CONVERTIBLE WINTER ROOST (12-1/2 h x 7 w x 9 d) Has the same dimensions as ’s Small Winter Roost but the front of this roost can be flipped to convert it to a birdhouse after the winter season. Position the front with ventilation slot at the top and remove the three interior perches and the roost becomes a nest box. Sustainably grown 1 thick Eastern White Pine provides superior insullation. Hand crafted with pride in Maine.
