55 million birds killed by cats in the UK every year
BTO free guide to help cat owners to protect birds
Ground feeding birds like Dunnock are especially vulnerable to cats.
May 2010. Cats kill an estimated 55 million birds in Britain every year and such predation could be contributing to long-term declines of garden birds like House Sparrows. To help bird and cat lovers to reduce the impact of cats on garden birds, the British Trust for Ornithology (BTO) has produced a free guide.
Ground feeding birds predated by cats
No householder likes to see it; a pile of feathers on the lawn or a dead bird dropped neatly at the foot of the bed. Historically, predation of birds by cats was not considered a big issue - indeed, in the 19th Century it was thought that without cats some urban areas might be overrun by House Sparrows! However, the huge number of birds that are taken by cats annually could contribute to the long-term decline of species like House Sparrow. Because of their ground-feeding behaviour, other familiar garden birds, such as Robin and Dunnock, may also suffer from the activities of our cats.
How to protect birds in your garden
The BTO has produced a guide that outlines practical steps that householders can take to minimise the impact of cats on garden birds. For example, householders can spread out bird feeders so that feeding flocks might spot a cat more easily. Chicken wire of a suitable gauge can be placed around nest boxes and thorny vegetation (e.g. pyracanytha) can be planted to help protect nesting birds. In addition, sonic devices, which are triggered when a cat crosses in front of them, can help dissuade cats from using certain areas of a garden (e.g. around bird feeders). Bells fitted to cat collars might also give birds an early warning that a cat is present.
9 million cats in the UK
Dr Tim Harrison, BTO Garden BirdWatch, commented "Gardens contain important breeding populations of red-listed species such as Starling, Song Thrush and Spotted Flycatcher. With around nine million cats in the UK and only 59,000 pairs of Spotted Flycatchers, it is easy to see why some people are concerned about cat predation."
He added, "Public affection for both cats and garden birds is enormous, so the key is to minimise the impact of cats on birds while accommodating both. Nestling and fledgling birds are especially vulnerable to predation by cats, so now is a great time to be thinking about how we can help."
