Understanding Gull Breeding Season & How Vergo Can Help

Gulls are a familiar sight along the UK’s coastlines, inland waterways, and increasingly in urban areas. While these birds play an important role in the ecosystem by controlling insect populations and cleaning up waste, their breeding season can bring significant challenges for businesses and homeowners. Nesting gulls can not only cause noise disturbances, but significant property damage, and even aggressive behaviour when defending their young.

At Vergo Pest Management, we understand the challenges posed by gull activity. Our expert team specialises in tailored proofing solutions designed to effectively mitigate issues related to gull breeding – all while ensuring full compliance with wildlife protection laws.

When is Gull Breeding Season in the UK?

Gulls typically breed from spring to early summer, with slight variations depending on the species and location. Their breeding cycle follows these key stages:

  • March – April: Gulls return to their nesting sites, often in colonies, and begin establishing territories.
  • May – June: Nest building begins, and females lay two to three olive-coloured eggs per clutch and will only have 1 clutch per year if successful but may attempt laying up-to 3 times if unsuccessful.
  • June – July: Chick’s hatch and remain highly dependent on their parents for food and protection.
  • July – August: Juvenile gulls fledge but may still receive food from their parents as they learn to forage for themselves.

Gulls are known for their strong site fidelity, meaning they return to the same nesting locations each year. This makes early intervention crucial for long-term prevention.

Where Do Gulls Nest?

Gulls are highly adaptable and will nest in a variety of locations, including:

  • Coastal cliffs and islands – Traditional nesting grounds, particularly for herring gulls and kittiwakes.
  • Inland lakes and rivers – Some species, like black-headed gulls, prefer nesting in wetlands.
  • Urban areas – Rooftops, car parks, and even chimneys provide ideal nesting spots, particularly for herring gulls and lesser black-backed gulls.

The rise of urban nesting gulls in towns and cities across the UK has led to increased conflict, as buildings mimic their natural cliffside nesting habitats. Left unmanaged, gull colonies can grow rapidly, leading to recurring problems year after year.

Gulls usually have 3 distinct sites during the breeding season:

  • Nesting site – This is where the gulls sleep, lay eggs, go through the gestation period and raise their young.
  • Feeding site – This is as indicated where they feed and where they get enough food to take back to the nest for their partner and young, this also includes day roosts overlooking feeding sites such as lampposts in a fast food car park or on a building overlooking a bakery shop or fish and chip shop on the seafront or in a town centre.
  • Loafing site – This is usually somewhere between the other 2 sites often closer to the nesting site, this is where the gulls empty their bowels after feeding before they return to the nesting site.

Each of the three sites presents unique challenges in managing the gull population. However, at Vergo, our expertise enables us to develop effective, site-specific management plans that licensing bodies rely on when assessing mitigation measures and approving control applications.

Common Problems During Gull Breeding Season

Even though all gulls are a protected under UK wildlife laws, their nesting habits can cause several challenges, including:

  • Aggressive Behaviour – During nesting season, adult gulls become highly protective of their eggs and chicks, often swooping at people and pets who venture too close. Reports of gull attacks are common in areas where they nest on buildings.
  • Noise Disturbances – Gulls are particularly noisy during breeding season, with increased calls and warning cries, especially in the early morning and late at night. This can be disruptive for businesses, hotels, and residential areas.
  • Mess & Property Damage – Gulls produce large amounts of droppings, which can create unsanitary conditions and damage vehicles, roofs, and pavements. Their nests, often made from debris, can block gutters and drainage systems, increasing the risk of water damage.
  • Food Scavenging & Waste Disruption – Gulls are notorious scavengers and will aggressively raid bins, outdoor dining areas, and food storage sites. This poses hygiene risks, particularly in hospitality, food production, and public spaces.
