The functional connectivity network of wintering gulls links seven habitat types, acting ricefields as the central node

The lesser black-backed gull is now the second most abundant wintering waterbird in Andalusian wetlands. Many birds are fitted with GPS loggers on their breeding grounds in northern Europe, and using 42 tagged individuals we studied the connectivity network between different sites and habitats in Andalusia.
