(After Ladd.) trivance, a moving food shelf may be hung from a wire reach- ing to some near-by tree where the birds may be fed at first, and when they have become accustomed to this, the 'trolley' shelf may be moved nearer and nearer the window shelf day by day, until they have learned to feed there, when the use of the trolley may be discontinued. If the ground birds do not come to the shelf at first, they may be fed on the ground near by, and then tolled nearer and nearer the shelf until they follow the tree birds to it. A little bush or tree set upon the shelf and supplied with food attached to the branches will give the arboreal species a chance to display their natural feeding habits, while the ground birds will feed mainly on the shelf. A food hopper may be provided, as shown in Fig. 17. Such a hopper filled with seed will feed it down as the birds want it, so long as it is kept clear of snow and ice. The Windoiv Box. In some respects the covered shelf or window box is an im- provement on the outdoor shelf. In it the food and the birds are protected from storm and wind, and it brings the birds practically into the room. Birds soon become accustomed to it and frequent it in con- siderable numbers. The Weathervane Food House. The weathervane food house is the most perfect device yet invented for outdoor feeding, but it should have a hopper built into the top that can be filled with seed. This hopper should be large enough to hold a month's supply of seed, and should be made to 'feed down' as fast as the birds eat the food at the bottom. The weather- vane food house swings with the wind and always keeps the opening away from wind and storm. The food house shown in
