 Coot |
The American coot is a slate-gray, duck like bird.
Its bill is white with a dark reddish ring just
before the tip. The frontal shield, an extension
of the bill into the forehead, is also white with
a reddish oval near the tip that is visible at
close range.
American coots are excellent swimmers and divers.
Although it swims like a duck, the American Coot
does not have webbed feet like a duck. Instead
of having all the toes connected by webs, each
coot toe has lobes on the sides of each segment.
American coots prefer to live along open ponds
and marshes as well as coastal bays and inlets.
Coots prefer to nest in weedy freshwater marshes
and wetlands but assemble in large flocks on both
fresh and salt water in winter. Building their
nests on shallow platforms using dead leaves and
stems, the American coot lays eight to 10 pinkish
eggs with spots of brown.

 Pigeon |
Pigeons existed long before humans. They
originated several million years ago in Asia and
now pigeons are found throughout all of the United
States and Canada in almost all metropolitan areas.
Pigeons are gregarious and tend to be found in
small groups; around twenty to thirty birds.
They eat seeds and grains but they are willing
to sample just about anything.
Pigeons reproduce throughout the year and can
raise four or five broods annually. The female
usually lays two white eggs. Both parents take
turns keeping the eggs warm. Males usually
stay on the nest during the day and females at
night. Incubation takes about 16 to 19 days
and the young are fed crop milk for about the
first two weeks.
There are as many as 28 pigeon color types.
Pigeons have colorful, iridescent neck feathers
which are called a "hackle." Adult
males and females look alike, but the male hackle
is more shimmering than the female’s. In
addition, pigeons have many types of feathers
some that look like hairs. These feathers
may have sensory functions, such as detecting
touch and pressure changes. Adults have orange
or reddish orange eyes. The young ones that
are less than six to eight months old have medium
brown or grayish brown eyes.
Pigeon eyesight is excellent. Like humans,
pigeons can see color but they can also see in
the ultraviolet spectrum. Pigeons can hear sounds
at much lower frequencies than humans can such
as wind blowing across buildings and mountains,
distant thunderstorms and even far away volcanoes.
Sensitive hearing may explain why pigeons sometimes
fly away for no apparent reason.
Pigeons can fly up to 40 or 50 miles per hour
and may fly as far as 600 miles a day. They
seem to be able to detect the Earth’s magnetic
fields. This magnetic sensitivity, along
with the ability to tell direction by sun, seems
to help pigeons find their way home.
Although pigeons are considered by many to be
dirty and disease ridden, there is little evidence
linking pigeons directly to infections in humans.

 Duck |
Mallard Ducks possess a green head and yellow
bill thought to be the most abundant and wide
ranging duck on Earth. Mallards prefer calm, shallow
sanctuaries, but can be found in almost any freshwater
across Asia, Europe, and North America. They are
also found in saltwater and are commonly found
in wetlands.
The male, or drake, is typically colored while
its green head sits atop a white neckband that
sets off a chestnut colored chest and gray body.
Females are a dappled brown in color with shimmering
purple blue wing feathers that are seen as a patch
on their sides. Mallards can grow to about 26
inches in length and can weigh up to 3 pounds.
Mallards usually head dip or completely upend
in the water to seek and catch their food. They
spend most of their time near the surface and
look for invertebrates, fish, and amphibians.
They also eat grains and plants.
Mated pairs travel to and breed in the northern
parts of their domain and build nests on the ground
or in a protected hollow. They normally lay about
a dozen eggs, and the incubation period lasts
less then a month. Mallards are territorial during
this time, but once it’s over males leave the
nest and join a group of other males.
Most mallard species are common and not considered
threatened. However, one threat to their population
is hybridization with other ducks.

 Swallow |
Swallows are small birds with long and pointed
wings. They are fast masterful flyers which catch
all their insect food on the wing. Their legs
and feet are diminutive, not fit for walking,
and their bills are very small. Their outer V-shaped
tails represent their longest feathers. Swallows
are usually seen perched on wires or flying over
water, often in large flocks. They are colonial
nesters.
Swallows are beneficial birds in that they consume
large quantities of insects. Different species
of swallows prefer different types of insects.
For example, the purple martin typically eats
dragonflies, moths, and butterflies. Barn swallows
consume large flies, and when the weather is bad
they eat other insects off the ground. Besides
insects, the Tree swallow eats a variety of seeds
and berries.
Swallows come back to the same nests year after
year. Swallows repair old or damaged nests which
can last for many years. Old nests in good condition
are taken over by new family.
An average swallow lives about four years. Swallows
usually stay with the same mate for life. In some
cases, the male swallow helps incubate and care
for the hatchlings. This mainly occurs when swallows
are living in colonies otherwise the female cares
for the young. Both the male and the female feed
the hatchlings.
These birds are truly useful in controlling the
insect population. Providing nesting boxes and
adequate housing is a great way to attract swallows
to your property.

 Starling
|
Starlings are widespread throughout all of North
America and are common in cities.
Starlings belong to the family of birds which
includes vocal mimics known as myna birds. Starling
song is quite complex including a series of whistling
notes, chatter, and a clear “wolf” whistle.
Starlings are expert at exploiting urban, suburban
and agricultural areas. They are one of only a
few birds that live among the heavily human populated
areas and disturbance.
Starlings have wide range of food tolerances
though they prefer insects. They often descend
on lawns consuming insect pests and commonly seen
around dumps, landfills, and many specialize in
picking through open dumpsters and trash bags.
Male and female starlings look similar. Both are
glossy black with purplish and greenish markings
on the head, back and breast. They lose their
feathers in the fall and obtain new feather tips
that are whitish giving the bird a speckled appearance.
Starling beaks are yellow during the spring but
by fall it becomes brown. Their beaks are short
and are designed to open with force. The strong
opening beak is an adaptation for probing in the
soil for insects and worms, pushing rocks and
soil out of the way.
Starlings are monogamous; they court and mate
in the early spring. Most of the spring and summer
is spent by paired birds in nesting and raising
young anywhere from three to eight eggs are laid
in each clutch. Adults can nest three times a
year. The young fledge at between two and three
weeks of age.
Large groups of starlings have been known to
join with grackles and blackbirds at certain times
of the year and can cause serious problems to
agriculture. The biggest issue with starlings
in urban and suburban areas results from their
nesting habits. Starling nests built into any
house can accumulate material that is unsightly
and could present a fire hazard. Starlings do
not remove material from the old nests but keep
adding to them year after year. Starlings cause
complaints by getting into trash and getting stuck
in chimneys and metal flues.

 Sparrow |
House sparrows are intelligent birds that roost
in noisy flocks on branches of trees and bushes,
ivy covered walls, under eaves of houses, attic
vents and commercial signs.
The house sparrow is a small but stocky bird 5.5
to 6.5 inches in length. The male can be distinguished
from all common sparrows by its black throat,
upper breast and ash gray crown as well as a chestnut
colored cape extending from the eyes along the
side and back of the neck.
House sparrows are a social bird, nesting closely
to one another and flying and feeding in small
flocks. Nests of any easily obtained material
are built on almost any likely high place. Sparrows
raise at least two and up to five broods per year.
Three to eight eggs are laid per clutch taking
an average of two weeks to hatch. The annual mortality
rate of mature house sparrows has been calculated
at 54%.
Sparrows eat seeds and grains; including young
seedlings, buds, flowers, as well as fruits, vegetables,
human table scraps, and insects. The house sparrow
has become somewhat dependant on humans for both
food sources and nesting sites.
House sparrows have been implicated in the transmission
of more than 25 diseases to humans and domestic
animals including psittacosis, salmonellas, and
several forms of encephalitis. In addition, house
sparrows are often a nuisance in urban facilities
like manufacturing and food processing plants.
Gutters and drainage pipes clogged with sparrow
nests can backup and cause extensive water damage
and fires have been attributed to electrical shorts
caused by machinery housing sparrow nests. Lastly,
feces buildup can lead to structural damage from
the uric acid in droppings, plus the bacteria,
fungal agents and parasites in the feces also
pose a health risk.

 Black
Bird |
The common blackbird is spread throughout Europe,
northern parts of Scandinavia, Asia, and northwestern
Africa. These birds live in parks, woodland areas,
cemeteries and are also often seen in gardens.
They generally prefer wet places. Their nest is
usually cup-shaped and located in a tree, bush,
or on a house. Nest materials include twigs, sticks,
grass, and leaves which are all affixed with mud.
Turdus Merula is approximately 11.5 inches long.
The male, or cock, has a jet black colored plumage
with yellow-orange bill. The bill is darker during
winter time. The females, or hens, are dark brown
and have a brown bill. The young have similar
plumage to the hens but the bill is yellowish.
These birds do not live in flocks but sometimes
can be seen in pairs.
Blackbirds can be recognized by their strong voice;
they have a large variety of voice types. The
blackbirds eat invertebrates, earthworms, snails,
and slugs easily found in wet conditions. They
also eat berries and a variety of fruits such
as cherries, grapes, etc. The hens have from three
to seven greenish-blue eggs with reddish-brown
markings. The hatching lasts 13-14 days and the
offspring are fed by their parents for another
14-15 days.

 Crow |
Crows can be found just about anywhere in North
America. They thrive in mountains, woodlands,
across plains and farmers' fields, and urban areas.
Crows are not very social creatures while raising
their young. However, they will form a large group
to travel to south in the fall. Crows are generally
black with black beaks and legs, but they can
also be black with white, gray, or brown coloring.
The common crow is about 20 - 30 cm long with
a wingspan double that.
Crows nests are bulky structures built in trees
or bushes. They are made of twigs, lined with
bark, grasses, and rootlets. The female crow lays
four to seven eggs and the male helps incubate
them. These eggs are greenish or bluish and blotched
with brown. Once hatched the young stays in the
nest six to eight weeks and in their early life
they eat almost half of their body weight per
day which the parents bring to them.
Crows are omnivorous; they will eat anything.
Their diets include animal and vegetable matter,
insects, crops especially corns, and the eggs
or young of other birds. Despite their bad reputation
for eating crops, crows also eat a number of pests
which are harmful to those same crops including
cutworms, wireworms, grasshoppers, and even noxious
weeds.
In some areas, crows are regularly shot for damaging
agriculture. Scarecrows, cats, and many other
tactics have been used to keep them away, but
they are intelligent birds and can quickly outsmart
most traps. Any scarecrow which remains in the
same place for several days quickly becomes a
perch rather than a warning sign.
