There is nothing more beautiful if we have a garden or a terrace, than to see how birds visit us, so to achieve this. An effective “trick” will be to make birds find a house in one of our trees or in a corner of exterior of wooden bird houses in garden not only give joy with their songs. And their presence as we just mentioned. But in a way it is important to visit us if we consider how birds can eliminate 7,000 mosquitoes every day. And not only that, are capable of killing up to 800 grams of insects. During winter, birds that remain in our country, so-called avifauna, have security and nutrition problems. Especially in cities, so we can help them with certainty that, by staying in our territory, during spring and summer will be of great help against our enemies in garden.
Therefore, a good idea is to build an aviary, which could even become a nest for them to have offspring. And we can also leave them food so that they are always fed. It is important before making our bird house that we make sure it is made of wood. This is best material for aviaries. And also, best thing is that wood has a thickness of 2 cm to guarantee protection against low temperatures. Trailing edge must be rough, something we can achieve if we pass a rasp. Birds can more easily take flight from rough surfaces. When designing wooden bird houses you have two possibilities. Design a small, front and round opening, and arrange an opening on other side. Or behind to allow inspection and occasional cleaning (remove old nests, hunt any rodent intruder …). Or you can design a wider rectangular front opening that also represents access for cleaning.
In first case, wooden bird houses will be “close” and entrance hole for birds should have a standard diameter of 2.8 cm. Avoid making bigger holes because birds most in need are passerines. And other small birds (which are in fact birds that most visit garden). Now, if you see larger birds you can make a hole with a diameter of 4 cm. In second case we hypothesized an open birdhouse. Here, front part is formed by a parapet of variable height depending on birds you wish to lodge. Parapet should have a height of 8 cm if you want to lodge passerines or for example, robins … a lower parapet of 2.5 cm is useful if you want to attract birds like cardinal flycatcher, also called fly swatter or flycatcher.
