Due to severe drought, migratory birds that traditionally reside in Southern Europe are now finding their way to Flanders. Experts believe the migratory phenomenon could be explained by climate change.
Around 20 griffon vultures have been spotted in Flanders, a species which usually resides in the warm temperatures of Greece.
Other unusual birds recently spotted in Flanders were, among others: the European Roller which usually resides in southern Europe and North Africa; the bee-eater, usually found in climates such as Australia, Asia, Africa and Southern Europe; and the black-winged stilt that enjoys wetlands in warmer regions in every continent.
While the arrival – and even the successful breeding of some – of these colourful migratory birds have treated Flemish birdwatchers to unusual sightings, their arrival can be put down to changing climates and a much drier summer in Southern Europe, as well as a warmer Belgium.

Another cause for concern is that Belgium experienced a very cold spring, meaning that this summer will have fewer insects. This could leave these new arrivals with a reduced food supply. While it is still uncertain what the effects will be, it is almost sure that the future breeding of these birds may be affected, Het Laatste Nieuws reports.
