What You'll Learn
Seagulls are scavengers and hunters
Seagulls are highly adaptable and opportunistic scavengers and hunters. They are omnivorous birds of prey that feed on a diverse range of food items, including both natural and human-made products. Their diet includes small fish, marine invertebrates, crustaceans, molluscs, insects, earthworms, rodents, birds, eggs, chicks, berries, seeds, fruits, vegetables, grains, and human food waste. Seagulls have a long, hooked bill that makes them adept at hunting and consuming fish. They also scavenge for food in landfills, dumps, and other areas where human food waste is present, such as beaches, parks, and waterfronts.
The diet of seagulls can vary depending on their species, location, and resource availability. For example, Ring-billed Gulls frequently scavenge in urban areas and agricultural settings, while Laughing Gulls focus more on natural foods, following fishing boats for discarded catch. During the breeding season, adult seagulls prioritise protein-rich foods like fish, crustaceans, and marine invertebrates to ensure the healthy development of their chicks.
In addition to their scavenging behaviour, seagulls are also effective hunters. They often hunt in groups, working together to obtain food from other animals. Seagulls are known to harass other birds to steal their food and will even prey on small birds and mammals, including rabbits and puffins. Their ability to hunt and scavenge a variety of food sources contributes to their success as a species and their ability to thrive in diverse habitats, from remote coastlines to urban centres.
While seagulls are adaptable feeders, their diet choices can sometimes be detrimental to their health. Consuming human food waste, such as bread, chips, and processed foods, can lead to nutritional deficiencies and health issues. Additionally, scavenging in landfills and polluted areas increases the risk of ingesting plastics and other harmful materials. Despite these risks, seagulls' dietary adaptability and opportunistic behaviour have allowed them to become successful and widespread birds.

Human food and waste
Seagulls are highly opportunistic feeders with a diverse diet that includes human food and waste. They are omnivorous birds that are highly effective scavengers and hunters. They have a reputation for being "trash pickers" and will eat anything from landfills, beaches, parks, fishing vessels, and restaurants. Seagulls have adapted well to living with humans and have benefited from this proximity, which has led to an increase in their population in urban areas.
Urban gulls frequently scavenge for food in landfills, dumps, and garbage bins, where they find human-made foods like bread, chips, and other processed foods. Studies have shown that over 70% of the winter diet of Ring-billed Gulls may come from landfills. Human food is not always beneficial to gulls, and regular consumption of these items can lead to nutritional deficiencies and health issues. Chicks raised primarily on human food waste show higher rates of developmental problems.
Seagulls are often seen in flocks along coastal areas, where they scavenge for food dropped or thrown by beachgoers. They also follow fishing boats in search of discarded bycatch or leftovers. Their ability to adapt to both natural and human food sources has allowed them to thrive in environments ranging from remote coastlines to urban centres.
In addition to human food waste, seagulls also consume a variety of natural foods. They eat small fish, marine invertebrates, crustaceans, molluscs, insects, worms, rodents, birds, and eggs. They are not picky eaters and will even scavenge for dead animals, agricultural pests, and other small prey. Seagulls have keen senses of sight and smell, which help them locate food and secure it before other competitors.
While seagulls are known for their opportunistic feeding behaviour, they do exhibit some selective tendencies. During the breeding season, adult gulls shift their diet to include more protein-rich foods like fish, crustaceans, and marine invertebrates, which are essential for the growth and development of their chicks. They also avoid junk food during this period, focusing on more nutritious options to feed their young.

Natural food sources
Seagulls are omnivorous birds of prey with a highly diverse diet. Their natural food sources include fish, marine invertebrates, crustaceans, molluscs, insects, earthworms, rodents, reptiles, amphibians, and other beach-dwelling creatures. They also eat the eggs and chicks of other birds, berries, seeds, fruits, grains, and vegetables.
During the breeding season, adult seagulls shift their diet to emphasise protein-rich foods like fish, crustaceans, and marine invertebrates, which are essential for their growing chicks. Seagulls are known to forage up to several miles from nesting colonies to find food for their young.
The specific diet of seagulls can vary based on species and location. For example, Laughing Gulls tend to focus on natural foods, frequently following fishing boats to catch discarded bycatch. In contrast, Ring-billed Gulls are more likely to forage in agricultural and urban settings, with over 70% of their winter diet coming from landfills.
Inland seagulls are more likely to eat insects, worms, fruits, and seeds, while coastal seagulls may consume more fish and marine invertebrates. Seagulls are highly adaptable and opportunistic feeders, so they will take advantage of whatever food sources are available in their environment.
While seagulls primarily consume natural food sources, they have also been known to scavenge for human-made foods, such as bread, chips, and other food waste. This behaviour is more common in urban seagulls, who have easy access to garbage, restaurants, and leftovers from boats. However, consuming human-made foods can lead to nutritional deficiencies and health issues for seagulls, and it increases their risk of ingesting plastics and other pollutants.

Seagulls' diets vary by species and location
Seagulls are omnivorous birds of prey with a highly diverse diet that varies depending on their species and location. They are known for their opportunistic feeding behaviour, consuming a wide range of food items, including natural and human-made sources.
In coastal areas, seagulls feed on small fish, crustaceans, marine invertebrates, and other beach-dwelling creatures. They are skilled at hunting and eating fish, using their long, hooked bills to their advantage. Seagulls also scavenge for food in fishing harbours, targeting cleaning stations or bycatch.
Inland seagulls may have a different diet, focusing on insects, worms, fruits, seeds, and agricultural crops. They are often seen in recently ploughed fields, where they feed on insects and act as pest controllers.
Urban seagulls have adapted to human environments and frequently scavenge in landfills, parks, and waterfronts for human food waste, such as bread, chips, and other leftovers. This dietary shift has led to an increase in the gull population in cities and has raised concerns about the potential health risks associated with ingesting plastics and other pollutants.
During the breeding season, adult seagulls prioritise protein-rich foods like fish, crustaceans, and marine invertebrates to ensure the healthy development of their chicks. They regurgitate partially digested food for their young and gradually introduce whole food items as the chicks grow, teaching them essential foraging skills.
Different species of seagulls also exhibit varied diets. For example, Ring-billed Gulls are frequent foragers in agricultural and urban areas, while Laughing Gulls tend to focus more on natural foods, following fishing boats for discarded bycatch. Great Black-backed Gulls, the largest species, hunt smaller birds and mammals, including rabbits.

Chicks' diets and feeding methods
Seagulls are omnivorous seabirds with a highly diverse diet. They are known for their opportunistic feeding behaviour, consuming a wide range of natural and human food sources. The diet of seagulls includes fish, crustaceans, molluscs, marine invertebrates, insects, rodents, birds, berries, seeds, nuts, and even human food waste.
Seagull parenting involves remarkable feeding adaptations to ensure chick survival. During the breeding season, adult seagulls shift their diet to focus on protein-rich foods, which are essential for the growth of their chicks. These include fish, crustaceans, and marine invertebrates. The parents forage for food and return to their nesting colonies with partially digested food, which they regurgitate for their young. This feeding method allows adults to efficiently transport multiple food items in their crop, a specialised pouch in their digestive tract.
The chicks communicate their hunger through begging calls and by pecking at a red spot on the parent's bill, stimulating the regurgitation response. As the chicks develop, parents gradually introduce whole food items, teaching them crucial foraging skills before they become independent. Both parents are involved in feeding the chicks, with the male typically doing most of the feeding while the female focuses on brooding and guarding the chicks.
While seagulls in the wild primarily feed their chicks natural prey, studies of urban gull populations have shown that chicks raised mainly on human food waste may experience higher rates of developmental issues. Therefore, it is important to understand the negative impact of human food on seagull health and avoid encouraging seagulls to depend on human food sources.
