Birdhouse

Spring arrived hotter than ever. Suddenly all went out for a walk. Urban trees and urban birds are playful. In one of my walk I noticed that good people have already placed birdhouses. So I came up with the idea to design a birdhouse. 

The idea for the design response contains several problems. Hooks that mount easily, which can be modified and multiplied without much problem. 

I did research and found out some facts about the design of little houses for birds:

Hole Diameter Matters - To make birds feel welcome at your birdhouse, the entrance size is critical. A fraction of an inch too small and your desired birdhouse residents will not fit into the house, and a fraction of an inch too large and you may find less desirable birds such as house sparrows and European starlings usurping the birdhouse. While different individuals of the same species may vary slightly in size, these basic birdhouse entrance hole dimensions can help ensure that your birdhouse attracts the types of birds you want to invite to become backyard residents.

Predator Protection - Backyard predators can include pets, stray cats, raccoons, squirrels and even other bird species that may kill or injure baby birds either as food or to take over the birdhouse for their own nesting site. To make a birdhouse safe from predators:

• Remove any perches from the house. Birds do not need them to access the house, and they only provide convenient handholds for predators.
• Be sure the birdhouse opening is the right size for the species you wish to attract. If the opening is too large, predators will have easy access to the nest and other bird species may take over.
• Position the birdhouse far enough away from brush so predators cannot stage an ambush, but close enough to plants so parent birds can easily scout the area. Five to eight feet of distance is sufficient for most birdhouses. Similarly, keep birdhouses away from popular feeding areas to prevent territorial conflicts between feeding birds and nesting parents.
• Choose natural colors so the birdhouse will blend into the surroundings. Browns and dark shades of green are the most suitable choices and will be the most attractive to birds. If possible, use only natural materials that lack ornamentation to keep birdhouses concealed.

Climate Safety - A safe birdhouse is snug and comfortable for nesting birds. To keep a house safe from the weather, follow these tips.

• Choose a birdhouse design with ventilation holes in the upper part of the walls to circulate fresh air and prevent the house from getting too hot or suffocating. If the design does not include ventilation holes, drill unobtrusive holes in the corners or sides of the house.
• Position the birdhouse so its opening does not face into direct sunlight or prevailing winds. Full or partial shade will help keep the house cooler, and a more protected location will be safer.
• Angle the birdhouse so rain cannot easily run into the opening or through ventilation holes. Some birdhouse models include an angled face to ease water runoff, and a larger roof overhang can also help keep the interior of the birdhouse dry.
• Avoid birdhouses that are constructed of metal. Metal houses will become miniature ovens in summer heat, and reflective metals are highly visible to predators.
