Birds
By Michelle Anderson and Carly Poesch
Phylum Chordata
Subphylum Vertebrata
Class Aves
Habitat
• In time, birds have
adapted to live in
diverse regions
including: Forests,
mountains, deserts,
oceans, marshes, and
many more
Food Source
• Early in earth’s
history, birds ate
animal food, but seed
eating came later
• They now eat almost
everything including:
Nectar, roots, grass,
and seeds
Importance to Humans and
Environment
• Birds that eat other
animals or, predator
birds, have an important
role in the food chain.
• They keep rodents
under control, helping
farmers.
• Birds help stop the
spread of some diseases.
• Birds spread pollen and
seed to help
reproduction of plants.
Unique Characteristics
• For a 170 lb. man to exert
as much energy as a bird,
he would have to eat 285
lbs of hamburger or
double his weight in
potatoes.
• Some birds have
hollow bones to make
them lighter, so they
can fly.
• Some birds can
maintain a body temp
of 40 degrees Celsius
even on cold winter
days
Skeletal/Support System

Respiration
Click
Here
• Birds need a steady
stream of oxygen to
fly, and to be able to
release large
amounts of CO2
• The respiration cycle
of a bird is much
more effective than a
mammals,
transferring more air
with each breath
• Basically, birds
breath in and out at
the same time
Respiration
Reproductive System
• 95% of birds are socially
monogamous, they pair
with one mate for at least
the length of the breeding
season.
• Cloaca is the
reproductive organ in
birds.
• Eggs are fertilized and
given nutrients inside the
female before the hard
shell forms.
Sensory/Nervous system
• Birds are very intelligent,
they must fly at high
speeds, catch prey from
long distances, and
migrate thousands of
miles.
• This demands lots of
gathering and processing
information
• Bird senses are more
advanced than humans.
• Birds have great vision,
but taste and smell are
not as well developed.
Sensory System-Migration
• Birds have a sixth
sense-to migrate
• It is a magnetic sense;
like an internal
compass
•Some few birds, do not
have this sense and have
learned to use the stars for
migration
Circulatory System
• Birds have a closed
circulatory system.
• A Closed Circulatory
system is a blood
circulation system in
which blood moves
through the body in
closed vessels.
Excretory System
• Bird’s waste systems are
much like reptiles
• Waste is removed from
blood from the kidney
• Then converted to uric
acid and put in the
cloaca
• There water is absorbed
and bird droppings are
formed

Bird Flight
Feathers
• Feathers are an
adaptation that has
enabled them to
become successful.
• Birds have been
around since the time
of the dinosaurs

Beak Adaptations
• The beaks are
adapted to the kind of
food the bird eats.
• The toucan has a
large, strong beak to
slice food
• The long beak of a
pelican is ideal for
getting fish
Bird Feet
• Birds have hind limbs
used for walking,
swimming, running, or
perching
• Front limbs have
modified into wings
Endotherms
• Definition of
Endotherms: The
heat from within
• The bird’s body is
insulated enough to
conserve most of its
metabolic energy.
• They can maintain a
constant high body
temp

Orders
• There are 27 orders
of birds
• More than ½ are
Passeriformes, which
include house
sparrows and
perching birds
• StruthionifrmesOstriches
• Casuariiforms- Emus
