  • Seagulls eat toxic food
    Some food eaten by humans is fine for birds, too. For example sunflower seeds, corn and fruits would be safe for many birds. Also insects (which are technically also eaten by humans at times and in some regions). But most human food will have hazardous effects on the health of birds.
    Supplementary feeding can affect populations of birds. It reduces energy spent on foraging and reduces the risk of starvation, but it also increases the risk of disease transmission and predation. Supplementary feeding may reduce species richness if some species are better able to exploit supplementary food resources than others. Feeding may also artificially inflate the carrying capacity of the ecosystem, leading to bird nuisance in the form of droppings and noise. The aim of this study was to characterise and quantify the risk factors and consequences of feeding free‐living birds in public areas in the western part of the city of Amsterdam. In seven study areas, the following data were collected: bird population size and species composition, feeding events, and the type and amount of supplementary food offered. Estimations were made of the nutritional energy provided and the number of birds that could be supported by the food offered. Members of the public who fed the birds were invited to complete a questionnaire on various aspects of feeding. Results showed that supplementary feeding attracts juvenile gulls and feral pigeons, which could in the long‐term affect biodiversity. Bread was the main category of supplementary food being offered (estimated to be 67% of the total amount of food). The majority of respondents fed birds so as not to waste bread and meal leftovers. In six of the seven areas studied, an overabundance of nutritional energy was calculated. We conclude that the current type and extent of supplementary feeding in the city of Amsterdam is nutritionally unbalanced and affects species diversity at a local level. The overabundance is undesirable for reasons of both animal health, because it can lead to malnutrition, and public health, because surplus food attracts rats and may also have a negative effect on water quality.

    Great!!! Superb capturing of seagulls on mumbai coasts... beautiful to watch...
    Though its absolutely wrong to feed wild with processed food stuff.

    Very good information, video is too good, 👌👌👌👍 but it's not enough as people feeding them are not going to stop it untill one should hammer this facts into their mind, they should get informed while feeding this to bird's, I would love to join you if you are planning to make any descent awareness campaign on that feeding spot's.

    So sad, the same situation with feeding ducks with bread.
    Thank you for this video
