapted to conserve energy. On cool nights, they lower their
body temperature and become lethargic. In the morning, they use
a built-in heat exchanger, a patch of dark skin on the back
between the wings, to help absorb the warmth of the rising sun.
They manipulate their feathers to expose the patch, then find a
suitable sunning place and wait for their body to reach normal
temperature.
These entertaining birds are not particularly vocal, but they
have a wide repertoire, from soft dove-like coos to low,
guttural notes to sharp, high-pitched barks.
Greater roadrunners prefer open country with little brush to
slow them down. That is why they can often be seen along
roadsides. At one time, roadrunners were considered birds of the
desert southwest, but their range has expanded east through
Oklahoma into Louisiana and Arkansas.
The next time you are in Oklahoma’s outdoors and you see the
bright yellow eyes of the roadrunner checking you out, take a
minute to look back. You might be pleasantly surprised at what
you see.
