When I was a child, I often saw my Grandma throwing bread that was no longer fresh to birds. Not surprisingly, this attracted few birds. Later on, we discovered bird food at the local store. Feeding garden birds in the UK has come a long way since then. Today, the birds can enjoy many kinds of food: from plant seeds to sunflower hearts and from cakes to meat balls. All this comes at a huge cost. Sometimes, I wonder ifwe might be feeding our garden birds better than our kids. But maybe it's worth it. Our generosity is having an important effect on the behavior and even evolution of these birds.
Take the goldfinch for example. In the 1960s, this was a rare bird. Today, goldfinches can be seen in many gardens. Other new visitors include the spotted woodpecker, which has left its usual woodland for food on bird tables. Evolution is meant to progress slowly: over thousands of years. Yet during the past few decades, the beaks of many kinds of birds have become longer because birds with longer beaks can get more food, and then are more likely to live on.
Actually, the British habit of feeding garden birds goes back much further. During the sixth century, St Serf of Fife fed a robin in his garden; during the winter of 1890, workers in London were seen giving their lunches to songbirds. The real change took place in the 1980s, when a few farsighted businessmen realized that encouraging the British to be more generous to garden birds can help them make money. Therefore, various kinds of bird food and modern bird feeders were produced. As a result, the number of species using garden feeding stations increased very quickly, from about 10 to over 100. Then, in 2005, Springwatch came, which turned our love of garden birds into an entertainment show.
Is bird feeding completely good for birds? Not everyone thinks so. Studies by the Zoological Society of London have shown that by bringing together many birds, bird feeders may help the spread of disease. In Australia, some bird experts believe—probably wrongly—that bird feeding creates a "dependence culture".
But we shouldn't forget one major benefit of feeding garden birds—it connects millions of people to the natural world. This is especially important for people who seldom reach the wider countryside. As I write this, there comes some noise outside my window: several birds were singing and flying around in my garden. It's a sight I could only imagine years ago, when feeding garden birds just meant throwing hard bread to them.
