On the occasion of the European Bird Migration Days this first weekend of October, guided walks are organized in Releghem in Flemish Brabant to observe and learn more about migratory birds and above all to raise awareness of the need to protect the environment.
Because more and more migrants are affected by climate change. Evidenced by the disappearance of hedges whose species are full of insects. “The destruction of hedgerows is a big problem because these insectivorous birds that migrate at night land in hedgerows must lengthen their stages so exhaust themselves a little more or feed a little less“, indicates Alain Paquet, ornithologist and member of the association nature protection Natagora.
The drying up of wetlands, increasing desertification and rising temperatures can also modify the route.
The problem is that the changes are being made very quickly.
“The problem is that the changes are being made very quickly. Migrations took place roughly at the end of the last ice age. They crystallized over three to four thousand years. There, it is over a few decades that the species must adapt“, concludes Alain Paquet.
