Vultures: Nature’s Cleanup Crew

Celebrating International Vulture Awareness Day!

International Vulture Awareness Day (IVAD) is a global conservation event held on the first Saturday of September each year. Its purpose is to raise awareness about vultures, celebrate their ecological importance, and promote efforts to reverse further population decline. There are 23 living species of vulture, yet most are facing a serious risk of extinction due to human-driven threats. We’re participating in International Vulture Awareness Day here at African Lion Safari as a reminder that conservation efforts for vultures benefit wildlife, human health, and the environment as a whole.

Vultures are scavengers and are among the few animals that specialize in feeding on carrion; the remains of animals that have already died. While that may not sound appetizing to you or me, vultures provide an incredibly important public health service. By efficiently consuming carcasses, vultures are likely to help reduce potential disease sources before they accumulate in the environment. Their feeding habits can also play an important role in nutrient cycling, returning nutrients to the soil more quickly and efficiently than would occur through natural decomposition alone.

Scavenging has shaped the vulture into one of the most specialized birds on the planet and it’s worth taking a moment to appreciate just how remarkable this is. The body and behaviours of a vulture are well-adapted for conditions that would challenge most other animals.

One of its most impressive features is an extremely acidic stomach, capable of breaking down carrion that might make other animals seriously ill. This powerful digestive system allows vultures to safely neutralize many harmful bacteria and pathogens.

You may also notice that most species of vulture have bald heads and sparsely feathered legs. These body parts regularly come into contact with decaying meat while feeding, and the lack of feathers helps keep them clean. If humans were handling the same organic waste, we would rely on personal protective equipment and thorough handwashing to avoid contamination.

Vultures, however, have their own sanitation system. They often excrete on their legs and feet, a behavior known as urohydrosis. While it may seem unpleasant, this adaptation helps reduce bacterial growth and may provide additional cooling benefits.

Lastly, vultures are well-adapted for searching vast landscapes for food. Their broad wings allow them to soar effortlessly on rising air currents. Rather than constantly flapping their wings, vultures can spend hours gliding high above the landscape. This efficient style of flight allows them to search enormous areas for food and quickly locate carcasses that might otherwise go unnoticed. In Africa, Europe, and Asia, many Old World vulture species use their exceptional eyesight to spot carcasses on the ground. In the Americas, New World species such as the Turkey Vulture also possess a highly developed sense of smell, allowing them to detect food hidden in densely forested areas.

Old World and New World vultures perform the same important ecological role, but they are not closely related. Instead, these two groups evolved many of their scavenging adaptations independently, developing similar lifestyles and behaviours despite arising on different continents.

One fascinating difference is how they find their food. Old World vultures have exceptional vision, allowing them to spot potential meals from incredible heights. New World vultures, on the other hand, have a much stronger sense of smell, which can help them locate food in dense forests where visibility is limited.

A group of vultures circling together in the air is called a kettle, and watching one can be an incredible sight. Here in Southern Ontario, September offers some of the best opportunities to observe large kettles of vultures. Turkey vultures are a familiar and welcome migratory bird in Ontario, providing an important ecological service by consuming carrion in both urban and rural landscapes throughout the warmer months. They typically arrive in the province in early spring and remain throughout the summer breeding season before heading south again in the fall. Large kettles of turkey vultures are often seen during autumn migration, circling together high overhead. Because they rely on rising columns of warm air, known as thermals, to stay aloft, migration often takes place on sunny days with favourable weather conditions. Next spring, they will return to Ontario to breed, completing a journey that may span thousands of kilometres.

How Can You Help?

Despite their incredible adaptations and important ecological role, vultures face serious conservation challenges, and several species are at risk of becoming extinct in the wild.

International Vulture Awareness Day gives us a chance to see vultures in a new light and recognize the value they bring to our ecosystems.

So the next time you see a vulture soaring overhead, take a moment to appreciate what you’re seeing. It’s one of the most specialized birds on the planet, helping keep the natural world clean, healthy and in balance.

One of the simplest ways to help is to learn about vultures and share what you learn with others. Raising awareness is an important part of changing perceptions and encouraging support for organizations working to protect vultures and their habitats.

You can also learn more about these fascinating birds “On Safari!” when you visit our Birds of Prey Conservation Centre and join us for our daily educational Birds of Prey Flying Demonstration.

This International Vulture Awareness Day, let’s give vultures recognition they deserve and celebrate the important job they do every day.
