Greater Roadrunner (Geococcyx californianus)

Posted on by

A member of the cuckoo family, the long legged Greater Roadrunner (Geococcyx californianus) is an icon of the desert southwest in part to the artistic efforts of Warner Brothers and their animated series featuring “Wile E Coyote”. Road runners are aptly named and may reach a top speed of 26 mph on the ground. Anyone who attempts to stalk them will note their speed and agility as they effortlessly out distance the stalker.

The road runner is a larger bird than one might realize and typically is between 20 and 24 inches in length. The bird is typically between 10 and 12 inches in height and boasts a wing span on 17 to 24 inches. The upper body is a shade of brown with black streaks and may feature pink spots. This pattern helps break up the outline of the bird and helps provide camouflage. The lower body is commonly white or ran in appearance. The head features a prominent crest of brown features.

Despite the branding and name, the greater roadrunner is capable of flight, although it spends most of its time on the ground. This animal can be found at most elevations between -200 and 7500 feet and favors semi arid scrubland with scattered low lying vegetation. The bird spends its time hunting and stalking its prey. Once sighted prey is quickly run down by the fast legs of this peditor. Common prey items include spiders, insects, scorpions, mice, small birds and lizards and even rattlesnakes.

The greater roadrunner typically forms long pair bonds with its mate. Typically, clutches of 3 – 6 eggs are laid in the spring months. The nests of this bird are commonly found in low brush and cactus and are built by the male. Common with other cuckoos, the roadrunner are known to lay eggs in the nests of other birds, such as the raven.

Commonly known as an antelope, the Pronghorn ( Antilocapra americana ) is an even toed or hoofed mammal found in the plains of the western United States of America. The Pronghorn in america is mislabeled as an antelope, which is an old world or African species of Antelope. The Latin name, Antilocapra americana means “American goat-antelope”

The Pronghorn lives in brush and grass lands and deserts and survive by grazing on the vegetation. They typically live in herds which may number in the hundreds depending on time of year and food sources.

They have excellent eye sight use this valuable resource to keep a distance from predators in the wide open habitats they are found. They are also the fastest animal in the western hemisphere and can run at speeds up to 60 miles per hour. The result is a reclusive animals that tends to run when it sees any threat, which means these animals can be difficult to get near. Typically, when I see them in the field, it is their white hind quarters travelling at a high rate of speed away from me.

Males typically stand between 51 and 59 inches in height and weigh between 88 and 143 pounds. The female are about the same height, however, more slight at 75 to 106 pounds. Their coloring is quite distinctive and features large white patches on the rumps, belly and heads with black bands on the face and necks. They boast large eyes located towards the tops of their skulls which have a field of view of 320 degrees. This feature allows the animals to maintain distance and allows them to spot predators while resting in the tall grass.

Cougers, Coyotes, Wolfs and Bob Cats are known to prey on the pronghorn. Additionally, they were a valuable food source for many Native American tribes including the Assiniboine, Rapid and Blackfoot Tribes.

A symbol of the American Southwest, the howl of the humble Coyote (Canis latrans) is synonymous with wild places. A member of the canine family and cousin to your pet, the coyote is a carnivore, predator, scavenger and survivor and even have a gord named for them, the coyote melon. The mammal is also known as the “little wolf”, “brush wolf”, “prairie wolf” and “American jackal”.

Although not necessarily nocturnal, they may hunt at night in the presence of humans. Regardless, they are more active in the evenings. They prowl and hunt in small groups. Their cries and howls at night are the reason they are known as the most vocal wild animal North American Animals. Personally, I welcome their vocalizations echoing access the desert night.

Coyote hunt reptiles, birds, small mammals, fish and even the larger bison, deer, elk and sheep. They roam up to ten miles per day on a constant hunt for food. In urban areas, this opportunist animal will eat dog and cat food, and known to attack domestic dogs and cats. In Death Valley National Park this resourceful jackal will eat large quantities of beetles and hawkmoth caterpillars for food. They are extremely resourceful and opportunistic survivors.

The coyote is classified in 19 different subspecies throughout the North America. A typical male will weigh between 18 and 44 pounds, while the female tips the scale a at a more modest 15 to 40 pounds. The fair color ranges from a light grey, tan to dark browns or even black depending upon habitat.
