These birds are capable of breeding year-round, but peak season runs from March to late August. Nests can be found on virtually any ledge or horizontal surface which provides a modicum of shelter. The nest is usually made of grass and twigs, but many pest technicians will recount stories of nests made from plastic, wire and other scrap materials. The nest becomes more substantial with each brood raised.
A normal clutch consists of two off-white eggs laid on consecutive days. These are incubated for 18-19 days, and it can occur that the female incubates the eggs at night and the male take over during the day. Fledging takes place after 30-32 days and a further clutch of eggs can be laid when the first young are only three weeks old. It is possible for feral pigeons to produce 9 broods a year, but 4-5 is more normal.
The pigeon is often called ‘the flying rat’ and carries the most of the same diseases and many more besides. Their presence in around food producing factories, restaurants and cafes, food shops, farms and docks, hospitals and other such buildings cannot be tolerated.
They can also cause serious damage and nuisance; the noise they create from cooing and scratching (especially in the early morning and evening), damage to cars, domestic premises, monuments and commercial properties due to droppings, and of course the smell.
