Birds play crucial roles in pollination and pest control, and a lack of insects disrupts these ecosystem functions. Overpopulation of certain insects, without natural predators from birds, can also cause outbreaks that damage plant health and agriculture.
The World Migratory Bird Day campaign in 2024 will stress the need for proactive conservation measures. This includes reducing the use of pesticides and fertilisers, and where possible, switching to organic farming. Other measures include maintaining and connecting areas of natural vegetation which provide food and shelter for birds and other species, in agricultural landscapes.
In 2024, World Migratory Bird Day will be celebrated on two days, 11 May and 12 October, aligning with the cyclic nature of bird migration in different hemispheres.
