Biodiversity of Alabama:
100 Species to Know
Common Terrestrial Species
1. Turkey Tail
•
•
Type of shelf fungus, common on rotting trees in
forests
Fungi are saprophytes, they get nutrients from dead,
decaying things, important to recycle nutrients in
ecosystems
Turkey for comparison
2. Lichens
•
•
•
Flat, crusty plant-like growth on rocks, bark of trees
Are a combination of algae and fungus living together
(symbiosis)
Good example of pioneer species – are the first to
grow on bare rock, or in disturbed areas
3. Cicada
•
•
•
•
young nymph lives underground, crawls out and climbs up onto a
branch
undergoes metamorphosis to emerge as a winged adult (like
butterflies)
some species emerge in large numbers after spending years
underground
makes loud noise in trees
Adult (after
metamorphosis)
Nymph
(young
cicada
after
crawling
out of
ground)
4. Fowler’s toad
Bufo fowleri
•
Common statewide in a variety of habitats,
including disturbed areas.
•
Breeds March to August, often in more
permanent aquatic sites than other toads.
•
Alabama’s most commonly encountered and
widely distributed toad; often seen on roads
•
Field marks: bumpy skin with brown spots
•
Toads do NOT cause warts in humans
NOTE: Many amphibian species are used as indicator species (defined as a
species that is so sensitive to changes in the environment that it indicates the
health of the entire ecosystem). Mutant toads, frogs have been found in
many places.
5. Green Treefrog
Hyla cinerea
•Common nearly statewide,
• Breeds April to August in
permanent aquatic habitats
with emergent vegetation.
•Field marks: bright green
color with white stripe down
side,
•Treefrogs have sticky toe
pads that help them hang
onto surfaces
6. Cave salamander
Eurycea lucifuga.
• Fairly common to common in caves of northeast AL
• Field marks: orange-red body with dark spots,

7. Scarlet Kingsnake
•
•
•
•
•
•
Lampropeltis getula holbrooki
Fairly common, but secretive and
nocturnal
Lives in burrows underground
and in rotten logs
Predator, but not venomous
“Red on black, venom lack;
red on yellow, kill a fellow”
May be confused with poisonous
coral snake
Eats small rodents, reptiles and
other snakes (hence, the name
kingsnake)
8. Rat Snake
Elaphe obsoleta
• Fairly common statewide.
• Large arboreal snake, may nest high in tree cavities, a position
that may reduce mortality from fire ants and other groundforaging predators.
• Known to many as “chicken snake” because it frequents chicken
houses for food
• Occurs in most terrestrial habitats, and occasionally may be
found in, or near, forested suburbs.
• Two subspecies with different colors:
– E. o. obsoleta (black rat snake) – north AL
– E. o. spiloides (gray rat snake) – more common in south AL
9. Eastern Garter Snake

rodents
10. Green Anole
Anolis carolinensis
• Common across AL except in extreme north due to cold

Antarctica) and in all 67 AL
counties, mostly widely distributed
land bird in the world
• Feeds on small mammals, lives
near farms, edges of woods, fields

wing feathers allow silent flight;
great hearing (facial feathers form
a “dish” and asymmetrical ears
improve sound reception)

downy feathers
27. Eastern Screech Owl
Otus asio
• Found in woodlands, especially
near open areas, and orchards

and adaptable

includes rodents, rabbits, birds,
eggs, many kinds of fruits,
domestic poultry, livestock,
garbage, pet cats and
watermelons
• Usually 6 pups per litter
• Looks like a domestic dog, but
with longer legs, more scruffy
30. Bobcat
Lynx rufus
• Common statewide in a wide array of
habitats including dense understory,
bottomland hardwood forests, swamps,
and farmlands.
• Breeding peaks December-April, but
young may be born anytime during the
year.
• Diet includes many kinds of vertebrates
and invertebrates.
• Behavior: crepuscular (active at dawn and
dusk)
31. Eastern Cottontail

• Primarily occurs in deciduous
forests and forest edges, but
also in grasslands, along
fencerows, and in urban areas
• Produces up to seven litters
averaging three to five young
annually
• Forbs and grasses comprise
most of diet in summer, but
consumption of twigs and tree
bark increases in winter
32. Nine-banded Armadillo
Dasypus novemcinctus
• Range expanded from Texas into southern US
since late 1800s, partly due to decreasing
numbers of large predators
• Armored carapace or shell is bone and horn
• Live in burrows
• Eat mostly insects
• Clumsy, slow movement
33. Opossum
Didelphis virginiana
• North America’s only marsupial
(young develop in mother’s pouch)
• Has a prehensile tail
• Omnivorous
• Sometimes they will “play possum”
and roll over, become stiff, and
their breathing will become slow
and shallow. This coma-like state
can last up to four hours. Some
predators will think the opossum is
dead and go away.
34. White-tailed deer
Odocoileus virginianus
• Flash of white on underside
of tail used to communicate
between deer when running
• Almost wiped out of
Alabama by early 1900s

few thousand, efforts to
restore population have
resulted in 1.75 million deer
by year 2000
• Important game animal
35. Red Fox
Vulpes vulpes
• Common in forested
habitats statewide.
• Diet: mostly small
animals, but may include
plants, eggs, and carrion

(3-9 pups)
36. Raccoon
Procyon lotor
• Successful generalist, found even
in urban areas
• Often associated with water
• Omnivore - consumes an
unusually wide range of plant and
animal foods
• The raccoon’s Latin name, lotor,
means “the washer” and refers to
the perceived habit of dipping food
in water before eating it. Recent
studies indicate that this behavior is
only common in captive raccoons
and seems to be a substitute for the
dabbling process used in searching
for prey in aquatic habitats.
