A very easy method of recycled wire mesh makes an ideal bird nesting box for all types of garden birds, mainly the tits, wrens, flycatchers and robins, to name but a few. If you have or find a piece of old mesh large enough to go round a large coffee jar at least 3 times and about 1 foot in depth is ideal. Fold the wire in half then stuff with leaves and straw to make a sandwich, or use up last years moss from the hanging baskets, when filled with about an inch thickness of materials tie or secure the edges all round so the material does not escape. Roll into a tube shape and secure with either wire or plastic ties. Close off one end and secure with ties, you can now place this in a tree or bush, along the underside of a branch, in a hole in a wall or under the eaves of a shed or out building secured by plastic ties. With practice the open end can be twisted and shaped to suit several species, open ended for robins etc and closed to a small entrance hole for wrens and tits. As all the materials are recycled it costs nothing but your time and when in position is well camouflaged as the materials are all natural. I have had lots of success with this type of nest box, hope you do too.
