Bird Control – The Ferral Pigeon
The wild Pigeon (Columba Livia)
In recent years as people have become more and more urbanized, birds have taken refuge in our buildings and homes, they can and often are a pest to humans. Under normal circumstances birds are protected but under the Wildlife and countryside Act 1981 (amended 1995) states that thirteen species of birds are recognized as public or agricultural pests of economic importance, which may be killed in certain circumstances by owners or occupiers of premises or their empowered agents, however in this article I shall discarded some more light on the wild pigeon.
Reproductive Biology of Pigeon
They lay two eggs and on average have 2-3 broods per year, the incubation period is anywhere between 17-19 days and they can use between 35-37 days in the nest, depending on food availability and how popular the conditions are they can produce more offspring.
Nesting and feeding habitats
wild pigeons prefer to make their nests on ledges, as long as it is flat surface protected from the elements, they make their nests out of twigs and use there droppings as cement to keep up the nest together, they will often only build one nest and return to it. wild pigeons prefer a diet of seeds, green satisfy and domestic scraps from humans and tend to satisfy near cities or roosting sites, wherever food is abundant.
Controlling the birds
General proofing: This consists of sealing holes in the building to prevent entry places for birds, proofing can be achieved by using expanding foam, chicken-wire, eaves-filler.
Avistrand: A system of wires and springs attached to the ledges of buildings to provide an insecure landing identify for birds which prevents them from settling, this system is particular suited for pigeons and gulls.
Bird repellent: a non-setting gel applied to ledges, which presents an insecure landing site, preventing birds from settling, this system will work for a period of a year.
Netting: Nylon netting used to net off access to roosting areas such as light wells, pipe runs, ventilation shafts, net sizes for wild pigeons should be about 50mm
Trapping: Specially designed cages can catch birds and they can moved away.
Shooting: The use of specialized air rifles by a fully trained pest control officer trained in the methods of humane shooting of birds.
Why they are a nuisance?
The close association of birds and people and animals is likely to spread diseases such as Salmonella, Ornithosis and Fowl pest.
When birds settle on buildings they leave their droppings down the side of buildings which very unsightly.
In factories their droppings and feathers may contaminate food production and may be a health risk.
