1291 A. Experimental Shelter for Rhody. (See notes, p.1291) These pictures were taken while the shelter was resting on a box, which formed no part of the structure, before being placed in the roost tree. Fig.1. Fig.2. As will be seen, the house is very open, the idea being to give the maximum of protection (from the rain principally) and yet create in him a no sense of confinement. At the same time it was intended to protect him from the rear (from wind and enemies) but give him an almost unobstructed view in all directions. Tail sup- port was also an essential feature, as was also shelter from up- wardly trending winds, a certain amount of shelter from side winds also prevention of wind working underneath his feathers as he lay on the platform. There were further considerations affecting the design, as will appear later. Fig. 1. shows the house to consist of a small platform for him to lie upon, with a rear wall and two narrow side walls The platform has a low parapet surrounding it--low so that he can spread his body feathers out over it and keep wind and rain from the floor and from getting under him. The whole is surmounted by a roof of wire netting impregnated with cellulose acetate: "Flexo- glas". It is, therefore translucent. Its upper surface is dotted with splatches of green and brown paint--also white--to make it inconspicuous from above (hawks) and, from below: both on R's ac- count as well as that of casual passers by, more or less resemble the canopy of the tree within which it was to be placed and not cast heavy shadows. It is braced by two diagonal struts for stiff- ness. (The roof would be flexible and crackle in a wind otherwise) The narrow side walls make it possible for him to thrust his head out and look to the rear. There is a window in the rear wall, also splotted sparingly with paint, so that he can look through that to the rear without showing his head. (See Fig.2.) The wind- ow has a bar across it inside to keep his stern and tail off of the cold glass and avoid their getting wet in the event of leaks.
