Gulls are intelligent small to large seabirds which inhabit coastal areas and inland urban areas. There are many types of gulls but most are white, grey and black when mature. When gulls are nesting they will return to the same site each year unless access is restricted, the site is rendered unusable or there is a gull deterrent in place.
Gulls are exceptional flyers and have strong legs which provide good mobility on land or a rooftop. Their diet is varied and they are superb scavengers often seen around urban areas where refuse is unsecured or litter is regularly discarded.
Nesting commences in February/March and a typical gull clutch will consist of 3 eggs with both sexes incubating although some do so singly. Once gulls have built their nests and had young they can become very aggressive if they feel their nest is threatened, this is often a problem in urban areas.
Gulls are habitual so if you have gulls nesting this year they will back to nest next year. You can also expect twice the number as this years young will return also, its imperative you have have a gull management plan in place before they start nesting
If you have or have had a gull problem it is recommended you should consult an experienced bird expert rather than a general pest controller.
Gulls will only recycle new eggs once a year as they have to incubate the eggs for a period of 31 days. If the eggs are removed before being incubated the gulls will continue to recycle. If the eggs are incubated for too long there is a risk they will hatch, once hatched the baby gulls are then protected. Generally the gulls will be present on the roof for a period of 6 months each year and return in greater numbers as the young become mature after 3 years and return to their natural breeding site.
