Scientists, as a result of poor concepts involved in conducting experiments, concluded that birds could not smell. However, better devised experiments of more recent times have shown that birds can indeed smell. Turkey Vultures, that at one time ignored rotten meat placed under a log, do have a very good sense of smell. It’s no surprise that they react very quickly to a recent kill.
Although they are meat eating birds, they do not kill, but survive on carrion. They soar very high, and with their excellent eye sight, can survey a large area in search of dead animals. While perched, you can see their red head and brownish/black body. But in flight, the silvery/white trailing edges of their wings are now visible.
There are 7 species of New World vultures, including the California and Andean Condors. They are two of the world’s largest flying birds with wingspans of over 9 feet. DNA evidence has shown that Old World vultures are unrelated. Their claws, beaks, and behavior patterns are different. American vultures have weak, chicken-like feet which are suitable for running but not for grasping. They must put a foot on the food source to hold it in place while eating. Their beaks are thinner and not as strong as the Old World birds.
Buzzard is not a very attractive term. It is incorrect to use it on American species. It is a term for several hawk species of the Eastern Hemisphere. It does not apply to vultures.
