How do starlings affect humans?

How do starlings affect humans?

European Starlings can carry diseases that are transmissible to livestock and to people, including TGE (transmissible gastroenteritis – a disease of swine), blastomycosis, and samonella. All of these examples indicate that the spread of disease by starlings to humans and livestock is a potential threat.

How are starlings harmful?

None has been more destructive to native wildlife as the European Starling. They push out native cavity nesters like bluebirds, owls, and woodpeckers. Large flocks can damage crops, and their waste can spread invasive seeds and transmit disease.

Do starlings carry more disease than other birds?

Public health and starlings Dropping accumulation under roosts can encourage histoplasmosis fungus to grow in the soil. When disturbed, spores can become airborne, and people can breathe them in. Most people have no apparent ill effects. A few develop respiratory disease and a very few develop disease of other organs.

What problems is the European starling causing?

The most common problem caused by starlings are damage to crops and berries. When these birds are not eating pests, they in turn become pests and destroy farmers’ crops. Another negative impact is driving out competitors. Because starlings are so aggressive and gregarious, they force out many native species.

Do all starlings carry disease?

Starlings carry a host of diseases, many transferable to livestock, but several that can infect humans. Five bacterial diseases, two fungal diseases, four protozoan diseases, and six viral diseases may potentially be transmitted to humans and other animals by starlings (see this article from Utah State University).

Why are starlings so aggressive?

Starlings are so aggressive that they will out-compete native cavity-nesting species—such as bluebirds and Red-headed Woodpeckers—so your birdhouses are likely to home them instead of any birds you might want to attract. Starlings are considered one of the most destructive birds when it comes to native songbirds.

Will starlings damage my roof?

Human contact with starling droppings also carries a significant disease risk. Repeated and significantly large occurrences of bird fouling should be considered a sign of a potential pest bird infestation.

Why is the common starling invasive?

European Starlings are one of the world’s most successful invasive species. Known to compete with native bird species for nest sites, they may also compete with ground-foraging insectivores and other grassland species. Starlings avoid ungrazed pastures, presumably due to grass height, litter, or both.

How do starlings spread?

During the fall and winter starlings often frequent roosts with blackbirds, cowbirds (Molothrus ater), and grackles (Quiscalus quiscula), and it has, therefore, been thought that they travel together and that this accounts for the southward spread of the starling.

What kind of diseases does a European starling have?

The European Starling transmits five bacterial diseases including Salmonellosis, fungal diseases, blastonycosis, and histoplasmosis. They also carry the protozoan disease toxoplasmosis and chlamydiosis. Starlings spread fowl pox to poultry, swing gastroenteritis tapeworms and other livestock diseases.

What kind of disease can you get from Starling poop?

Histoplasmosis is a fungus that grows in soil affected by starling poop. Inhaling airborne spores causes infection, which gets worse with long exposure. This illness targets the lungs and is often serious for those with immune disorders. Homeowners can modify nesting sites to keep starling droppings from accumulating.

Why are Starling droppings bad for the environment?

These pests often nest in large flocks near homes and buildings. As a result, vast amounts of starling droppings collect below their roosts. When this waste pollutes the ground under the nests, mold and microbes develop quickly. Histoplasmosis is a fungus that grows in soil affected by starling poop.

Why are European starlings invasive to the United States?

European starlings (Sturnus vulgaris, Figure 1) are an invasive species in the United States. The first recorded release of the birds was in 1890 in New York City’s Central Park. Because starlings easily adapt to a variety of habitats, nest sites and food sources, the birds spread quickly across the country.
