How to Build a Sparrow Bird Box
Sparrows are in trouble - their population has halved for reasons we don't understand. A sparrow bird box offers them a safe, easy to find home and can help boost their numbers.

Sparrow nest boxes can be placed under the eaves of houses or high on walls. They should be away from any wires or other structures that could cause a problem. Getting the homeowner's permission is a good idea before placing a nest box in their property. Alternatively, a sparrow box can be mounted on a pole or post in the garden. The box should face north or east to avoid direct sun and heat, and ideally be located away from buildings and human activity.

The best sparrow bird box is made from wood approved by the Forest Stewardship Council (FSC). A hardwood like oak or beech is recommended as it will last longer than softer woods, such as pine, which can warp. yến vụn giá rẻ should be at least a inch thick to provide insulation and protect the birds from cold and damp.

A basic birdhouse can be constructed using a plank of wood about one inch thick and four feet long. A hole about one inch in diameter should be drilled through the middle of the plank at four inches from each end. The holes should be located at a height that will be comfortable for the birds, but will keep predators out. The roof should be hinged for easier access for cleaning and maintenance.

It is important to use a preservative on a sparrow bird box that is non-toxic and will not damage the birds if they come in contact with it. A water-based preservative is usually the best option, and is readily available from DIY stores or hardware shops. When applying the preservative, follow the manufacturer's instructions for maximum protection and safety.

Depending on the site, it is possible to lure the birds into the box by offering a mix of native wild seeds such as millet, wheat and cracked corn. Some people also use black oil sunflower seeds to attract the birds. Alternatively, some bird-lovers choose to wait until the house sparrows move on from their territories before installing a nest box.

It may be possible to encourage other species of native songbirds to use a sparrow bird box by removing any existing nests with sparrow eggs or hatchlings from the box, and promptly replacing them. This can be time consuming, and may not work as well in areas heavily infested by house sparrows, but it has been successful for some people.

Another option is to install a box designed specifically for the native birds you want to attract, such as a bluebird or tree swallow house. These houses can be purchased or made from plans. The nest boxes should be sited where these species like to nest, and with plenty of food nearby. It is also important to make sure that the box has an entrance hole that will be suitable for the preferred bird.
