When creating a bird sanctuary with your class, it is crucial that you keep appropriate trees and shrubs in mind. While this can determine the availability of a bird's food, it can also provide the bird with adequate shelter and nesting sites. You should plant native species according to the type of bird you wish to accommodate. Tanagers, for example, are one of the many different species that rely on dogwood trees for both shelter and food. Determine the species of birds that you wish to attract and — with your pupils — select and plant supporting shrubs and trees.
Ask students to build bird houses to be placed within the bird sanctuary. Many if not most commercially produced bird houses are made of cedar, but they may also be constructed using reclaimed wood or any other sturdy wood or material. Bring various materials into the classroom, including pre-cut wood, wood glue and clamps. Encourage students to bring similar materials.
Birds require a clean and steady supply of water. With the class, install a bird bath or an alternative water source. The bath can be made using a wide range of inexpensive but effective materials — including garbage can lids. With the students, make sure the water supply stays clean. If the water becomes dirty or stagnant, it might attract insects and promote mold.
Provide the sanctuary with an alternative feeding option. Seed feeders are helpful, but you may also provide suet feeders. This is done by mixing fat trimmings from meat — usually available at a grocery store — with seeds or fruit. The fat should be melted — or liquified — before the seeds and fruit are added and the mixture formed into cakes. When cakes are finished and have cooled, they may be placed in a mesh bag and hung on low branches of trees.
