Researchers watched birds that landed on feeders that were on the edge of woodlands and in hedgerows on the Penryn Campus in Cornwall for four hours a day between November and December 2016.
Their findings show that the heavier and larger birds have better access to food. Species like greenfinches and house sparrows spent much longer feeding than smaller birds. Tiny birds such as coal tits and blue tits had to rush at the feeder and as such were left with lower quality food.
Heavier birds dominated the sunflower hearts – a food that is quick and easy to eat. This left the smaller and lighter birds with the whole sunflower which is a food that takes longer to open and eat due to the husk.
However, there are things that you can do to help. Consider a product like our Ground Feeding Haven which has adjustable mesh to allow the smaller birds access to feed.
Our gardens have become a haven for countless birds which have undergone habitat loss and urbanisation which indicates that they continuously need our help.
