UK garden birds are evolving bigger beaks, a new study has claimed. It has been found that UK garden birds are evolving bigger beaks due to people feeding the birds in their gardens. Feeding the birds in gardens has helped UK garden birds evolve. This is because their beaks have grown larger to help them get food from garden bird feeders. Which means garden bird feeders put out by people in the UK, have helped this bird evolution, for our tiny feathered friends.
This evolution has occurred in a short period of time, over the the last forty years.
The wildlife study compared birds in the United Kingdom, with birds in mainland Europe. The wildlife study found that birds in the UK were impacted with people feeding them in their gardens. They were impacted by evolving to survive in gardens, by developing longer beaks which are suitable for bird feeders.
