With all
properties, the potential damage from roosting birds
has to be considered. It is not just the mess,
inconvenience or health hazard, but also the
corrosive damage that can occur, particularly on
limestone buildings. Additionally, if anyone
is injured as a result of bird fouling from your
property, you are liable - so it pays to prevent.
Fouling of buildings
and monuments frequently occurs at places where the
birds nest or roost, this is not only unsightly, but
can also have a destructive effect as the acidic
droppings can erode the surface of stonework.
Gutters and drainpipes can get blocked, leading to
flooring and other problems. Even in domestic
buildings birds are a problem - not just for noise
and mess, but from secondary nest infestation or
mites.

Pavements can be unsafe
because of potential for slipping on droppings. Food
stored in warehouses and processing plants may be eaten or
contaminated and machinery and equipment fouled. Birds
can also be a potential transmitter of diseases such as
solmonellosis and psittacosis.
We can
remedy your bird infestation using the method most
appropriate to your needs - netting, bird spikes, or repellants.
We will then bird
proof and maintain your buildings to ensure the best
possible defence against future problems using the
latest materials and techniques ensuring an
effective solution and an unobtrusive finish, i.e.
nets, spring wire, pinnacle systems, gel, electric,
etc. at a competitive price.

Canadian Geese
A sure sign that those hot summer days are here is spotting family groups
out for a walk on the grass or a swim in a local body of water. This
sighting is not of a human family group, but a family of Canada geese,
consisting of a male, female and an average five to seven goslings, or
young. Fascinating to watch from a distance, Canada geese, Branta
canadensis, are extraordinary animals that have become common to the
Connecticut landscape. Often overlooked and frequently maligned,Canada geese
have some fascinating traits and provide yet another valuable insight into
nature.
One of the most common waterfowl, the Canada goose is found to live in or
at least migrate through, all of North America. If you have ever observed a
large flock of Canada geese, you may have noticed some differences amongst
them. Unbeknownst to many, there are actually 11 to 22 subspecies, or races
of Canada geese. There is one sub- species that does not migrate but remains
in Connecticut throughout the year.
Canada geese vary in size from 16-25 inches long with wingspans of 50-68
inches with weight that fluctuate from three to 14 pounds. These dark
grayish-brown geese have black tail and flight feathers, long black necks,
and patches of white found on their cheeks. The genders are usually hard to
differentiate, although the male is often a bit larger and defends the nest
while his mate incubates the eggs.
Often labeled herbivorous grazers as they feed extensively on tender, young
plants such as cattails, pondweed, grasses, clover, and other green shoots,
Canada geese do eat small invertebrates as well. Seen in ponds with their
head submerged underwater and tail sticking high out of the water, they are
feeding on various aquatic life such as insects, insect larvae, snails, and
small clams and mussels. Their glossy black bill has tooth-like serrations
on the edges, which helps them to strain food out of the water and to clip
plants that are growing in the ground.
Canada geese feed in open, grassy areas that provide easy accessibility and
good visibility to open water. Since they often walk to and from their
feeding areas, habitats with good clarity provide protection from predators
such as coyotes, bobcats, foxes, and humans. With an eye placed on each side
of their head, geese have a range of sight that circles almost all the way
around them; an aid them in spotting would-be predators and other invaders.
In the late spring and summer, this wide field of view is needed as parent
geese are on constant lookout for any intruders that may harm their young.
Not only do goslings have the same predators as their parents, but due to
their smaller size and inability to fly, they may fall prey to snapping
turtles, gulls, owls, and hawks. When still in the egg, skunks, weasels, and
raccoons may prey upon the nest.
Under the gander's watchful eye, the female goose makes a nest out of soft
plant material such as reeds and grasses. Once on the nest, she pulls the
soft, downy feathers from her breast to line the nest and begins to lay and
incubate her eggs. The gander, or male, staunchly guards his mate and their
eggs. She keeps the nest at a humid temperature between 100 -101 degrees F.
If the female leaves the nest for food and water, she will cover the eggs
with down and grass until she returns. The water that drips off her feathers
helps to keep the nest humid, which is necessary for proper growth of the
embryos. The gander will chase away anything that threatens his mate or his
nest by sending a loud warning honk, then stretching his neck out low to the
ground, shaking his head back and forth, and charging the invader.
After approximately a month of incubation, the goslings hatch. Using a
strong projectile on the tip of their bill called the egg tooth, the young
crack the shell and emerge. Within 24 hours, the goslings are led to water.
Canada geese are precocial, which means they hatch covered in down and have
the ability to walk, run, swim, and eat a day after they have emerged from
their shells.
The young imprint on their parents. Geese are not born with the knowledge of
how to live and survive like geese. By carefully watching their parents,
goslings learn where and how to find food, water, shelter as well as how to
communicate with other members of their species. They are also taught to
fear predators, fly, and swim.
Upon hatching, the downy covered goslings are very well camouflaged, as
their feathers are a yellowish olive green color. When threatened, they
flatten their bodies and look like a mound of grass. If they are threatened
from above while in the water, they can dive as deep as 35 feet to evade the
predator. When the goslings are about a month old, feathers start to replace
the fuzzy down. They begin to look more and more like the adult as the weeks
progress.
At six weeks of age, the colorings are similar to their parents, although
the gosling's white isn't as brilliant and the black is not quite as glossy.
An eight-week-old gosling weighs 24 times its birth weight. Imagine an eight
pound human baby at 2 months of age weighing 188 pounds! The reason for this
steady gain is so the young can be strong enough to migrate to the wintering
grounds in the autumn. Wings stretch and flap at this age to exercise the
muscles to get ready to fly. About the same time the goslings are beginning
to beat their wings and make short flights, the parent birds are starting to
grow back their flight feathers they shed a month earlier. Soon, the entire
family will begin its annual migration southward.
Migration is an event that is still not entirely understood by scientists.
It is known that most Canada geese travel the same routes or paths each year
and arrive at the same wintering and breeding grounds. These routes are so
well established that several populations of Canada geese result. For
example, throughout the Atlantic Flyway, of which Connecticut is a part, the
North Atlantic population can be found migrating, wintering, breeding, and
nesting in the same areas each year. This population of Canada geese may
progress from northeastern Canada in the summer months through New England,
and down to North Carolina for the winter.
These magnificent birds may migrate both by day and by night, stopping often
for rest, food, and water. Geese and swans make their migration in family
groups and are led by experienced adults who have made the trip before. It
is believed that they find their way by watching for familiar landmarks,
such as mountains, cities, rivers, and lakes. It is also likely that the
position of the sun, moon, and stars in the sky as well as the earth's
magnetic field helps them to find their way.
When flying together, Canada geese will often form a V-shaped pattern. The
lead goose has the most exerting job, as it must break the wind. As the
geese flap their wings, an uplift is created which makes it easier for the
geese flying at the end of the formation. Oftentimes you may hear the geese
flying overhead before you actually see them. Communication is a vital part
of the social bonds of Canada geese and they will honk their encouragement
to each other to keep their speed up, which can reach speeds of 60 mph.
If a member of the flock drops down due to illness or exhaustion, others may
fly down to the ground and stay with the bird until it is either ready to
rejoin the flock or unable to continue. Canada geese form strong social
bonds as they mate for life, nurture their young, and communicate often with
each other.
A Canada goose is seldom seen alone; it is most likely to be with a mate, in
a family group, or with a flock of other geese. Adults may be heard honking
for several reasons: alarm and distress, encouragement, or greeting a mate
or family member. They may hiss to chase off intruders and make softer calls
to utter contentment. Goslings peep rapidly when separated from parents and
form laughing-type sounds that symbolize comfort.
Connecticut's resident Canada geese (Branta canadensis maxima) are a
non-migratory, imported race that live in local parks get so accustomed to
people feeding them that they will walk right up to a person; however, it is
important to remember that Canada geese are wild animals. They do not like
to touched, chased, or surrounded. They will defend themselves and their
families if they feel threatened. If a goose is hissing, bobbing its head,
and/or shaking its neck back and forth, it is telling you that you are seen
as a threat and should back away.
Canada geese, as with all wild animals, can be best observed and enjoyed
from a distance. By sitting silently, listening to the geese communicating,
and unobtrusively viewing their behavior you may learn how these interesting
creatures bond and socialize with each other!
Sea Gulls
Gulls and other related sea birds exist in great numbers along coastal areas, large lakes and rivers. A subset of long winged swimming birds, there are 45 species of Gulls. Twenty species are resident (nesting) in North America and four are visitors (non-nesting). An intelligent bird, they will carry mussels and clams high in the air and drop them on hard surfaces to get to the soft meat inside. Gulls have the ability to drink saltwater and freshwater, thanks to a pair of salt removing glands above their nostrils. They are good swimmers who can walk or run agilely on land. Gulls are scavenging birds; they will eat everything from dead fish and garbage to field mice and insects. Gulls enjoy protection at the federal, state and local levels.
Damage
Gulls can be a nuisance in coastal areas, particularly at dump sites, piers and harbors. Flocks of gulls often create hazardous conditions to low flying aircraft. Large buildup of droppings will lead to structural damage from the uric acid. Boats, streetlights and buildings are just a few of the items damaged from excessive gull droppings. Furthermore, their droppings can also pose a health risk.
Control
Gridwire systems and large 4" mesh StealthNet will deny access to large open areas. Bird-Flite spikes, 5" Bird Coil, and Bird-Shock electrical track
are very effective on ledges depending on the level of bird pressure. The
Daddi Long Legs is a great product to dissuade gulls from landing on silos, street lights, A/C units & large flat rooftops. For feeding sites such as dumps, a wide variety of audio/visual products like the Avikite or Flying Osprey and noisemakers like Zon Guns, Bird Bombs and Screamers, or high tech multiple and random sound distress call units like the BirdGuard, Squawker or BirdWailer units should be combined with exclusionary products such as Gridwire systems or 4" StealthNet.
Nesting
Gulls build basic nests on the ground in safe open areas. The nest often consists of grass, seaweed and some sticks. They nest in colonies on sandy or gravely areas near the shore.
Breeding
These birds have one brood a year with an average of three eggs. Incubation takes 20 to 24 days with a six week fledgling period before the young leave the nest. The eggs are brown, green or blue with blotches of black, brown or gray.
Cycles
Some species are migratory. Gulls need open water and secluded breeding areas. Because of this, Northern Gulls will fly south away from frozen lakes and rivers in the winter, while southern gulls stay put year round. They have a distinct springtime breeding season. The young take two years to mature and display adult plumage.
Monk Parrots
Description
12", looks similar to mourning dove in flocking flight. Predominantly green with gray forehead and gray scaling on breast, dark blue primaries. Eyes are brown, bill beige and legs gray.
Range
Naturally occurs in southern South America: central Bolivia and southern Brazil to central Argentina, including Paraguay and Uruguay. Exotic in U.S. with populations in CT, CA, IL, FL, MD, TX and RI.
Food
Virtually omniverous including fruits, cereal, seeds, nuts, leaf buds, grasses, blossoms, insects and insect larvae; have also been observed eating meat according to Forshaw. Considered an agricultural pest in South America, this has yet to be documented in ornithological literature.
Nesting
Only species of parrot (Family Psittacidae) to build stick nests. Nests can contain many separate chambers that house pairs (or more). Apparently only one breeding season in temperate zone with fledglings appearing in June-July. Young fed by regurgitation.
Habits
Gregarious; noisy, raucous calls and many other vocalizations. Fly strongly but seldom for long distances. Climb using bill. "Waddling" walk caused by zygodactyl configuration of toes -- two in front and two in back.

The female House Sparrow looks somewhat similar to a number of species of sparrows but has unstreaked underparts, tawny streaks on the back, and a large yellowish bill. The female Dickcissel also has a large bill but it is gray, not yellow, and usually has some yellow in the face and a rusty patch in the wing.
Starling
The European Starling, Sturnus vulgaris, is a native of Eurasia and North
Africa. Sometimes known as the common Starling, the European Starling is
found in Europe, Australia, New Zealand, South Africa, North America, and
some of the Caribbean islands. Common names for the European Starling are:
Star (DE), Estornino (ES), Etourneau sansonnet or Sansonnet (FR), Storno
(IT) Estorninho (PT), and of course, Starling, in English speaking
countries.
Description
The European Starling belongs to the family Sturnidae, order Passeriformes.
Sturnidae, are perching birds that number more than 111 species, including
the Mynah. The European Starling can be described as a stocky, medium-sized
black bird with a short tail. The tip of the tail just barely extends beyond
the tips of the closed wings. In flight, the Starling has a distinctly
triangular shape. The European Starling is about the same size as a Robin.
The total length of the European Starling is about 8.5 inches (21.6 cm).
Summer plumage is a glossy black with iridescencent purple and green
feathers that are tipped in white. The legs are a reddish color. The bill is
tapered and conical, and is yellow-colored in the summer. Except for
possible escaped exotic Mynah birds (common, crested, and hill Mynahs), the
Starling is the only black-colored bird with a yellow bill found in the
United States.
Winter plumage is black with light colored tips on the feathers. Both summer
and winter plumage give the Starling a distinctly speckled appearance. The
bill is dark brown in winter. Young Starlings have brown-grey feathers and a
whitish throat. Juveniles are brown with a dark bill, and might be confused
with female and juvenile blackbirds, except for their characteristically
short tails. The tip of the tail just barely extends beyond the tips of the
closed wings. In flight, the Starling has a distinctly triangular shape. A
spot at the base of the bill provides the only color difference between the
sexes - bluish in males, reddish in females. Females usually have a slightly
more spotted appeareance.
The Starling produces a number of characteristic rasping, squawking, or
squeaking calls (23k .au file), most of which are harsh and unpleasant to
hear. As a relative of the Mynah, the Starling is an excellent mimic, and
frequently imitates the calls of many other species of birds. The call of
the Starling is frequently mistaken for that of a Robin, Bobwhite Quail or a
Meadow Lark.
Range within the USA
The European Starling is believed to have been introduced to the United
States circa 1890, when approximately 100 birds were released in New York
City. After living in that part of the country for about 30 years, they
rapidly extended their range. Starlings are now are found from
coast-to-coast in most areas of the country, extending into Alaska. In 1994,
there was an estimated population of 140 million birds. The greatest
concentration of Starlings, in the United States, is in the Mid-West and
along the Atlantic coast. In the fall and winter months, Starlings form
huge, noisy, gregarious flocks in the Southern states. Starlings may form
large single species flocks, or be part of immense flocks containing
Starlings, several species of Blackbirds, common Grackles, and Cowbirds.
Feeding habits
The European Starling is extremely voracious, and is truly omnivorous (eats
everything). Starlings are highly adaptive, and in time of food scarcity
they will feed on almost anything, including garbage. More than half of
their diet is made up of insects, especially moths and butterflies (and
their caterpillars), beetles (especially their larvae, grubs in lawns),
crickets, and grasshoppers. Starlings feed their young entirely on insects.
Starlings are also fond of earthworms.
Starlings eat a wide range of seeds, grains, and fruits - both natural and
cultivated. Starlings are a serious pest in grain-producing regions, due to
their fondness for corn, wheat, milo, and other grains. Starlings can be
very destructive to such agricultural crops as strawberries, blueberries,
grapes, tomatoes, peaches, figs, apples, and cherries. They consume large
quantities of livestock feed, and they can have a significant impact on the
cost of dairy, egg and poultry production. Starlings will also pull up newly
planted seeds, causing reduced yields. Starlings feed on poke berries,
elderberries, and wild cherries producing droppings that can cause unsightly
stains.
Breeding habits
Starlings breed from March through July. In spring and summer, breeding
pairs disperse rather than stay with the concentrated flocks. Nests are
bulky collections of sticks, dried grasses, other plant fibers, paper,
feathers, and similar debris. Nests are built in both natural and artificial
cavities. Breeding pairs will take over woodpecker holes and bird houses. It
is common for Starlings to nest in cavities displacing native song birds.
Starlings commonly nest in man-made structures: between rafters in barns and
open warehouses, in or behind signs, and in soffits and attics of houses.
They commonly enter attics through torn or missing soffit or attic vents,
openings where wires or plumbing enters the building, and even under loose
siding. A clutch of eggs normally consists of 4 to 6 light blue-green eggs.
The incubation period is 11 to 13 days. A pair of Starlings will sometimes
produce a second clutch of eggs in the same year.
Roosting habits
Fledglings leave the nest at about 21 days of age, after which they form
small flocks. As the summer progresses, the flocks increase in size to
hundreds or thousands of birds. In the evening, these large flocks may come
together from miles around to establish large communal roosts to spend the
night. Such roosts may number from a few thousand to several million birds.
Starlings prefer to roost in woods containing conifers, but may also roost
in reed beds, bamboo clumps or other woods and open spaces in cities. In
winter, the communal roosts usually consist of a larger number of birds than
the summer roosts. Since Starlings are somewhat migratory in their habits,
Starlings may move from the northern breeding areas to more southerly
regions in the fall months.
