While true buzzards are raptors native to the Old World, the word is often colloquially applied in North America to two related species of scavenging bird: the turkey vulture, found at least part of the year across the entirety of the lower 48 states, and the black vulture, a smaller but often more aggressive inhabitant of the American South and Southwest. While they perform crucial ecological functions, the birds can sometimes annoy homeowners when they gather for their nocturnal roosts in backyard trees.
Things You'll Need
- Motion-sensor sprinkler
- Bird distress calls
- Artificial dead vulture
- Taut line
Consider the situation carefully to determine whether the vultures are actually causing enough of a nuisance to warrant any action. The birds provide essential sanitation duties, processing carcasses in a region and thus reducing stench and other issues associated with more prolonged decomposition. If you can tolerate their presence, the vultures are likely to cause you no harm and repay your accommodation with a cleaner, more complete local ecosystem. But if the flock is making a mess or causing structural damage, investigate mitigation.
Install a motion-sensor sprinkler system to discourage roosting if you’ve determined the vultures must go. Several companies market such products, which can be erected on rooftops or in trees to spray vultures as they gather communally for the night.
Disturb the roost humanely in other ways to convince the birds another location will be less trouble. Shaking the roost tree from below, clapping and shouting, spraying a hose toward the canopy and playing the distress calls of other birds – available at pest-control outlets – are some options. Some people have success affixing helium balloons to the tree in question, though vultures are smart enough, over time, to see through such scarecrows. Firecrackers may do the trick as well but should be used only in compliance with local regulations. You may need to continue such routines several nights in a row to definitely encourage the birds to vacate.
Make or purchase the likeness of a dead vulture – believe it or not, such effigies are available, as from a taxidermist – and hang it from the roost trees where it may be easily seen by approaching vultures.
Contact a wildlife professional for advice at any stage. While a state or county wildlife or natural resources department may not be able to take any action against a vulture roost, staff can counsel you in your mitigation efforts.
