After you have birds come into your backyard and they are enjoying the experience, a few tips in order to really enhance that experience and to make it grow. A lot of people cite the fact that they like to get a larger variety of birds in their backyard.
So in order to do that, you have to put out different types of food. So you started with a basic feeder and feeder mix, and now it's time to add a tube feeder with some Nitroseed in it, and that will begin to draw in very colorful finches, or a platform feeder with some safflower in it, and that will draw in cardinals. So try adding different varieties of food and feeders to your backyard experience, and you will be getting more birds and a larger variety.
Another very important tip is that you keep the feeders full at all times. If the feeders are left to become empty, what will happen is the birds will actually disappear and move onto a different habitat.
