A birdfeeder and a birdfeeder kit that includes a frame dimensioned for mounting within a window, a first edge, a second edge, and a floor fixedly attached between the right portion and the left portion of the frame. A viewing enclosure, having a transparent window portion, is rotatably attached to the floor such that the viewing enclosure abuts a second edge of the floor and the frame when in a viewing position, and exposes the floor when rotated to a filling position. In operation, the frame of the birdfeeder may be mounted within a window, the viewing enclosure may be rotated to said filling position to allow a quantity of bird food to be disposed upon the feeding surface of said floor, and the viewing enclosure may be rotated to a viewing position to allow a bird to be observed through the window portion of the viewing enclosure. The preferred birdfeeder includes a photosensitive window portion having a substantially arcuate surface that is held within a channel in the top, bottom, right side and left side of the viewing enclosure, a feeding surface having a tapered rain groove for draining water from the floor and a seed tray removably disposed upon the feeding surface for receiving seeds. It is also preferred that a right side panel and left side panel be attached to the right and left sides of the frame respectively such that the birdfeeder completely occupies a window opening.
