Do vulture effigies work?

At 4 of 8 study sites where vulture damage to property was a concern, damage was eliminated by hanging a carcass or effigy in trees where the vultures roosted.

What does it mean when vultures roost?

So, a young bird at a roost will follow an adult (apparently just because it is an older bird) to reduce its uncertainty about where to find food. Family members apparently also lead each other to food sources.

Behavior: The Turkey Vulture is gregarious and roosts in large community groups, breaking away to forage independently during the day. Several hundred vultures may roost communally in groups, which sometimes even include Black Vultures.

How do you use a vulture effigy?

What does a vulture roost look like?

Black Vultures roost in undisturbed stands of tall trees, as well as structures like electrical pylons. Roost sites are often close to water and next to obstructions that generate updrafts of air, to help the flock take flight in the early morning.

When you see a flock of vultures in flight, you’re witnessing a kettle of vultures. When you see vultures at rest in a tree or on a fence post, that’s a committee of vultures. And since vultures feed mainly on dead animals, when you see a group feeding, you’re in the presence of a wake of vultures.

How do vultures know when something is dying?

Surprisingly, though most birds lack any sense of smell , vultures can sniff out a dead critter from more than a mile away. “They smell the unique sulphurous chemical compounds of decaying meat from high in the sky, then will circle around downwards until they find the aroma’s origin,” Woterbeek said.

What are vulture effigies?

How do you dispersal vulture roosts?

Dispersal of vulture roosts near a livestock operation can help reduce the likelihood of depredations. Dispersal is often best accomplished by suspending a vulture carcass or taxidermic effigy in the roost, but other roost dispersal options, such as pyrotechnics, could produce a similar re- sult.

Why are vultures unresponsive to effigy in multi-species roosts?

Where vultures occupy mixed-species roosts with wading birds, cormorants, and anhingas, instal- lation of a vulture carcass or taxidermic vulture effigy has been ineffective. It is not clear why vultures in multi- species roosts are unresponsive to the effigy approach.

How did DDT affect the vulture population?

The pesti- cide DDT and its derivative DDE adversely affected vulture fecundity. The U.S. Environmental Protection Agency pro- hibited the use of DDT in 1972 due to negative environ- mental impacts to many animal species, and vulture popu- lations in the U.S. have grown steadily in the last 40 years.

How do vultures adapt to their environment?

Vultures clearly have adapted and thrived in the presence of human activity. Northern populations of turkey vultures migrate from sum- mer breeding areas to southern wintering areas. Black vul- tures are considered locally resident, but they engage in short term local movements in advance of bad weather.
