Black Vulture

Fascinating facts about the Black Vulture

• A black vulture can span up to 1.67 m (66 in) from wingtip to wingtip, making it an imposing sight in the sky despite being smaller than many raptors. Its weight varies by region: North-American birds average 2.15 kg, while Venezuelan individuals average 1.64 kg, and tropical lowland birds can be as light as 1.18 kg. This size flexibility lets the species thrive from the temperate Midwest to the humid Amazon, exploiting both open fields and forest edges for carrion hunting.
• Black vultures locate food mainly by sight, often trailing turkey vultures that use a keen sense of smell. When a carcass is spotted, the black vulture's aggressive foraging style can drive the more solitary turkey vulture away, securing the meal for its flock. This visual hunting strategy, combined with group pressure, gives the species a competitive edge at carcasses and helps recycle dead animal matter before disease can spread.
• A single breeding pair typically raises two chicks, each hatching after 28 to 41 days of incubation. The young stay in the nest for about two months, then spend 75 to 80 days mastering flight before leaving the roost. This relatively rapid development, paired with the parents' habit of regurgitating crop milk.
• Black vultures can safely consume decaying flesh laden with pathogens. Their stomach lining and liver may secrete antimicrobial agents, and their gut microbiota likely contributes to this resistance. They scavenge at garbage dumps and road-kill sites.
• The black vulture enjoys legal protection under the Migratory Bird Treaty Act of 1918, making it illegal in the United States to take, kill, or possess the bird without a permit, offenders face fines up to US$15,000 and up to six months in jail. This status, combined with an estimated 50-100 million mature individuals, keeps the species at Least Concern on the IUCN Red List.
