All over the country, particularly in the West Coast, interest in bird houses has been steadily increasing. People are putting up bird houses in their own backyards. In stores, a myriad of new kinds of bird houses have emerged. You now have an endless array of bird houses to choose from, depending on your preference of design, size, or color. One of the most popular specialized bird houses right now are the martin bird houses.
Just as there are several different types of human homes, there are also several kinds of homes for birds. There are bird houses designed for single occupancy, called cottages or shanties, and there are also larger bird houses called churches, cathedrals, or condominiums, which are built to provide shelter for as many as a hundred birds.
Martin bird houses are of the condominium type. The most common martin bird house can accommodate about 15 birds. Each bird in the avian condominium has its own room. There are usually several levels of this bird condominium. Some of the larger martin bird houses have as much as 12 levels, with at least 10 compartments in each level.
