3. FOR FOOD
 Birds are the prime source of food for humans. They produce eggs and
also meat. There are many types of birds used for meat purposes like
turkey, hen, ducks, geese, quails, etc.
 The meat of birds is consumed as a daily food in many countries,
depending on the type of bird available.
 Their meat is called white meat and unlike red meat (beef or mutton). It is
said to be healthier for the heart as it has a less fat content. Even those
with the risk of obesity and cardiac problems can also eat it.
 Further, the eggs are part of daily meals, cakes, ice creams even among
vegetarian countries. Unlike vegetarians, some eggetarians refrain from
eating meat but eat eggs.
 Eggs are rich in protein and hence advised for consumption by patients
suffering from debilitating diseases.

4.  Birds are grown to make monetary gains through
business. They are raised for their meat and eggs.
They are economically very viable for poultry farmers.
As they contribute to food, the poultry business seems
to be evergreen without losses unless affected by
diseases.
ECONOMIC
CONTRIBUTION

5. IN AGRICULTURE
 Birds are not directly employed by a man in agriculture. But they
naturally serve some benefits like
 a) Pollination: Birds help in cross-pollination. They carry male
gametes of one plant and drop them on to female gametes of
another plant. Thus they help in sexual reproduction plants. Besides
birds, even the insects and wind serve the purpose. But birds play a
prominent role. Cross-pollination helps in the formation of healthy
seeds.
 b) Fertility: Birds excreta is rich in uric acid. This can readily convert to
ammonia and acts as fertile manure to plants. The birds around the
farm may contribute less to the manure. But the waste from poultry, if
added to the soil, dramatically enhances fertility.
 c) Pest control: Birds rely on insects and their larva to feed
themselves and their babies. So during crop season, there is extensive
growth of insect population due to favorable conditions. Birds keep the
growth under control and help the crop from pest attack.
 d) Rodent control: Unlike insects, rodents are a big problem for
plants. Rodents eat away the yield of the crop. Birds like eagles keep
an eye on these rodents and carry away for consumption. Thus they
keep the rodent growth under control, which in turn helps the farmers.

6. COMMUNICATION
 When the man did not have a phone or automobiles for his
transport, birds were widely used for communication. Pet birds
like pigeons, parrots were used to communicate with distant
people. They were used to deliver small letters tied around
their neck to nearby villages and towns.
 This mode of communication was a swift, reliable, and
inexpensive method. Since the family had some birds, they
could communicate with their relatives by using them.

7. FOR HUNTING
 Birds like eagles are used for hunting wild animals
like foxes, rabbits, etc. The owner of the bird
releases it to catch a running animal. The birds
swiftly fly in the air and attack the animal and
arrests it so as its owner takes the prey.

8. COMPETITION GAMES
These are banned in most parts
of the world. Here hens,
especially males, are allowed to
fight for fun and gambling. This is
a cause of violence for the birds.
So many governments banned
bird fights.

9. FOR COMPANY
 Birds are grown as pets by many. They help one
avoid loneliness and provide a company. Even we
come across many stories where the birds help in
tracking the culprits of mischief, and some birds
also speak, etc.

10. BEAUTY OR ATTRACTION
 Birds are also kept for increasing the appeal of
premises. In places like hotels, exhibitions,
recreation centers, etc. They are easy to maintain,
as they require less food and water.

11. IMPORTANCE OF BIRDS IN NATURE
 Birds are part of Nature. They contribute to the ecosystem and environment.
They help follow ways to Nature.
 1. Food chain
 Birds are part of the food chain. They are carnivores here. They keep a check
on the overpopulation of rodents, insects and even snakes. Small birds, in
general, eat up insects and their larva. While large ones like eagles hunt and
kill rodents and snakes (reptiles) for food.
 2. Scavengers
 We might have come across birds circled a corpse of animals. Even in a forest,
once an animal is left out by lions and tigers, the rest is consumed by birds.
Birds are natural scavengers. They help keep the Nature clean of dead and
decay matter. Even they do not leave out grains or fruits which are thrown out
into open places.
 3. Seed propagation
 Birds are the key to seed propagation. Hence we see plants growing
spontaneously at different locations on the soil. The birds eat the fruit or seeds
of the plants. Some of them remain undigested and get excreted as such.
When these seeds reach the ground, they can germinate in favorable
conditions. Thus birds help in natural seed dispersal and plant propagation.
 4. Beauty to Nature: Birds are some of the creatures which add charm to
the environment. Hence we see much painting with birds and even
photographs of birds to reflect beauty.

DISEASES
AS THREAT OF AIRCRAFT
BIRDS AS A PEST

13. AS DISSEMINATORS OF DISEASES
 Birds are suspected to disseminate viruses of certain
diseases like the Kyasamer Forest Disease (K.F.D.)
of Mysore, work on which is going on at the Virus
Research Centre, Poona in collaboration with the
Bombay Natural History Society.
 HISTOPLASMOSIS disease is generally found to
develop around old chicken houses. Its pathogen
Histoplasma capsulatium prefers undistributed litter
in and around old chicken houses or in undistributed
droppings under Birds-roosts. The spore of the
causative organism lodge in the lungs/liver/spleen of
Man/Dog/Horse etc.

14. AS THREAT OF AIRCRAFT
 Different species of birds are great menace to the
Aeroplanes. They are responsible for several
collisions and air crashes of Civil and Military Air
crafts.
 Vulture and kites cause damage by directly striking
against the air craft while the small ones do so by
getting sucked into air intake of the Jet Engine.

15. BIRDS AS A PEST
 Birds are the pest of Many Crops.
 For example : Parrots eat and cut the Ripe and Semi-
ripe fruits and thus cause heavy damage to various
Horticulture and Agriculture crops. e.g., Maize, Juar,
Wheat, Guava, Mango and Cashew fruits also.
 Parrots have a habit of flying in flocks and alighting
on crops in flocks.
