Choose a simple design like a pinecone coated in peanut butter and birdseed, a plastic bottle with holes cut for perches, or a wooden platform feeder, since a design matched to your tools and skill level is far more likely to actually get finished and used. Use plain birdseed or suet rather than bread, since bread offers birds almost no nutritional value and can cause health problems if it becomes a regular part of their diet. Hang the feeder at least a couple of meters from windows or place it directly on the glass with a suction mount, since a feeder positioned in the awkward middle distance is the most common setup that causes birds to fly into windows. Make sure any holes or openings drain water rather than collect it, since birdseed left sitting in water quickly grows mold that can make visiting birds sick. Hang the feeder high enough and far enough from fences or low branches that cats and squirrels cannot easily jump to it, since an easily reached feeder gets raided constantly and rarely attracts the variety of birds you are hoping to see. Clean the feeder every couple of weeks with hot water, since built-up droppings and old, damp seed are a common source of disease that spreads between the birds visiting it.
