Turkey (Cathartes aura) and black (Coragyps atratus) vultures are both inhabitants of Virginia. Vulture damage can be grouped into two gross classifications of urban/suburban damage and livestock damage. Both the turkey vulture and black vulture are classified as migratory birds are therfore protected by the Migratory Bird Treaty Act.

Turkey or black vultures or both vulture species may occupy roost sites in urban or suburban areas where they conflict with people. People tend to have health concerns about these roosts due to excessive accumulations of fecal droppings, concern for the health of children and pets who may be exposed to bacteria or viruses in vulture fecal droppings or vomit. Damage caused by turkey or black vulture roosts include loss of use of the property, the over-powering ammonia odor emanating from the roost site, death of ornamental trees from acidic fecal droppings or excessive limb breakage, and the aesthetically unappealing white-wash effect from fecal droppings on lawn furniture, the home, walkways, vehicles, and the yard. Damage concerns often associated with live stock are predation by black vultures and disease transmission but both species.

In Virginia vultures are a protected non-game species. In addition to state non-game laws vultures are also federally protected under the Migratory Bird Treaty Act. The Virginia Department of Game and Inland Fisheries shares regulation authority over vultures with the United States Fish and Wildlife Service. At no time is it legal to use lethal force on vultures without first obtaining a permit from both the Virginia Department of Game and Inland Fisheries and the U.S. Fish and Wildlife Service.

Virginia Laws

In Virginia it is illegal to

It is a Federal offence to

  • possess, sell, deliver, carry, transport, or ship any vulture or vulture part since they are classified as a migratory species. (Migratory Bird Treaty Act)

Life History

Two species of vultures are present in Virginia: turkey vulture (Cathartes aura) and black vulture
(Coragyps atratus). Vultures are in the family Cathartidae and are related to storks and egrets.

Turkey vultures are large dark brown birds with wing spans up to six feet and weigh about four
pounds (NWRC, unpublished data). Distinguishing characteristics of turkey vultures are a bright
red head on adults, the leading edge on the underside of the wing is black while the trailing edge
is gray, and the long tail extends well beyond the body when in flight (Peterson 1980). Turkey
vultures have been reported to live to 16 years of age (Henny 1990). In contrast, black vultures
have less than a five foot wing span and average 4.6 pounds in weight (NWRC, unpublished
data)(Peterson 1980). Adult and juvenile black vultures have dark grey heads, the body is black,
the underside of the wings are dark grey to blackish with white splotches at the end of the wing,
and the tail is relatively short (Peterson 1980) giving the appearance of a large bat when flying.
Black vultures have been reported to live to 25 years of age (Henny 1990). The mode of flight
between black and turkey vultures differ due to different wing lengths supporting about the same
body weight (Rabenhold and Decker 1989). Turkey vultures flap the wings a few times and glide
when at low altitudes, whereas black vultures must flap constantly interspersed with brief glides
when at low altitudes unless a strong wind blows. At high altitudes both vultures fly by primarily
gliding and riding thermal wind currents.
Black and turkey vultures generally lay 2 eggs which are incubated for approximately 40 days
(McHargue 1981). The young are fed and cared for by the adults for two to three months before
fledgling (Jackson 1983). A post fledgling dependency period where adults lead young to food
may exist for vultures (Rabenhold 1987, Jackson 1983). It is believed that vultures nest annually.

Ecology
Turkey and black vultures are obligate scavengers (Rea 1983, Coleman and Fraser 1987). The
diet consists of carrion, fish, and invertebrates (Rea 1983, Rabenhold 1987, Coleman and Fraser
1987). However, black vultures will kill other animals and tear the animals apart for food (Roads
1936, McIlhenny 1939, Sprunt 1946, Lovell 1947, 1952, Parmalee 1954, Mrovsovsky 1971,
Lowney 1999).
Vultures roost in communal roosts, especially during late fall through early spring since this
behavior enhances the ability to find food. Roosts may number as few as 15 birds to over 1,000
(Prather et al. 1976, Lowney and Eggborn, unpublished data, J. Fraser, VPI & SU, pers.
commun).
In North America, black vultures occur in the southeastern United States, Texas, Mexico, and
parts of Arizona (Wilbur 1983). Black vultures have been expanding their range northward in
the eastern United States (Wilbur 1983, Rabenhold and Decker 1989). J. Bucknall (USDA, pers.
commun.) reported black vultures living in New Jersey and Pennsylvania in 1995. Black vultures
are considered locally resident (Parmalee and Parmalee 1967, Rabenhold and Decker 1989),
however some populations will migrate (Eisenmann 1963 cited from Wilbur 1983). Turkey
vultures occur in all of Mexico, most of the United States, and in the southern tier of Canada
(Wilbur 1983, Rabenhold and Decker 1989). Also, turkey vultures continue to expand their
range into the northeastern United States (Wilbur 1983). Northern populations of turkey vultures
migrate from summer to more southern wintering areas (Stewart 1977).

Disease

There are many diseases that wildlife species are capable of carrying and transferring to humans (zoonotic diseases). While all zoonotic diseases are a serious threat to humans this website will only address those that are a concern for Virginia residents.

The Center is not aware of any diseases of concern that are transferable from vultures to humans.
