Meleagris gallopavo
          Turkey Facts
• 5,000-6,000 feathers cover the body
  in patterns called feather tracts
• Feathers keep turkey dry & warm
• Allow them to fly
• Allow them to show off for opposite
  sex
• Head & upper part of neck is
  featherless
• Feathers exhibit a metallic glittering
  called iridescence
• Feather colors vary from red to green
  to copper to bronze to gold
• Male is more colorful
• Female is drab brownish to lighter
  color to help camouflage with
  surroundings
• Male turkey is called the gobbler
• Female turkey is called the hen
• Two major characteristics that
  distinguish males from females, Spurs
  & Beards
• Males begin growing spurs soon after
  birth
• Spurs can reach up to 2 inches long
• Beards are modified feathers growing
  out of chest
• Beards grow to an average of 9 inches
  long but can grow much longer
• 10-20% of hens will have beards
• Have excellent vision during the day
• Poor night vision
• Very mobile
• Turkeys can run up to 25 mph
• Turkeys can fly up to 55 mph
• Mating season can occur between
  February & April
• Hens nest in shallow dirt depressions
  on the ground
• Hens lay a clutch of 10-12 eggs during
  a 2-week period, usually laying one egg
  per day
• Hens will incubate eggs for about 28
  days, occasionally turning &
  rearranging the eggs until they are
  ready to hatch
• Newly hatched flock must be ready to
  leave the nest within 12-24 hours to
  feed
• Young turkeys are called poults
• Poults eat insects, berries & seeds
• Adults will eat anything from acorns
  & berries to insects & small reptiles
• Usually feed in early morning &
  afternoon
• Like open areas for feeding, mating &
  habitat
• Forested areas are used as cover from
  predators & night roosting sites
• A varied habitat of both open &
  covered areas is essential for wild
  turkey survival
• Pittman-Robertson Act helped restore
  wild turkeys & habitat
• The rocket net allowed wildlife
  agencies to trap & relocate wild
  turkeys
• From 30,000 in the early 1900’s to
  over 7 million today
• Turkeys cannot overpopulate an area
  and strip it of available food since
  their diet varies
• Gobblers will mate with multiple hens
  in a season or day
• An abundance of hens can allow a
  population to recover from poor hatch
  years in as few as two years
Predator-Prey Relationship
• Survival of the fittest
• Fit individuals maintain a healthy
  breeding population
• Turkey nests are the main target of
  predators
• Snakes, skunks, opossums, raccoons,
  rodents, dogs, coyotes & crows prey on
  nests of turkeys
• About ½ of turkey nests make it to
  hatching
• Poults fall prey to hawks, owls, foxes
  & bobcats
• Few adults are taken by predators
  except in situations where the adults
  are in poor health
              Habitat
• Habitat quality also determines how a
  species will survive predators
• Early successional plant stages
  provide shelter for poults & nests
• Habitat quality & distribution is more
  important than the number of
  predators
     Turkey Information
• Largest of the North American game
  birds
• Adult males weigh between 16 & 24
  pounds
• Adult females weigh between 8 & 10
  pounds

  weighed 37 pounds
             Feathers
• Males: Iridescent red, green, copper,
  bronze & gold feathers
• Toms use bright colors for attracting
  females during breeding season
• Females: Drab, usually brown or gray
  feathers. Allow hens to camouflage &
  hide while nesting
           Color Phases
• 4 basic color phases
• Smokey gray color phase
• Melanistic color phase (all black)
• Erythritic color phase (reddish
  coloration)
• Albino color phase (very rare)
                Head
• Males: brightly colored, nearly
  featherless; during breeding season
  the head color will change between
  red, white & blue, often in a few
  seconds
• Females: gray-blue with some small
  feathers for camouflage
• Carnucles: fleshy growths on the
  heads of males & females
• Snoods: fleshy protrubances which
  hang over their bills & can be
  extended or contracted at will
• Male snoods is much larger than
  females
• Unsure of what the snoods are for but
  believed to be developed as a way to
  attract mates
               Beards
• Cluster of long, hair-like feathers
  grown from the center of the chest,
  known as a beard
• On males, the average beard is 9” long
• 10-20 percent of hens will grow
  beards
• Longest beard on record is more than
  18” long
                Legs

                 Tail
• Usually 12-15 inches long & banded at
  the tips
• Color bands will vary by subspecies
• Males will fan their tails to attract a
  mate
• Adult males can be distinguished from
  juvenile males by the length of tail
  feathers
              History
• Early 1900’s most wild turkey
  populations had been wiped out due to
  habitat destruction & commercial
  harvest.
