Never in the past has the public at large taken so great an interest in protecting and furthering the well-being of birds as at present. In addition to protective legislation, clubs everywhere are organizing to promote bird life and many citizens, old and young, are making bird houses and feeding tables.
One of the best forms of feeding tables which I have ever seen is shown in the sketch. It possesses a great advantage over the average table in being turned automatically, whirling about by the action of the winds and always keeping its open front on the lee or protected quarter. This is a good feature especially in the fall and winter, the very time when birds need and seek protection from storms and cold winds.
To make such a feed table almost any kind of boards can be utilized. The shelter may be of any shape or size to suit the tastes of the maker, but one constructed to the dimensions given will be found to work well in most localities. Along the center of the roof is attached a wing, A. which is an active aid in causing the wind to keep the open front turned away. The shelter turns upon a wood or iron rod which passes from the end of a post up through the central bottom and central roof of the structure. If wood is used for the rod, it should be about 1 in. in diameter and of hard stock. An iron rod may be somewhat smaller. Keep the holes well greased. The house should be given a couple of coats of white, red, or green paint, and the post painted to correspond. Feed and water are placed in shallow dishes on the floor and they should be blocked to keep them from sliding out. - Contributed by C. C. Fraser, Saginaw, Mich.
