By actively placing, specially designed artificial hollows or nest boxes high in young windbreak trees then these birds can be attracted to the property. The availability of habitat for wrens and magpies, the problem of caterpillars and crickets will become a lot less. Tall trees will help the magpies and shrubs with closed canopies will help the wrens. In twiggy orchard trees, such as macadamia wrens will nest, but orchard routine will disturb them. Small blocks of shrubbery within a windbreak can assist these delightful little birds.
Magpies seem to survive in most places.
Tall trees within a windbreak will help them feel at home in an orchard. Flowering trees Probably the greatest benefit for biological control of pests and the assistance to crop pollination is to have a number of flowering tree species make up an orchard windbreak. By planting a range of trees that flower throughout the year, but not at the same time the orchard crop, a food source and habitat will be produced for beneficial birds and insects. Many nectarivorous birds are also active insect eaters. Honey eaters are known to hawk moths such as Heliothis and the moth of the flower eating caterpillar.
