There was an extraordinary increase in the numbers of European gulls during the twentieth century which has been linked to higher availability of food derived from human activities. At Berlenga island (Portugal), the population of yellow-legged gulls Larus michahellis increased from 2600 individuals to a peak of 44,698 gulls (1974–1994), after which control measures have been put in place. Despite the management effort, little is known about the feeding ecology of this population. To… 

A Gull that Scarcely Ventures on the Ocean: Yellow-Legged Gulls Larus Michahellis Atlantis on the Oceanic Island of Madeira

Summary.— The yellow-legged Gull Larus michahellis atlantis (YLG) is a generalist and opportunistic species that explores different habitats and resources and easily adapts to humanised

Intra-population variation in the diet of an avian top predator: generalist and specialist foraging in Great Black-backed Gulls Larus marinus

Variation in diet among pairs emphasizes that not all individuals contribute equally in terms of predation, and has important ecological implications, particularly where apex predators may exert a strong top-down influence.

How fishing intensity affects the spatial and trophic ecology of two gull species breeding in sympatry

Fisheries produce large quantities of discards, an important resource for scavenging seabirds. However, a policy reform banning discards, which is soon to be implemented within the EU, will impose

Foraging strategies of a generalist seabird species, the yellow-legged gull, from GPS tracking and stable isotope analyses

An overall preference for the marine and mix strategies in yellow-legged gulls is highlighted, influenced by oceanographic conditions and availability of marine food sources nearby the colonies.

Anthropogenic food resources, sardine decline and environmental conditions have triggered a dietary shift of an opportunistic seabird over the last 30 years on the northwest coast of Spain

Human activities and environmental conditions are the main drivers of ecosystem change. One major alteration near the western Iberian coast has been the collapse of the Atlanto-Iberian sardine

Breeding Yellow‐legged Gulls increase consumption of terrestrial prey after landfill closure

In conclusion, landfill closure or the use of deterrence systems had a direct impact on the trophic ecology of Yellow‐legged Gulls; loss of refuse was mainly compensated for by prey of terrestrial origin when breeding, but not in winter.

Recently-adopted foraging strategies constrain early chick development in a coastal breeding gull

Results of this study suggest that terrestrial diets may lower reproductive success due to limitations in food quantity, rather than quality, for breeding Lesser Black-backed Gulls during the chick-rearing period.

Ingestion of anthropogenic materials by yellow-legged gulls (Larus michahellis) in natural, urban, and landfill sites along Portugal in relation to diet composition

The presence of certain debris categories in gull pellets was positively related to the presence of some prey items, suggesting that gulls may accidentally ingest debris while foraging at multiple habitats.

Diet of Yellow-legged Gull (Larus michahellis) chicks along the Spanish Western Mediterranean coast: the relevance of refuse dumps

The diet of Yellow-legged Gull chicks is described, with particular emphasis on establishing the dependence of each population on refuse dumps, in order to forecast changes in gull population dynamics in response to the management decisions being implemented.

Foraging distances of a resident yellow-legged gull (Larus michahellis) population in relation to refuse management on a local scale

Testing whether the closure of one large dump and the use of falconry to deter gull access to two others, within the southeastern Bay of Biscay area, affected the foraging distance of local yellow-legged gulls supported the hypothesis that refuse management within the region influenced the movement patterns of local gulls.

The diet of Atlantic Yellow-legged Gulls (Larus michahellis atlantis) at an oceanic seabird colony: estimating predatory impact upon breeding petrels

The diet and breeding ecology of Yellow-legged Gulls were studied on Selvagem Grande, North Atlantic in the nesting season of 2007 and the importance of the estimated predation levels is discussed and some management actions are suggested.

Annual and seasonal consistency in the feeding ecology of an opportunistic species, the yellow-legged gull Larus michahellis

The hypothesis that individual feeding preferences throughout most of the annual cycle are an intrinsic characteristic of this population, and potentially of related opportunistic and generalist species, is supported.

High importance of fish prey in the diet of Yellow-legged Gull Larus michahellis chicks from the southeast Bay of Biscay

These findings concur with those at colonies in northwest Iberia, and while local exceptions might occur, Yellow-legged Gull chick diet in northern IberIA is predominantly marine fish.

Comparative analysis of the Yellow-legged Gull’s (Larus michahellis (Naumann, 1840)) trophic ecology in two colonies of the Central Coast of Algeria

It is surprising that the proportion of inorganic remains in pellets of Yellow-legged Gull adults on the Aguelli Island (33.24%) is the largest, followed by the food category represented by terrestrial prey, and vegetation remains ranking last (20.45%).

Seasonal and Age-Dependent Dietary Partitioning between the Great Black-Backed and Herring Gulls

Evidence of dietary partitioning between species and age classes is revealed, and the strengths and biases associated with techniques for sampling gulls' diet are highlighted.

Using a Three-Isotope Bayesian Mixing Model to Assess The Contribution of Refuse Dumps in The Diet of Yellow-Legged Gull Larus michahellis

This study demonstrated the importance of isotopic variability among years for inferring diet diversity and food availability for the colony, thereby allowing demographic forecasts when trophic resources vary in abundance or the foraging habitat is disturbed.

Influence of food availability on interactions between Larus cachinnans and L. audouinii

A positive association between depleted food and the response by Audouin's gulls to aerial intrusions is indicated, and chick predation is significantly higher only during the period when yellow-legged gull has fledglings.
