Greater Roadrunner
Copyright Barbara Samuelson 1998
Greater Roadrunner (Geococcyx californianus), Death Valley,
California
The roadrunner can fly, but prefers to use the highways that man has
so kindly provided to sprint after its prey. Not only can it reach speeds
of up to 42 kph (25 mph), but it takes corners without slowing down. Its
uses its long tail as both a rudder and a brake. It simply flips its tail
up when it needs to slow down. The roadrunner is powered by solar energy.
At sunrise it stores the sun's heat by raising its feathers and exposing
a dark patch of skin on its lower back. The roadrunner is a kind of ground
cuckoo that lives in the desert scrub of the south western United States.
It eats insects, scorpions, lizards, snakes, rodents and other birds,
although it may switch to a vegetarian diet during the winter when its
usual prey is scarce. It is so quick it is able to catch and eat rattlesnakes.
It grasps the snake by the tail and bashes its head against the ground
until it is dead. Their song is a dovelike cooing, descending in pitch.
