Abstract
A bird feeder which is removably mounted on a window pane, having a bracket member with a shelf on which a removable feed tray nests. The feed tray for solid bird feed is an open-topped pan with a lip on which birds may perch and has a well section extending downward from the main bottom of the tray which fits into a hole on the shelf. The feed tray for liquid bird food is provided with a vividly colored cover which fits snugly into a lip. The cover provides several conical shaped feeding ports for access to the liquid bird food. Models of the bird feeder may be made with different length shelves to accommodate the number of feed trays desired.
