Listen!
A strange gobbling sound booms across a meadow early on a spring morning. Tails fanned wide and heads held high,
stocky males strut proudly to attract their mates.

Ups
and Downs
In
colonial days, wild turkeys were common in North Carolina. But by 1970, due
to decades of unrestricted hunting and the elimination of original forest habitats,
turkey numbers had plummeted to only about 2,000 birds. During the past 30 years,
regulation of hunting, management, restoration of habitat and stocking
of turkeys in unoccupied habitats have brought wild turkey populations back.
More than 100,000 birds now inhabit all 100 North Carolina counties from the Mountains to the Coastal Plain.
Wild
turkeys have 28 different calls, each of which has a different function or carries a different message.
Habitat
Selection
Wild turkeys
are very adaptable and can survive in a wide variety of habitats. Habitats combining some open area and forests that vary in age are used most often. Social behavior and seasonal differences in food requirements determine habitat changes from season to season.
Turkeys
are opportunistic omnivores; they eat a variety of plants and animals including mast, buds, fruits, grasses,
seeds, green vegetation, insects, snails and other small animals. During winter, hardwood forests with oaks, hickories and beech trees are heavily used by turkeys because they provide
hard mast. In the spring and summer, fairly open habitat with thick herbaceous vegetation on the ground is preferred for nesting. Once poults hatch, hens move broods to areas with vegetation that supports high insect populations. In late summer and early fall, turkeys feed in a variety of habitats plentiful in both hard and soft mast.
Nesting
In North
Carolina, turkeys begin nesting from mid April through mid-May. Nests are on the ground, usually close to a tree, stump or bush. The hen chooses an area where she can see all around while sitting on her nest and can move on and off the nest easily. On average, a turkey hen lays 12 eggs that she incubates for 28 days. Poults are precocial but remain flightless for 14 days after hatching.
These days of flightlessness are
when most turkey deaths occur.
Raccoons, foxes, bobcats, hawks, owls and snakes all prey on young turkeys. Even
uncontrolled feral or freeranging domestic dogs and cats can prey heavily on turkey nests and poults. Wild predators are seldom a limiting factor on turkey populations, but about half of all turkey nests
are lost each year
to abandonment or predation. However, turkeys have evolved as a prey species and
overcome high annual death rates by beginning to reproduce at a young
age and by laying a large number of eggs each year. This means that turkeys have
a high reproductive rate.
During
their first few months of life, poults feed heavily on insects, which are high in protein and provide nourishment needed for rapid growth.
Disturbance
is a critical factor in determining whether turkeys use an area. Turkeys are highly mobile and secretive. Frequent disturbance by human activities will often result in abandonment by turkeys of an otherwise perfect habitat.
Social
Structure
Turkeys have
a highly developed social structure that changes seasonally. Single-sex
winter flocks break up in the early spring as breeding season begins.
During the breeding season, temporary groups with turkeys of different
ages and sexes are common. Outside of the breeding season there are four
basic types of wild turkey flocks. In summer and early fall, family flocks include
hens with poults. Adult and juvenile hens from these family flocks often
remain together throughout the winter. Hens that have been unsuccessful in nesting
form adult hen flocks. Adult gobbler flocks are made up of male turkeys over one year in age. Juvenile gobbler
flocks are formed in late fall when young males leave family flocks.
What
Does It Mean?
opportunistic
omnivore: an animal that feeds on both plants and other animals depending
on their availability
mast:
seeds and fruit produced from trees and other woody
vegetation.
Hard mast includes acorns, hickory nuts and other
hard
seeds. Soft mast is produced from plants like blueberries,
blackberries,
wild cherries, pawpaws and dogwoods
herbaceous
vegetation: plants that do not develop woody tissue and die back at
the end of each growing season
poult: a
wild turkey chick from the moment of hatching until it is 4 weeks of age
brood: the
group of birds that hatch at the same time from an individual nest
precocial:
highly independent at the time of hatching
feral:
a state of wildness found in free-ranging but once domesticated animals
limiting
factor: a condition that prevents a population of animals from increasing
to their fullest potential
evolved: developed under environmental pressures over many generations
reproductive
rate: the annual rate at which a population produces young

Get Outside!
Look for
turkey sign: With turkeys again distributed across the state, it is fairly easy to find a tract of federal, state or private
land that holds a flock of wild turkeys. In the winter look for circular scratching
on the ground where turkey have searched for food. Also, look for turkey tracks and feathers. Although turkeys are often
difficult
to see themselves, their sign should be easy to find in an area with an established population.
Listen
for a wild turkey gobbler: Identify a tract of land with an established turkey population to which you can gain access early on a spring
morning. If you are out before daybreak, you should be able to hear a turkey gobble just at daybreak as the other birds begin to call.
If you think there are birds in your area, but you don't hear gobbling, try calling with a commercially available "owl hooter." They
can be used to stimulate turkeys to gobble. But remember, peaks in turkey gobbling in the spring correspond to turkey
hunting season. Always get permission from the landowner before
entering anyone's property and be mindful of local turkey hunters.
