Balancing Bird

Product Information

Here in the UK, we are putting vast amounts of supplementary food into the environment for birds every single day. In fact, work by Dr Melanie Orros and Professor Mark Fellowes at the University of Reading has estimated that the volume of supplementary food provided has the potential to support as many as 196 million garden birds. Astonishingly, that’s approaching half the total number of birds thought to be at large in the UK countryside*. Therefore, to balance the bird on the beak requires moving the COG forward and similar to a Seesaw with individuals of dissimilar weight we have to add, remove or reposition the weight. Do you feed the birds in your garden? We would love to hear from you why you do, or don’t. Add your views in the comments below.

Science - Any system of knowledge that is concerned with the physical world and its phenomena and that entails unbiased observations and systematic experimentation. Too little weight and the tail will point down, either increase the size of the balls or move them closer to the wing tip.You can also find the template and more details behind the physics in his book, Mr. Shaha’s Marvellous Machines: Adventures in Making Round the Kitchen Table. The project is just one of its featured STEM tutorials.

The balancing bird is a toy that has its center of gravity located at the tip of the beak. The center of gravity (also called the center of mass) is a special point on an object. It's the point at which the mass of the body is perfectly balanced. For example, the center of gravity of a pencil is in the middle. So you can hold a pencil up using just one finger if you place it underneath the middle of the pencil. Similarly, you can hold the bird up using one finger as well, if you place it underneath the beak.

Multiple independent studies indicate that the genuine pleasure we gain from feeding birds is what motivates us to keep doing it. Nowhere is this more evident than in Australia, where vast numbers of people put out food for wild birds despite widespread opposition from wildlife and conservation agencies. 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. This was used as a template by placing it over a piece of card, taping one edge to stop it moving and then using a modelling knife* to cut around the template and through to the card beneath.
