Bird Proofing Services

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.

Bird Proofing Services 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.

    Similar species:

    The adult male House Sparrow is quite distinctive but might be confused with the very local Eurasian Tree Sparrow (St. Louis, Missouri). The Eurasian Tree Sparrow has a black spot on the ear coverts and an entirely brown crown. 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.
