The presence of vultures around a home often sparks curiosity and sometimes concern. These large birds are a common sight in various environments. While their appearance can be unsettling, their presence is typically a natural occurrence rooted in their biology and ecological role. Understanding why vultures gather near human dwellings can help demystify their behavior and alleviate apprehension.
Vulture Species and Their Habits
North America is home to two common vulture species: the Turkey Vulture and the Black Vulture. Both species play an important role as scavengers, consuming carrion, which is the decaying flesh of dead animals. This dietary habit makes them nature’s clean-up crew, helping prevent the spread of diseases by removing carcasses.
Turkey Vultures are known for their exceptional sense of smell, detecting decomposition gases from over a mile away. This allows them to locate concealed carcasses. Black Vultures primarily rely on keen eyesight to find food and often follow Turkey Vultures. Both species commonly roost in large communal groups in tall trees or on structures like communication towers.
Why Vultures Gather Near Homes
Vultures are frequently drawn to residential areas for specific reasons, often connected to their scavenging habits and need for secure roosting spots. The most common attractant is the presence of dead animals, such as roadkill or deceased wildlife. Their efficient ability to locate these carcasses means even small, unseen remains can draw them to a property.
Residential areas can also offer suitable roosting sites. Tall trees, communication towers, water towers, and unoccupied buildings provide elevated perches for large groups. Black Vultures may roost on dark roofs during colder months, absorbing warmth from the sun. Less commonly, unsecured garbage, pet food outdoors, or discarded food scraps might attract vultures, though their primary diet remains carrion. Nesting in residential areas is rare but possible, often in secluded spots like abandoned structures or hollow trees.
Addressing Vulture Nuisances and Safety
While vultures are generally not aggressive towards humans or live animals, their presence can sometimes lead to nuisances. Large groups can cause property damage, particularly from corrosive droppings. Black Vultures have also been known to peck at rubber seals on cars or roofs, and damage roof shingles, window caulking, or pool covers.
Vultures are scavengers, not predators; attacks on healthy pets or people are extremely rare. They typically react defensively only if cornered or if their food source is directly challenged, at which point they may vomit as a defense mechanism. Vultures are federally protected species under the Migratory Bird Treaty Act. It is illegal to harm, harass, or kill them without a specific permit from the U.S. Fish and Wildlife Service.
Humane Vulture Deterrence
To discourage vultures from congregating around a property, several humane methods can be employed. Promptly removing any dead animals, securing trash cans, and avoiding leaving pet food outdoors can eliminate primary attractants. Trimming tall trees that serve as roosting sites can also make the area less appealing.
Visual deterrents like effigies of dead vultures, Mylar balloons, or reflective tape can be effective, especially for Black Vultures. Noise-making devices like air horns or clapping can help scare them away. Motion-activated sprinklers that spray water can also deter vultures from roosting areas. If these methods prove insufficient, or if there is significant property damage or large numbers of birds involved, contacting local animal control, wildlife rehabilitation centers, or USDA Wildlife Services is advisable. These professionals can provide further guidance and assist in obtaining permits for specific deterrence methods.
