Migratory birds are changing their behaviour in response to climate change: they arrive in the places for reproduction in advance.
It is a study conducted by the University of Edinburgh, where researchers have analysed hundreds of species of the 5 continents. The result is that, on average, these birds reach their summer habitats a day earlier than normal for each higher grade of global warming.
Such a small change can have important repercussions on the life and reproductive capacity of hundreds of species of birds. As Edinburgh researchers explain, if migratory birds get to their destination at the wrong time, even just a few days earlier, they may be disadvantaged in the research of food and nesting site. Consequently, the time of hatching and the chances of survival of chicks may be also influenced.
