The Turkey Vulture

One of the most common large birds in many parts of North America, the majestically-soaring turkey vulture is rarely as appreciated as eagles, hawks, or even the closely-related California condor.
Part of the reason the turkey vulture never gets its due may have to do with its looks. The bird gets its name from its bald head and dark plumage resembling that of a wild turkey. However, once this vulture spreads its six foot wings and begins soaring, it’s obvious this is no turkey.
Often incorrectly referred to as buzzards, which is actually a European term for many buteo species of hawks, turkey vultures can be found throughout South America, Central America, and southern parts of the United States year-round; in warmer months they may live as far north as Canada. They primarily live in large roosts of up to several hundred birds and prefer open country over heavily forested areas.

Turkey vultures are scavengers that feed almost exclusively on carrion. By removing and consuming animal carcasses, they perform an important role in local ecosystems by reducing the spread of disease.

Turkey vultures are sometimes unjustly blamed for killing newborn cattle. In reality, this is usually the work of the black vulture, a similarly-sized bird that sometimes does roost with turkey vultures.

Though not currently endangered or threatened, the turkey vulture is protected under Migratory Bird Treaty Act of 1918. Killing or possessing a turkey vulture can result in a $15,000 fine and six months in prison.

Saving the California Condor

The California condor is the largest bird in North America. With their nearly 10 foot wingspans, these majestic scavengers have never had any real natural predators, yet they became nearly extinct just a few decades ago.
California condors were plentiful throughout the southwest United States and northern Mexico until relatively recently. However, loss of habitat, egg poaching, and incorrect assumptions by ranchers who thought the massive birds had actually killed the livestock carcasses they were feeding on led to the California condor’s decline. This combined with the fact that the birds mature and reproduce very slowly meant that even after the species received protection, populations did not recover.

In 1987, conservationists made the unprecedented move of capturing all 22 California condors remaining in the wild for a captive breeding program at California Zoos at a cost of 35 million dollars. By 1991, the birds began being reintroduced in the wild at national parks and wildlife sanctuaries in California and Arizona. California condors can live up to 60 years, and as of April, 2011, there are 181 of them living in the wild, with an additional 200 in captivity. Hopefully this majestic animal, a symbol for the southwest its native tribes, will flourish again in years to come.
