English or house sparrow (Passer domesticus) and the common starling are considerable agricultural pests, together causing an estimated US$1billion per year in crop damages. The large size of flocks can also cause problems. Common starlings may be sucked into aircraft jet engines, one of the worst instances of this being an incident in Boston in 1960, when sixty-two people died after a turboprop airliner flew into a flock and plummeted into the sea at Winthrop Harbor. The large roosts of the common starling pose many safety hazards for aircraft, mainly including the clogging of engines that concurrently shutdown the plane into descent. From the years 1990–2001, 852 incidents of aircraft hazard due to starlings and blackbirds were reported with 39 strikes causing major damage that cost a total of $1,607,317. Starlings' droppings can contain the fungus Histoplasma capsulatum, the cause of histoplasmosis in humans. At roosting sites this fungus can thrive in accumulated droppings. There are a number of other infectious diseases that can potentially be transmitted by common starlings to humans, although the potential for the birds to spread infections may have been exaggerated. The spread of disease to livestock is also a concern, possibly more important than starling's effects on food consumption or transmission of disease to humans. The spreading of Histoplasmosis reported in a Nebraska manufacturing facility saw a loss of 10,000 pigs from the spread of the disease which was valued at $1million loss in 2014. Control Due to the impact of starlings on crop production, there have been attempts to control the numbers of both native and introduced populations of common starlings. Within the natural breeding range, this may be affected by legislation. For example, in Spain, the species is hunted commercially as a food item, and has a closed season, whereas in France, it is classed as a pest, and the season in which it may be killed covers the greater part of the year. In Great Britain, starlings are protected under the Wildlife and Countryside Act 1981, which makes it "illegal to intentionally kill, injure or take a starling, or to take, damage or destroy an active nest or its contents". The Wildlife Order in Northern Ireland allows, with a general licence, "an authorised person to control starlings to prevent serious damage to agriculture or preserve public health and safety". The species is migratory, so birds involved in control measures may have come
