~~Black vultures prove you don’t have to be beautiful to enjoy a committed, long-term relationship.~~ Um, rude.
Looking dressed more for a funeral than a wedding, these scavenger birds feature all-black plumage with bumpy, featherless grayish-black heads, and short, hooked beaks.
Found in open habitats and along roads from the southeastern United States to South America, black vultures are all about family life. They form bonds that last their whole lives (about 10 years).
