But, inevitably, feeding does affect the birds we see around us. We recently showed that our changing bird feeding habits can be linked to the large-scale restructuring of garden bird communities and the growth in urban bird populations across Britain. Feeders have become better at attracting a broader range of species over time, with many species using feeders much more frequently now compared to 40 years ago. As a consequence the populations of feeder-using species have increased significantly in urban areas of Britain, while those of other urban birds (which do not use feeders) have remained stable on average.

Can you stand on one leg or spin around without falling down? Staying upright is all about balance. Make a balance bird to see some surprising feats of balance. Materials

If you’d like, you can color your bird.

Tape one penny near the tips of the wings on the underside of the bird. Try to put them the same distances from the edges on both sides.
